Shallow marine Paleogene carbonates of the Eastern Gulf Coastal Plain contain a variety of unique and largely undocumented facies. The Late Paleocene Salt Mountain Limestone of southwestern Alabama is a coral-algal-sponge buildup composed of large foram-algal packstone, algal bindstone, and sponge-coral bafflestone. Abundant coralline algae and a low diversity coral fauna are characteristic of Paleocene reefs, but sponges are rare in earliest Tertiary sediments. Their abundance in the Salt Mountain could indicate an opportunistic response of sponges as reef constructors after the extinction of rudist-coral communities in the Late Cretaceous.
The Bridgeboro Limestone, a rhodolith and coral-bearing limestone in southwestern …

Masters Theses
Understanding the geology of any region begins with the construction of high-quality geologic maps. As maps for a specific region are revised in greater detail, geologic understanding is improved. This study involved detailed geologic mapping (at the scale of 1 : 24,000) of a portion of the southern Appalachian Blue Ridge that was previously only mapped by reconnaissance. It is hoped that the research herein will add to the present understanding of the Blue Ridge province and of the entire Appalachian orogenic belt.
During the course of field mapping, three lithotectonic units were divided, each separated from the others by …
