1972, Report
The U.S. Geological Survey collected 110 water samples from Amchitka Island, Alaska, between January 13 and April 5, 1972. Tritium determinations were made on all samples collected and gross alpha and gross beta/gamma determinations were made on 92 samples. The gross alpha and gross beta determinations when compared with previously...

1972, Wisconsin Geological & Natural History Survey Information Circular 21
This report supplements the Wisconsin Geological and Natural History Survey, Information Circular No.9, "Trends in Ground-Water Levels in Wisconsin through 1966". It describes, by hydrographs, the ground-water level trends in Wisconsin for the period 1967-1971. All current observation wells with more than three years of record are included; records of...

1972, Wisconsin Geological & Natural History Survey Information Circular 22
Ground water, a plentiful and largely underdeveloped resource of Wisconsin, has good to excellent chemical quality in most places. This resource is readily available in most parts of the State for municipal, industrial, and rural uses. In 1970, about 0.5 billion gallons of ground water a day was pumped in...

Lehigh County occupies an area of 347 square miles in southeastern Pennsylvania. The northern part of Lehigh County is underlain by the Martinsburg Formation, which consists chiefly of shale and slate. The central part of the county, where most of the population centers are located and much of the urbanization...

The Martinsburg Formation underlies the northern half of Lehigh and Northampton Counties, and is of Middle and LateOrdovician age. It is bounded on the south by older Ordovician limestone formations and on the north by a ridge-forming conglomerate of Silurian age. Recent mapping has supported a three-part division of the...

Four evaporite-bearing stratigraphic zones are known in Cretaceous strata of the Cordillera Oriental of Colombia north and east of Bogota. The easternmost and oldest zone is probably of Berriasian to Valanginian age. The next oldest is probably late Barremian to early Aptian in age. The third appears to be Aptian....

A geochemical exploration program aimed at determining regional patterns of metal distribution as well as pinpointing areas likely to contain undiscovered ore deposits was carried out in north-central Okanogan County, Washington. About 1,000 gully and stream sediment samples were collected from a rectangular area of about 800 square miles. The...

1972, Report
Observed gravity values, station location, terrain corrections, and Bouguer gravity data are provided in tabular form for approximately 610 gravity observations in northern Arizona. These data were used in preparation of - - Popenoe, Peter, 1968, Complete Bouguer gravity anomaly map of the area north of the Grand Canyon in...

1972, Book chapter, Apollo 15 preliminary science report (NASA SP-289)
Approximately 35 reasonably good candidates for specialized photometric studies were found during a thorough examination of the frames exposed by the Apollo 15 metric camera. Of these, the majority was of value in heiligenschein studies (refs. 25-36 to 25-38). A few were of value for limited-interval delineation of the photometric...
