Radiometric calibration status of Landsat-7 and Landsat-5
Julia A. Barsi, Brian L. Markham, Dennis Helder, Gyanesh Chander
2007, Conference Paper
Launched in April 1999, Landsat-7 ETM+ continues to acquire data globally. The Scan Line Corrector in failure in 2003 has affected ground coverage and the recent switch to Bumper Mode operations in April 2007 has degraded the internal geometric accuracy of the data, but the radiometry has been unaffected. The...
Comparative deformation behavior of minerals in serpentinized ultramafic rock: Application to the slab-mantle interface in subduction zones
Diane E. Moore, David A. Lockner
2007, International Geology Review (49) 401-415
The layer-structure minerals serpentine, brucite, and talc are postulated to form in the mantle wedge above a subducting slab as a result of progressive hydration and silica metasomatism. Tectonic mixing at the slab-mantle interface generates serpentinite mélanges that contain blocks of high-pressure (HP) or ultrahigh-pressure (UHP) metamorphic rock derived...

From Projectile Points to Microprocessors - The Influence of Some Industrial Minerals
Rhonda Driscoll
2007, Circular 1314
In the language of economic geology, Earth materials are classified as metallic ores, fuel minerals, gemstones, and industrial minerals. Most people know that metallic ores yield shiny, conductive, ductile elements such as copper, iron, or gold. Most understand that energy-producing coals constitute a fuel mineral. Likewise, dazzling rubies and rare...

Bankfull Regional Curves for Streams in the Non-Urban, Non-Tidal Coastal Plain Physiographic Province, Virginia and Maryland
Jennifer L. Krstolic, Jeffrey J. Chaplin
2007, Scientific Investigations Report 2007-5162
Natural-channel design involves constructing a stream channel with the dimensions, slope, and plan-view pattern that would be expected to transport water and sediment and yet maintain habitat and aesthetics consistent with unimpaired reaches. The adequate description of channel geometry in unimpaired reaches often is an important component of natural-channel design...
Age Determination of the Remaining Peat in the Sacramento-San Joaquin Delta, California, USA
Judith Z. Drexler, Christian S. de Fontaine, Donna L. Knifong
2007, Open-File Report 2007-1303
Introduction The Sacramento-San Joaquin Delta of California was once a 1,400 square kilometer (km2) tidal marsh, which contained a vast layer of peat ranging up to 15 meters (m) thick (Atwater and Belknap, 1980). Because of its favorable climate and highly fertile peat soils, the majority of the Delta was drained...
