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...

Paul F. Juckem
2007, Scientific Investigations Report 2007-5112
Population growth in the St. Croix River Basin in Minnesota and Wisconsin has intensified concerns of county resource managers and the National Park Service, which is charged with protecting the St. Croix National Scenic Riverway, about the potential for ground-water contamination in the basin. This report describes a previously...
Geologic Map of Part of the Western Hellas Planitia, Mars
Jeffrey M. Moore, Don E. Wilhelms
2007, Scientific Investigations Map 2953
Introduction Rock units were deposited on Mars by meteorite impact, volcanism, wind, flowing water, standing water, and ice, acting separately or in concert. Hellas Planitia, the deepest tract on Mars, is a broad depression lying within the high-rimmed, approximately 2,300-km-wide Hellas impact basin. The basin and the planitia are centered about...

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...

Regionalized equations for bankfull discharge and channel characteristics of streams in New York State — Hydrologic Regions 1 and 2 in the Adirondack Region of northern New York
Christiane I. Mulvihill, Amy Filopowicz, Arthur Coleman, Barry P. Baldigo
2007, Scientific Investigations Report 2007-5189
Equations that relate drainage area to bankfull discharge and channel characteristics (width, depth, and cross-sectional area) at gaged sites are needed to define bankfull-discharge and channel characteristics at ungaged sites and to provide information for watershed assessments, stream-channel classification, and design of stream-restoration projects. Such equations are most accurate if...

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...
