We bandpass filter our data 3-6-60-90Hz.

So the chances are we lose this noise.

I can't access the paper to find out what frequencies we are talking about here but the abstract says low frequency.
Am I reading that correctly? You bandpass at 3 and 6 Hz?

Wow...I can't even reproduce frequencies below 40 Hz!

How to move a continent well just speed up and hit the brakes.
Modern scenery explained.
You don't just "speed up" the moving of continents. Sorry.

The deepened seas is a good idea for where the water went to. The seas before the flood were shallow relatively.
Its reasonable from biblical foundation and evidence in the field.
It's completely unsupported by anything. There is no evidence for your claim.

This thread was about where did all the water go after the flood.

Actually it is about where the water needed to flood the earth came from, where it went afterwards is an ancilliary question.

Ew creationists gave good answers of where it went.

Really? I didn't see any, perhaps you could summarise what you thought were the best answers as to where the water went.

Then you guys change the subject.

You appear not to have even cottoned on to what the subject is. Hint: look at the thread title.

"Source of water for the flood"

Now look up source in a dictionary.

For me you talked about continents moving being impossible.

In that case you comprehension skills aren't that great. All geologists are fully aware that the continents and plates are in constant motion in rates of cm per year. That is measurable via GPS.

Then you say the bible is not a legitamate witness

It isn't a geological text book that is for certain. IT may have its uses but illuminating science is not one of them.

and then you say geologists know the truth.

Sure do, not the whole truth, but substantial portions of the truth as to how the earth was created and evolved.

I know the bible is a witness but I don't rely on it to make the creationist case.

Good for you, you don't want to make things too easy for us.

We use the data.

Really? Just quoting other people data that you don't understand doesn't really constitute using data you know.

Saying you are the experts is just a way to avoid criticism of your ideas.

Nothing wrong with valid criticism, it is how science progresses, haven't seen any from you though.

From my readings in geology every geology graduation class overthrows the previous ideas in geology.

In that case your readings in geology have either not been extensive or they haven't included comprehension of what you were reading. Ideas have changed in geology, but they don't have major overhauls on a yearly basis.

We haven't had a major paradigm change since plate tectonics was explained 40 years ago.

It is not scientific but speculative.

That is a good summary of your posts, but not of geology.


The separation of the continents is one of the best things to come along in geology for the gain of creationism.

Really. I would have thoughtthatthe fact we can measure the continents moving and we can extrapolate those movements back over millions of years would seem to be to be a complete destruction of the YEC position.


It is the source for the great movement of sediment and volcanic chaos that is found in the data of rocks in the field.

Plate tectonics is indeed the driving force behind global geology, it is a measurable force and we can see by simple uniformitarian extrapolation that it has been in operation for millions of years.

The continents did move and this fits fine and is welcomed by creationism.

Well it is hard to deny reality all the time, they just mess with reality by saying that plates moved a lot faster in teh past, an idea that has no supporting evidence and which energy physics suggests would lead to a molten ball instead of a planet.


How to move a continent well just speed up and hit the brakes.

And destroy the planet.

Modern scenery explained.

If you live on a molten ball, I don't.

The deepened seas is a good idea for where the water went to.

The seas haven't deepened.

The seas before the flood were shallow relatively.

You have no evidence to support that.

Its reasonable from biblical foundation and evidence in the field.

What field evidence have you collected :D

You are not showing their was too much water.

No we have comprehensively shown that there is not enough water on earth to inundate the earth.

We record all frequencies but we have an analogue filter built into our recording apparatus that is full off at 3Hz and fully open at 6Hz, we also have a digital filter in teh recording computer software set to the same levels. We record to a Nyquist frequency of 125 Hz, but in processing our upper filter is fully open at 60Hz and fully off at 90Hz. So we are generally working of frequencies between 6-60Hz.

Yeah, you'd have to be at around 120 to sample up to 60...

That's crazy....what kind of element are you using? Would I be correct in speculating that it's enormous (as far as elements go, anyway)?

Our source is a tuned array of 28 airguns from 20-250 cuin totalling 3090 cu inchs. It is tuned so thatthe bubble collapse is minimised so we only get one strong peak input into the earth.

So that is a pretty powerful bang. It isn't as spiky/white as an explosive source like dynamite would be, but it is far less dangerous and more environmentally friendly

Most hydrocarbon source rocks would have very low permiability as they are organic shales.

In that case it is quite possible that a reservoir cap rock has a higher permiability than the source rock as they would both be fairly impermiable.

So, you may tell me that how could the trap accumulate anything if it leaks faster than it gets?

Do you want to talk specifics because you question really makes no sense in the general form above.

Once again it looks as if you have trawled through a basic geological text without really understanding it.

Try again.

You can save this crap from now on as no one would pay attention to it.

My reply is directly below the post.

You and TexasSky appear to view this mantle water as a great big body of H2O like an underground lake.

That isn't what it is like, read the article TexasSky linked to, but apparantly didn't read.
Can you read the small print on the scale of the attenuation profile? Could you explain the unit for me? It read something like "din(I/Q)%". What is that?

Thanks, brother. God gives me a strong sense of logic. And like my son usually tells me, my problem is the lack of love (he likes to say that I "kill to dissect"). I loose my control easily when I see repetitive stupidity. Thanks for the reminder.

If we could squeak a little geology in here, could you explain how this works? Is it that the hydrocarbons are trapped in the source rock by dint of its impermeability, with the "cap" rock really serving to contain them at all?

I mis-spoke a bit when I said that most hydrocarbons are generated from organic shales, this is true of oil, but a lot of gas is generated from coal measures.

The basics are ( for oil in this case ):

Source rock - shale - in oil window ( temp correct to generate oil).

Reservoir rock - permiable rock with good porosity for oil to reside in.

migration path from source to reservoir

trap to collect oil - a simple trap would be an anticline

Cap rock - impermeable rock lying over trap to stop further migration of oil.

wikipedia probably puts it better:

A prospect is a potential trap which geologists believe may contain hydrocarbons. A significant amount of geological, structural and seismic investigation must first be completed to redefine the potential hydrocarbon drill location from a lead to a prospect. Five elements have to be present for a prospect to work and if any of them fail neither oil nor gas will be present.
  • A source rock - When organic-rich rock such as oil shale or coal is subjected to high pressure and temperature over an extended period of time, hydrocarbons form.
  • Migration - The Hydrocarbons are expelled from source rock by three density-related mechanisms: the newly-matured hydrocarbons are less dense than their precursors, which causes overpressure; the hydrocarbons are lighter medium, and so migrate upwards due to buoyancy, and the fluids expand as further burial causes increased heating. Most hydrocarbons migrate to the surface as oil seeps, but some will get trapped.
  • Trap - The hydrocarbons are buoyant and have to be trapped within a structural (e.g. Anticline, fault block) or stratigraphic trap
  • Seal or cap Rock - The hydrocarbon trap has to be covered by an impermeable rock known as a seal or cap-rock in order to prevent hydrocarbons escaping to the surface
  • Reservoir - The hydrocarbons are contained in a reservoir rock. This is a porous sandstone or limestone. The oil collects in the pores within the rock. The reservoir must also be permeable so that the hydrocarbons will flow to surface during production.

it couldn't accumulate in those circumstances

Just calling it like I see it.

You post like someone pretending to know something about geology rather than someone with any real experience. It looks like you have spent 5 mins scanning the internet and posted what you read.

If you are actually a geologist I apologise, but sooshould the seat of learning that claimed to have educated you in geology.

It is unknown and is a variable. You do not correct anything until you know what to correct.

If you do not use your brain in this forum, you are not using it anywhere.
And still you provide no evidence for your assertions.

But I think I know why.

You are incapable. You hand waive and dance around subjects spitting forth assertions and denigrating your debating opponents and when it comes down to it, you can't provide any evidence for anything you say. At this point you degrade into insults, flaming and baiting.

I used my geology knowledge to propose a possible cause of global flood. You do not take it. That is fine. But why are you here? Is "I don't believe you" or "the model is ridiculous" the best thing you can say to a Creation hypothesis? Are you here to give challenge to Creationist with your best knowledge? If so, where is your challenge?

Actually I started off simply asking you a couple of mechanistic questions around your hypothesis:

What is your water budget from the mantle?

How do you get it quickly from the mantle without destroying the planet or parboiling the surface?

Where did it all go after The Flood?

Why is our planet's tectonics the same now as it appears to have been way back in the geologic record, something that would likely not happen if you suddenly outgassed the mantle.

(Note the water serves important puproses in the mantle phases, including but not limited to melt temp and rheology of the mantle.)

Since you are not good in petrology, sedimentology. It is pretty flavorless by seeing you challenge me with naive questions.

You are getting quite insulting here. I don't know where you got the idea that I'm not good in sedimentology. Igneous and metamorphic petrology may not be my area (and note I am being honest here on my skill set), but sedimentology is much closer to my field (coal and organic geochemistry, my thesis was related to hot basinal brine migration into reef-deposit-hosted sulfides in the mid continent U.S., and I spent a year working for Peabody Coal correlating and mapping coal reserves, so sedimentology is not outside of my bailiwick).

I like to see that you are able to give a blow based on your best knowledge. So, throw to me your low T organic geochemistry argument as a challenge against Creationism. I am going to your field to see what is your qualification to challenge the science in the Bible.

If we are talking Literal Genesis then we have an extremely short time frame for the earth's history, yet the rock record doesn't show anything of that nature.

In point of fact I don't feel the need to support the bible with organic geochemistry issues. If, however, a YEC were to come on here (as they often do) and claim things about the origin of coal or petroleum, then I'm glad to address those issues.

To my knowledge the Bible is pretty silent on organic geochemical topics.

If you do not have any challenge to give, then wait for a while, I will throw one low T geochemistry stone to you.

I look forward to that like there's no tomorrow.

Believe me, I would dearly love to see a "stone" thrown to me.

It is not my field. But at least I think I might be able to give you some hard time in your field of knowledge.

That is amazing hubris. I am always amazed at Creationists who seem to know no humility. Which I find doubly ironic from Christians.

I have the humility to know that I might be mistaken on a topic. So when you started throwing out LREE's and alkali metals as volatiles, I was honestly confused if perhaps I was simply misremembering something. Thankfully Molal and Baggins have reinforced my initial feeling that you were just...off there.

Do keep in mind that while I am trained in geochemistry, I work as a regular R&D chemist. Commodity minerals are my current area of expertise, so while I am not an igneous petrologist per se, I am not a complete idiot in these fields.

Your tone has turned quite negative and dare I say sort of vicious of late.

So, if you can make a good shot, I am ready. Otherwise, you just wait. But, it would also mean that you already lose the first round.

Oh sheesh, some sort of p****ing match?

Please don't bring up the old cannard of [sup]14[/sup]C in coal, it is likely de novo generation

Apparently [[sup]14[/sup]C in coal] correlates best with the content of the natural radioactivity of the rocks surrounding the fossil fuels, particularly the neutron- and alpha-particle-emitting isotopes of the uranium-thorium series.(SOURCE)

Please also don't go off into the weeds on abiogenic sources of the worlds petroleum deposits. While there may certainly be abiogenic organic compounds in the rocks somewhere, the vast majority of petroleum we utilize carries within it the detailed history of its origins in the form of porphyrin rings and pristane/phytane derivatives from chlorophyll as well as numerous other biomarkers.

It takes extremely deep time to accumulate sufficient organic material in the black shale source rocks that ultimately generate petroleum.

So, please, "throw me a stone" on this one. Show me how badly I do in this field. Impress me with your knowledge.

But do try to keep the ad hominem commentary to a minimum, unless you would like it returned in kind.

Am I reading that correctly? You bandpass at 3 and 6 Hz?

Wow...I can't even reproduce frequencies below 40 Hz!

Totally off-topic, but back in unnergrad my roommate and I took a "synthesizer" class in the music department (using an old Arp 2600 analogue synthesizer) and we had an oscilloscope. We hooked it up to a microphone and I sang a perfect square wave for about 30 seconds.

So, if people tell me I don't have any skills I can always fall back on that. Do you realize the incredible control over harmonics that requires? Square wave only contain odd-integer harmonics.

So, yeah, I may not be an igneous petrologist buy I can selectively eliminate odd-integer harmonics when I sing.

(actually I can't sing, I have a very annoying voice...probably because I don't have those even-integer harmonics).

Now, back to the discussion...

Back in a former job we had a piece of equipment for measuring carbonate scale build-up that had an annoying noise signal in the temperature output. I used Excel to run a fourier-transform on the time-domain output of the signal and found a dominant frequency for this "electrical noise" of 0.3Hz. I was rather hoping it was going to be obvious what was going on with the instrument. It wasn't like I was going to be able to filter out the signal, but when I saw it had a period of 3 seconds per cycle I realized I was way out of reasonable space.

I think it turned out to be some weird "sampling" setting the software had. After all that work I figured out that there was a simple software setting to eliminate it.

Still it was fun to play with the signal and the noise.

(When I was in my only geophysics class back in the late Paleocene I remember thinking how dreadfully boring signal processing was...turns out I was incredibly wrong! But it took about 20 years to figure that out.)

Empirically we see oil accumulating in reservoirs precisely because they have an impermeable cap or boundary. There's no theory here, no mystical "guesses", just the way it is.

So, Juvenissun, perhaps this is the opportunity for you to throw us a Low T organic geochem question of some specificity:

Where do you think most oil comes from?

I'm obviously more than happy to meander away from the mantle topic (the details of which you still haven't really fleshed out).
