April 17, 2016 Weekly Geology Guess

April 16, 2016
Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:
With my discussion on Alabama Geology, I have gotten the geologic cart before the horse.  I have not included a basic discussion regarding rocks and all the various kinds of sedimentary, metamorphic, and igneous rocks.
We will start with Sedimentary Rocks.

“If it ain’t grown, it has to be mined”
Sedimentary Rocks

>    This is one of the best and simple explanations of Sedimentary Rocks.
“Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris.”
>    Me thought I could just sneak through the rocks, but NO.  The Devil is in the Details.  All of these rocks are found in Alabama, especially the Highland Rim, Cumberland Plateau, and the Valley and Ridge  Physiographic Provinces.
“Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution.”
“Organic sedimentary rocks such as coal, some dolomites, and some limestones, form from the accumulation of plant or animal debris.”
Note:  Had out of town company last weekend, so no post.  Thanks, R
Thanks,

Another Editors Note:  It is the intent of this site to keep this discussion as simple as possible, so as to educate the interested general public and not to discuss with the geology crowd the latest geologic theories and nuances.  Thanks, R
