Overview of the Strategic and Structural Evolution of the Talladega Slate Belt, Alabama Appalachians
fl d029-08 1st pgs page 1 The Geological Society of America Field Guide 29 2012 Overview of the stratigraphic and structural evolution of the Talladega slate belt, Alabama Appalachians James F. Tull* Department of Earth, Ocean, and Atmospheric Science, Florida State University Clinton I. Barineau* Department of Earth and Space Sciences, Columbus State University ABSTRACT The allochthonous Talladega belt of eastern-northeastern Alabama and north- western Georgia is a northeast striking, fault bounded block of lower greenschist facies metasedimentary and metaigneous rocks that formed along the margin of Lau- rentia at or outboard of the seaward edge of the Alabama promontory. Bounded by metamorphic rocks of the higher grade Neoproterozoic(?) to Carboniferous eastern Blue Ridge on the southeast and unmetamorphosed to anchimetamorphic Paleozoic rocks of the Appalachian foreland on the northwest, the Talladega belt includes shelf facies rocks of the latest Neoproterozoic/earliest Cambrian Kahatchee Mountain Group, Cambrian-Ordovician Sylacauga Marble Group, and the latest Silurian(?) to uppermost Devonian/earliest Mississippian Talladega Group. Along the southeast- ern fl ank of these metasedimentary sequences, a Middle Ordovician back-arc terrane (Hillabee Greenstone) was tectonically emplaced along a cryptic pre-metamorphic thrust fault (Hillabee thrust) and subsequently dismembered with units of the upper Talladega Group along the post-metamorphic Hollins Line fault system. Importantly, strata within the Talladega belt are critical for understanding the tectonic evolution of the southern Appalachian orogen when coupled with the geologic history of adjacent terranes. Rocks of the lower Talladega Group, the Lay Dam Formation, suggest latest Silurian-earliest Devonian tectonism that is only now being recognized in other areas of the southern Appalachians. -

A ~rCF~T visit to the Southern States of North America induces me to lay before the Society some observations on the physical aspect of a peculiarly interesting region traversed by the Tennessee River in the State of the same name and the bordering districts. The geological structure of this district has been ably described by Professor James :M. Safford, the State Geologist *. The region is now in process of being re-surveyed topographically and geologically under the direc- tion of Major Powell, U.S. Geological Survey, to whom I am much indebted ibr kind assistance in procuring maps and informa- tion t. -
