Interagency field manual for the collection of water-quality data
2000, Open-File Report 2000-213
Along the United States-Mexico border region, numerous Federal, State, and local agencies; nongovernmental organizations (NGO); and researchers collect water-quality data for many purposes. The water community uses a number of documented and undocumented procedures, some of which have specific data-quality objectives (DQO) and data-information objectives. This mix of procedures results...

This geologic map represents a compilation of mostly previously unpublished maps by numerous authors. The map is divided into three areas of responsibility: 1) the Tendoy Mountains and western Centennial Mountains, mapped and compiled by Betty Skipp, Susanne Janecke, and Bill Perry (Part A); 2) the Snowcrest Range, mapped by...
Analytical results and sample locality map for rock, stream-sediment, and soil samples, Northern and Eastern Colorado Desert BLM Resource Area, Imperial, Riverside, and San Bernardino Counties, California
Harley D. King, Maurice A. Chaffee
2000, Open-File Report 2000-105-B
In 1996-1998 the U.S. Geological Survey (USGS) conducted a geochemical study of the Bureau of Land Management's (BLM) 5.5 million-acre Northern and Eastern Colorado Desert Resource Area (usually referred to as the NECD in this report), Imperial, Riverside, and San Bernardino Counties, southeastern California (figure 1). This study was done...
The North Sakhalin Neogene total petroleum system of eastern Russia
S.J. Lindquist
2000, Open-File Report 99-50-O
The North Sakhalin Basin Province of eastern Russia contains one Total Petroleum System (TPS) ? North Sakhalin Neogene ? with more than 6 BBOE known, ultimately recoverable petroleum (61% gas, 36% oil, 3% condensate). Tertiary rocks in the basin were deposited by the prograding paleo-Amur River system. Marine to continental,...
