The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States in the United States (Algermissen, 1969) which have been recompiled and updated through 1977. These data have been reexamined...
Map showing paleontological control of Paleozoic stratigraphy in New England
Marland P. Billings, Peter T. Lyttle
1981, Miscellaneous Field Studies Map 1302
Assignment of Phanerozoic stratigraphic units to their proper place in the geologica time scale is based primarily on paleontology. Radiometric methods are becoming increasingly important (Naylor, 1976), particularly where paleontological data are lacking. This map and text are concerned only with the paleontological data bearing on the Paleozoic stratigraphy of...
Map showing reconnaissance geochemistry in the gold-pyrophyllite belt of northwestern Moore County, North Carolina

1981, Miscellaneous Field Studies Map 1301
Traces of gold and molybdenum are widely disseminated in an area approximately 35 km long and 10 km wide in northwestern Moore County, N.C. At least 2540 oz. of gold were recovered from 16 or more mines and prospects between 1880 and 1910. One hundred and ninety rock samples out...

Interpretation of an aerial radiometric survey of the San Gorgonio Wilderness Area and vicinity, San Bernardino County, California
James A. Pitkin, Joseph S. Duval
1981, Miscellaneous Field Studies Map 1161-B
The aerial radiometric data for the San Gorgonio Wilderness Area show slight correlation with mapped geology and contain no information of economic significance. Precambrian and modified Precambrian crystalline rocks have more eTh compared to Mesozoic plutonic rocks and one rock unit mapped as a pluton has slightly more K. These...

The aeromagnetic map consists of parts of two surveys flown at an altitude of 300 m above the average ground surface. One survey (west park of the map_ centered over the Mokelumne Wilderness was flowing in a northeast-southwest direction along slight lines spaced at a horizontal interval of about 800...

Appearance and distribution of the gas hydrate reflection in the Blake Ridge region, offshore southeastern United States
Charles K. Paull, William P. Dillon
1981, Miscellaneous Field Studies Map 1252
A strong reflection parallel to the sea floor has been observed in seismic-reflection profiles in the Blake Ridge area off the southeastern United States. This reflection occurs at a subbottom depth of 400 to 700 m, in water depths of 750 to 3750 m. Because the reflection parallels the sea...
