May 1, 2016 Weekly Geology Guess

May 1, 2016
Greetings from the Bluff Park   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 continue with Sedimentary Rocks.
“If it is black it is beautiful”!

“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.”
“Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution.”
>    for this week.
“Organic sedimentary rocks such as coal, some dolomites, and some limestones, form from the accumulation of plant or animal debris.”
We will combine both types of limestone and dolomites, both chemical and organic.
Dolomite:     (calcium magnesium carbonate, ideally CaMg(CO3)2 )

Attached is a handy guide to rocks by the USGS (US Geological Survey).  Simple in terms of Petrology, but still detailed.  R

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

Next week we will we will crush up the sedimentary and igneous rocks and add heat and pressure = Metamorphic Rocks.   Thanks, R
 
 
Have A Great Week!
