Comparison of flank margin cave development on San Salvador island, Bahamas, and Isla de Mona, Puerto Rico Comparison of flank margin cave development on San Salvador island, Bahamas, and Isla de Mona, Puerto Rico
San Salvador Island, Bahamas is a 161 Km2 tectonically stable late Quaternary carbonate island located 600 km east-southeast of Miami FL. San Salvador contains numerous flank margin caves (phreatic karst features) that developed primarily in late Pleistocene eolianites. These caves developed during a short time in versy small fresh-water lenses. Cave elevations and Uranium-series ages...

Pesticides detected in surface waters and fish of the Red River of the North drainage basin Pesticides detected in surface waters and fish of the Red River of the North drainage basin
The Red River of the North drainage basin (herein referred to as Red River Basin) within the United States is a study unit under the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) program. The overall goals of this program, initiated to better define the status and trends of the Nation’s water quality, are to address regional and national water-quality issues in...

Tertiary structural evolution of the southern Rhodope metamorphic province: a fundamental revision Tertiary structural evolution of the southern Rhodope metamorphic province: a fundamental revision
The Rhodope province is conventionally interpreted as a continental fragment that was caught between Apulia and Europe and deformed and metamorphosed in the hinterland of the Hellenic collisional orogen. Geologic mapping in the Strymon Valley region of northeastern Greece augmented by new U-Pb and 40Ar/ 39Ar geochronologic data support an alternative view that the southwestern Rhodope...
