Mineralogy of drill cores from Jabal Sa'id, Kingdom of Saudi Arabia
M.H. Staatz, I. K. Brownfield
1985, Open-File Report 85-12
The mineralogy of three drill cores from the apogranite at Jabal Sa'id was determined principally to identify those minerals containing rare earths, niobium, tantalum, thorium, zirconium, and tin. Heavy mineral studies of two other drill cores indicate that the deposit is enriched in rare earths. The principal rare earth minerals...
Map showing gravel-bearing surficial deposits and basaltic rocks near Trinidad, Las Animas County, Colorado
Glenn R. Scott
1985, Miscellaneous Field Studies Map 1738
This map of the Trinidad area is considered to be a special purpose map, as it shows only gravel-bearing alluvial deposits laid down by streams and a series of stacked lava flows erupted from local volcanoes. Nongravelly surficial deposits and Cretaceous bedrock, which would be on a standard geologic map,...

Potentiometric surface of the upper Floridan Aquifer in central Sumter County, Florida, May 1985
L. A. Bradner
1985, Open-File Report 85-551
This map presents the potentiometric surface of the Floridan aquifer system in central Sumter County, Florida, for May 1985. The Floridan aquifer system is the principal source of portable water in the area. The focus of the map is the potentiometric surface in the Jumper Creek Canal area. Water-level measurements...

Simulation of an aquifer test on the Tesuque Pueblo Grant, New Mexico
Glenn A. Hearne
1985, Water Supply Paper 2206
An aquifer test was designed and conducted in the anisotropic dipping beds of the Tesuque Formation on the Tesuque Pueblo Grant, New Mexico. The three-dimensional digital model used to analyze the test approximated the response to the test. The analysis of the geohydrology of the test site in combination with...

Geohydrology and ground-water flow at Verona Well Field, Battle Creek, Michigan
N.G. Grannemann, F. R. Twenter
1985, Water-Resources Investigations Report 85-4056
The city of Battle Creek has 30 wells in the Verona well field capable of yielding 300 to 1,000 gallons per minute each. During summer, total withdrawals are as little as 6,000 gallons per minute. In early 1984, only 9 to 12 of the wells were being used; the remaining...
Map showing Tertiary stratigraphy and structure of the Northern San Joaquin Valley, California
J. A. Bartow
1985, Miscellaneous Field Studies Map 1761
This report is a result of recent studies of the Cenozoic stratigraphy and structure of the San Joaquin Valley that were directed at Cenozoic depositional and tectonic history. Most previous work on the Cenozoic has focused on the Quaternary surficial deposits and on the outcrops of older rocks at the...

1985, Miscellaneous Field Studies Map 1751
This report presents results of a high-resolution seismic-reflection survey conducted by the U.S. Geological Survey to determine the subbottom characteristics of Penobscot Bay, Maine. Penobscot Bay is one of the major embayments along the U.S. Atlantic coast (fig. 1), extending more than 50 km from the Gulf of Maine to...

Validity of Darcy's law under transient conditions
C.E. Mongan
1985, Professional Paper 1331
Darcy 's Law, which describes fluid flow through porous materials, was developed for steady flow conditions. The validity of applying this law to transient flows has been mathematically verified for most ground-water flow conditions. The verification was accomplished through application of Hankel transforms to linearized Navier-Stokes equations which described flow...
