June 19, 2016 Weekly Geology Guess

June 19, 2016
Note 1:  I was out of town last week with two of my sons, Paul with his dog – Vallerie, and Phillip.  We went to Cartersville, GA to the Tellus Science Museum for their annual Gem and Mineral Show.  Sorry, I didn’t bring back any solid gold goodies —- This Time.
Tellus Museum is a must visit place if you like geology.  They have a world class mineral and fossil collection along with other collections, and entertainment for the youngsters > Science Projects, Gem Mining, and I think gold panning.
>    On June 8, I received a “Lifetime Achievement Award” from the Alabama Soil and Water Conservation Society.
Thanks to the members of the AL SWCS.

Greetings from the Bluff Park   Porch, way up yonder on Shades Mountain (1,109′) in Alabama:
My discussion on Alabama Geology will continue with the with the Alabama Coastal Plain.


Minerals and Rocks – The Good Life from the Ground

Alabama Coastal Plain

East Gulf Coastal Plain:  The broad, flat coastal plain stretches across the southern portion of the state, extending north from the Gulf coast to the fall line near Montgomery, Alabama.”
The East Gulf Coastal Plain section is an area of Mesozoic and Cenozoic sediments that occupies the southern part of the state and curves northwesterly up into Lauderdale County, where generally unconsolidated sediments overlap rocks of the Highland Rim, Cumberland Plateau, Valley and Ridge, and Piedmont Upland sections. – See more at:
Odds and Ends
“A cuesta is the term used to describe a hill or ridge with a gentle slope on one side, and a steep slope on the other. In geology the term is more specifically applied to a ridge where a harder sedimentary rock overlies a softer layer, the whole being tilted somewhat from the horizontal. This results in a long and gentle backslope called a dip slope that conforms with the dip of resistant strata, called caprock.”  Wikipedia

Another meteor impact that supposedly wiped out the dinosaurs at the Cretaceous-Tertiary Boundry from the Chicxulub Impact, generated a huge tsunami that impacted the shallow seas and devastated the Alabama Gulf shoreline, as it existed at that time.  Microtektites and other geologic evidence have been found at Moscow Landing on the Tombigbee River in Sumter County, another at Shell Creek in Wilcox County, and a third at Mussel Creek in Butler County.
Tektites (from Greek τηκτός tēktós, “molten”) are gravel-size bodies composed of black, green, brown or gray natural glass formed from terrestrial debris ejected during extraterrestrial, meteorite impacts. They generally range in size from millimeters to centimeters. Millimeters-size tektites are known as microtektites.[1][2][3]

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 expand our Alabama Geology Search to include sinkholes and caves, and maybe earthquakes, if I don’t run out of room
