Geology of the Farmville Metagranite and Associated Units as Exposed at the Notasulga Quarry, Notasulga, Alabama
(2009-07-21)
Predicting the locations and thicknesses of aggregate-affable lithologies (ore units), interburden (non-ore material between ore-units), and overburden (overlying soil/saprolite) on a local level is critical for developing ...
Permian to Cretaceous Evolution of the Piedmont Along the Alabama - Georgia Coastal Plain Unconformity
(2009-05-07)
The Piedmont of Alabama and Georgia contains the southernmost exposure of crystalline rocks related to the culmination of accreted terranes associated with the formation of the Appalachian Mountain system. This area is ...
Hydrology and Water Chemistry in Weeks Bay, Alabama: Implications for Mercury Bioaccumulation
(2008-09-09)
Recent studies within Weeks Bay, an estuary of Mobile Bay, have revealed that both water and fish are contaminated by mercury (Hg), an element known to be extremely toxic to wildlife and humans. Seasonal variations of ...
Biotic Composition and Taphonomy of an Upper Cretaceous Konservat-Lagerstätte: The Ingersoll Shale, Eutaw Formation, Eastern Alabama
(2008-09-09)
The Ingersoll shale is a thin (<1m), laterally restricted clay lens within the Upper Cretaceous (Santonian) Eutaw Formation, Russell County, eastern Alabama. The clay lens represents abandoned tidal creek fill within an ...
Mineralogical and geochemical profiling of arsenic-contaminated alluvial aquifers in the Ganges-Brahmaputra floodplain Manikganj, Bangladesh
(2008-09-09)
The present study investigated three major components – groundwater, sediment and minerals of arsenic-affected Quaternary alluvial aquifers in Manikganj town, which is located in one of the As-hotspots in central Bangladesh. ...
Sorption of Arsenic by Iron Sulfide Made by Sulfate-reducing Bacteria: Implications for Bioremediation
(2008-09-09)
In this study, data from field bioremediation experiments, geochemical modeling, and laboratory batch experiments were integrated with published data on arsenic (As) sorption and coprecipitation onto growing iron (Fe)-sulfide ...
Provenance of Lower Pennsylvanian Pottsville Formation, Cahaba Basin, Alabama
(2008-09-09)
The Cahaba basin, also known as the Cahaba Synclinorium, of north-central Alabama contains a thick (>2.5 km) synorogenic clastic wedge belonging to the Lower Pennsylvanian Pottsville Formation. Sediment composition and ...
Stratigraphic and Paleoenvironmental Context of the Ingersoll Shale, An Upper Cretaceous Conservation Lagerstatte, Eutaw Formation, Eastern Alabama
(2008-09-09)
The Ingersoll shale, a thin (<1 m) clay-dominated lens within the Upper Cretaceous Eutaw Formation exposed in Russell County, Alabama, contains an exceptionally well-preserved, primarily terrestrial biota that includes a ...
Sedimentation and Tectonic Evolution of Cenozoic Sequences from Bengal and Assam Foreland Basins, Eastern Himalayas
(2008-09-09)
The Himalayan Mountains developed due to the collision of the Indian and Eurasian plates. There are two large foreland basins south of the eastern Himalayas: Assam Basin, located near the eastern syntaxis of the Himalayas, ...
Using Microtremors to Assess Site Characteristics in the New Madrid Seismic Zone
(2008-09-09)
Results are presented from a study in the New Madrid seismic zone (NMSZ) utilizing the microtremor method. The study analyzes and interprets horizontal to vertical (H/V) spectral ratios to determine resonant periods, wave ...
