Geology of the petroleum and coal deposits in the North China basin, eastern China
K. Y. Lee
1986, Open-File Report 86-154
The North China basin evolved initially from a rifted intracratonic graben system on the east-central Sino-Korean platform during the Jurassic and Cretaceous Yanshanian orogeny. The basin reached its maximum stage of development in the Neogene owing to rift reactivation by the Himalayan orogeny. As indicated by geophysical data, extensional rifting...
Irrigated acreage and other land uses on the Snake River Plain, Idaho and eastern Oregon
Gerald F. Lindholm, S. A. Goodell
1986, Hydrologic Atlas 691
Prompted by the need for a current, accurate, and repeatable delineation of irrigated acreage on the Snake River Plain, the U.S. Geological Survey entered into a cooperative agreement with the Idaho Department of Water Resources Image Analysis Facility and the U.S. Bureau of Reclamation to delineate 1980 land use form...

Water levels, location, depths, and aquifers tapped are given for 113 observation wells in Michigan. Tabulated data include extremes of water levels for 1985 and for the period of record, pumpage of most major groundwater users in the state, and water quality data from selected wells. (USGS)...
Velocity and surface altitude of the lower part of Hubbard Glacier, Alaska, August 1978
R. M. Krimmel, W. G. Sikonia
1986, Open-File Report 86-549
The terminus position and locations of numerous points on the lower part of Hubbard Glacier were determined from 1:58,000 scale vertical aerial photographs taken July 30, 1978 and August 23, 1978. The same surface features were located on each set of photography, allowing displacement during the time interval to be...

1986, Open-File Report 86-61
Snow chemistry data were measured for solutes found in snow core samples collected from the Cascade-Sierra Nevada Mountains from late February to mid-March 1983. The data are part of a study to assess geographic variations in atmospheric deposition in Washington, Oregon, and California. The constituents and properties include pH and...

1986, Open-File Report 85-695
A bibliography for the Southern California Alluvial Basins Regional Aquifer-Systems Analysis includes references for about 3,500 publications related to the geohydrology of the 75,000 sq-mi region, which encompasses all of southern California except the Central Valley, the Channel Islands and the Pacific Ocean floor off southern California, and parts of...
Hydrologic data for urban studies in the Houston metropolitan area, Texas, 1983
Fred Liscum
1986, Open-File Report 86-487
Hydro!ogic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. Studies are now in progress in the Austin and Houston areas, and have been completed in the Dallas-Fort Worth and San Antonio areas. The U.S. Geological Survey, in cooperation with the city of Houston, began...
A preliminary evaluation of the geohydrology and water quality of the Greenacres Landfill area, Spokane County, Washington

1986, Open-File Report 85-496
The Greenacres Landfill, located about 11 mi east of the city of Spokane, Washington, was used for the disposal of waste from 1951 to 1972. Materials in the landfill include household and industrial waste materials, and various hazardous wastes. In 1983 the landfill was designated by the U.S. EPA as...

Volcanic rocks
1986, Report
Volcanoes have contributed significantly to the formation of the surface of our planet. Volcanism produced the crust we live on and most of the air we breathe. Often the remnants of an eruption are as revealing as the eruption itself, for they tell us many things about the eruption. Included...
Landslides
National Geophysical Data Center
1986, Report
The slopes above streams and rivers are subjected to a variety of processes that cause them to recede and retreat from the river or stream channel. These processes, collectively called mass wasting, can be classified according to rapidity of movement and according to the type of materials that are transported. Gravity is the...
Earthquakes
National Geophysical Data Center
1986, Report
An earthquake is the motion or trembling of the ground produced by sudden displacement of rock in the Earth's crust. Earthquakes result from crustal strain, volcanism, landslides, and collapse of caverns. Stress accumulates in response to tectonic forces until it exceeds the strength of the rock. The rock then breaks along a preexisting...

1986, Report
Section 1002 of the Alaska National Interest Lands Conservation Act of 1980 (ANILCA, 1980) requires the Secretary of Interior to conduct a continuing study of fish, wildlife, and habitats on the coastal plain of the Arctic National Wildlife Refuge (ANWR). Included in this study is a determination of the extent, location, and carrying capacity of...
On tide-induced Lagrangian residual current and residual transport: 1. Lagrangian residual current
Shizuo Feng, Ralph T. Cheng, Xi Pangen
1986, Water Resources Research (22) 1623-1634
Residual currents in tidal estuaries and coastal embayments have been recognized as fundamental factors which affect the long-term transport processes. It has been pointed out by previous studies that it is more relevant to use a Lagrangian mean velocity than an Eulerian mean velocity to determine the movements of water...
On tide-induced Lagrangian residual current and residual transport: 2. Residual transport with application in south San Francisco Bay, California
Shizuo Feng, Ralph T. Cheng, Xi Pangen
1986, Water Resources Research (22) 1635-1646
The transports of solutes and other tracers are fundamental to estuarine processes. The apparent transport mechanisms are convection by tidal current and current-induced shear effect dispersion for processes which take place in a time period of the order of a tidal cycle. However, as emphasis is shifted toward the effects...
Evaluation of Alaskan wetlands for waterfowl
Calvin J. Lensink, Dirk V. Derksen
1986, Conference Paper, Alaska: Regional wetland functions: Proceedings of a workshop held at Anchorage, Alaska, May 28-29, 1986
Few studies have focused specifically on use of Alaskan wetlands by waterfowl. However, substantial information on the values of wetlands is available from studies on individual species or that were conducted for other purposes. Most investigators have found it most effective to classify habitat use on the basis of observed...
