Mapping Phyllic and Argillic-Altered Rocks in Southeastern Afghanistan using Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Data
John L. Mars, Lawrence C. Rowan
2007, Open-File Report 2007-1006
Introduction: ASTER data and logical operators were successfully used to map phyllic and argillic-altered rocks in the southeastern part of Afghanistan. Hyperion data were used to correct ASTER band 5 and ASTER data were georegistered to orthorectified Landsat TM data. Logical operator algorithms produced argillic and phyllic byte ASTER images...

Peak stages from backwater conditions at streamflow-gaging stations in and near South Dakota through water year 2001
Ryan F. Thompson
2007, Open-File Report 2006-1395
Stream stages associated with the annual peak discharge are presented for 182 streamflow-gaging stations in and near South Dakota. The peak stage at a station can occur as the result of the annual maximum discharge, but also as the result of backwater conditions. Backwater, often caused by ice, can produce...

2007, Open-File Report 2007-1047-SRP-026
Glacial sequences deposited on the base-of-slope and upper continental rise off the eastern Wilkes Land margin show that depositional systems vary with time. During the early Oligocene to middle-late Miocene times glacial sequences are dominated by extensive glacigenic debris flow deposits (GDFs) that have lens or wedge shaped external geometries and internal chaotic...

M.J. Flowerdew, J.S. Daly, T.R. Riley
2007, Open-File Report 2007-1047-SRP-012
Five of six Rb-Sr muscovite mineral isochron ages from the Scotia Metamorphic Complex of the South Orkney Islands, West Antarctica, average 190 ± 4 Ma. The muscovite ages are interpreted to date foliation-formation and thus also accretion and subduction at the Gondwana margin. Coincident picrite and ferropicrite magmatism, indicative of...
