Angular Unconformities

Here is a 200 year old illustration of the Hutton Unconformity:



The Grand Canyon threads note such an angular unformity in the Grand Canyon. 

Such structures immediately falsify any Flood Geology that requires the Earth (or the fossil bearing formations) be under 10 thousand years old.   

It is thus not surprising how dead quite the YECs are on the subject. 

The question becomes to any YEC: how can an angular unconformity form?

 

 

Nice. I'll have to remember this one. What's the original source of the picture, Ardipithecus?  Did you get it off the web or scan it?

I scanned it.  Though it is very easy to find.  You can find it in Time's Arrow, Time's Cycle by Gould.  It is also in Basin and Range by John McPhee.  That book can found as a book or in the five-book omnibus Annals of the Former World which won the Pulitzer.   It was originally in John Playfair's Illustrations of the Huttonian Theory of the Earth published in 1802.

 

Here is a generalized diagram of an angular unconformity:



As mentioned before there is a rather famous angular unconformity at the Grand Canyon.  The GC has other types of unconformities as well:



AU = Angular Unconformity

NC = Nonconformity

LU = Local Unconformity

D = Disconformity

And just as I ask how an angular unconformity could work in Flood Geology, I could ask the same for the local unconformity (indeed the problem is even bit worse for the YECs for that type).  Or for that matter the local unconformity plus the angular unconformity.  And then there is the nonconformity and several disconformities.

Just on the basis of these features one must have many cycles of sediment being laid down followed by erosion followed by sediment being laid down.

The creationists seem to be staying away in droves!  Why am I not surprised?

It seems simple enough to me.

How does something like this form?

And apply the lesson to the Grand Canyon.

 

 

 

And that is sad since angular uncomformities are geology 101 and high school level stuff...

.....and what about it?

Angular unconformities like those pictured above illustrate how older rocks are tilted or folded by tectonic processes, are eroded, and younger sediments are deposited on that erosional surface and are lithified. An example of this is near the bottom of the Grand Canyon.

The "what about it" part was already mentioned by ardipithecus (as it is in the other Grand Canyon threads): these features falsify the notion that the Earth's geology can be explained by a global flooding event (particularly one that lasted a year or less, according to Young Earth Creationists) on an Earth less than 6-12 thousand years old.

The point is that YECs have yet to address how a geologic feature like this could form under the assumption of their Earth model (as well as other features listed in other recent geology threads).
