What does orogenic mean?Yes, but they are not due to recent blasting. In fact they are usually associated with an orogenic event. Or in other words, when the mountains were made water underneath heat and pressure dissolved gold out of some areas and redeposited it in quartz veins. The orogenic event was millions of years ago.
You're my rock guy SZ. What do you mean on a fresh surface? There are no clear glassy pieces on this rock. I can post some more pics of the rock. Finding where the rock came from will take leg work.

Is there any chance of finding the bigger piece of rock that this came off of?To get a fresh surface you may have to break the rock. It is much easier to identify individual minerals if they have not been exposed to weathering. And the clear glassy pieces that you would be looking for are the size of one crystal of the rock, so you might miss them if you don't have a fresh surface.
I have no idea. Can you tell me where you found that rock?Is there any chance of finding the bigger piece of rock that this came off of?
I don't believe it is it looks organic to me and natural not done by man.You sound like you know a lot more than I do about this stuff.. But I don't understand your point as it pertains to my guess that the rock came from some kind of mining operation or construction job. Those grid lines on the face of the rock look like stuff they lay out when using explosives.

Okay, did some research on your latest info. It is probably a nepheline syenite. That is a granitic rock, meaning it is made mostly of lighter density minerals but it is not a granite since it has little to no quartz. So you not seeing quartz sounds more than reasonable.Southern Arkansas. On a mountain. No water or river flows nearby.
How do you explain the grid pattern? Those lines are too perfect to be natural..
It is natural, those look like mineral veins (probably some sort of quartz), which would be very difficult to produce artificially; the pressure, temperature and time required for them to form is very hard to substitute. It is unusual that these are so close to perpendicular, but not impossible as SZ has explained.How do you explain the grid pattern? Those lines are too perfect to be natural..
So do I.Frankly, I find it suspicious.
Aw man...It is natural, those look like mineral veins (probably some sort of quartz), which would be very difficult to produce artificially; the pressure, temperature and time required for them to form is very hard to substitute. It is unusual that these are so close to perpendicular, but not impossible as SZ has explained.
I guess they could be painted on to look like mineral veins. To show they're not, we need @crjmurray to go back up the mountain, this time with a geology hammer, find the rock again, and smash it in half. A pair of safety goggles are recommended, and protect me from any liability for the cost of subsequent eye surgery.
Clearly it's the tile flooring from Noah's dinosaur farm. Proof of the Flood!I found a rock...

RockCan somebody explain why this rock looks this way? Frankly, I find it suspicious. And to keep this relevant to the C&E section, I'd like the young earthers to take a go at this as well.
Our first young earth explanation!Clearly it's the tile flooring from Noah's dinosaur farm. Proof of the Flood!
I have no geology qualification at all, so I'm at least as expert in the field as any YECer.Our first young earth explanation!
I'm really more sad about the prospect of breaking my rock....It's good for you. All that fresh air and exercise....
