In building the garden beds, I came across a lot of rocks. I filled up the voids in the cement blocks with the rocks. Some of the bigger rocks I whacked with a hammer to break them up so that they would fit the voids better. This was the most interesting rock to break open:
I thought this was so interesting looking I did some googling and came up with this: http://en.wikipedia.org/wiki/Liesegang_rings_(geology)
I never managed to take a geology class- or I manged to never take a geology class, whichever one implies an active avoidance. The wikipedia article is pretty dense with terms I don’t pretend to understand. One interesting tidbit is this detail: “Chemical weathering of rocks that leads to the formation of Liesegang rings typically involves the diffusion of oxygen in subterranean water into pore space containing soluble ferrous iron.”
That could certainly apply in this case, as the Arkansas River currently flows roughly one mile from where I dug the rock from the ground.
Hey,
what a beautiful rock!
Actually I’m trying to find out what kind of rock it is, so I were curious if someone here could help me find out. I’m doing this project on Liesegang rings, and this is a really good example. Just need to know what kind of rock it is!
Really nice picture 😉
Sorry, I’m not much help on the rocks. I’ve got a ton (close to literally, I’m guessing) in the yard, but i don’t know what they are exactly. If I find out, I’ll post here.
Okay,
thanks for your quick answer! I’ll keep an eye on this topic 😉
