Road log and documentary photographs for 15 significant biostratigraphic sites in Miocene-Pliocene limestone, Kingshill Seaway, St. Croix, U.S. Virgin Islands
Detailed examination of planktonic Foraminifera from the type section of the Miocene Kingshill Limestone and from 14 other Miocene and lower Pliocene limestone exposures in the Kingshill Seaway of St. Croix ((at 17°44' N., long 64° 46' W.; fig. 1) has led to the first publication of an in-depth biostratigraphic investigation of this area with application of the most up-to-date zonation and ecologi

Proceedings of Conference XIII, evaluation of regional seismic hazards and risk
The participants in the conference concluded that a great deal of useful research has been performed in the national Earthquake Hazards Reduction
Program by USGS and non-USGS scientists and engineers and that the state-of-knowledge concerning the evaluation of seismic hazards and risk has been advanced substantially. Many of the technical issues raised during the conference are less controversial

Data file: the 1976 Atlantic Margin Coring (AMCOR) Project of the U.S. Geological Survey
In 1976, the U.S. Geological Survey conducted the Atlantic Margin Coring Project (AMCOR) to obtain information on stratigraphy, hydrology and water chemistry, mineral resources other than petroleum hydrocarbons, and geotechnical engineering properties at sites widely distributed along the Continental Shelf and Slope of the Eastern United States (Hathaway and others, 1976, 1979). This program's pri

Landslides from the February 4, 1976, Guatemala earthquake
The M (Richter magnitude) = 7.5 Guatemala earthquake of February 4, 1976, generated more than 10,000 landslides throughout an area of approximately 16,000 km2. These landslides caused hundreds of fatalities as well as extensive property damage. Landslides disrupted both highways and the railroad system and thus severely hindered early rescue efforts. In Guatemala City, extensive property damage an

Grooved terrain on Ganymede
The icy crust of Ganymede comprises bright and dark areas. Investigation of Voyager 1 and 2 images has shown that bright terrain is grooved and separates dark polygons of cratered terrain. The grooved terrain contains alternating ridges and grooves in straight and curvilinear sets, which are locally interrupted by smooth patches and swaths. Cratered terrain, where 'it occurs in small wedges and sl

Stability of sulfur slopes on Io
The mechanical properties of elemental sulfur are such that the upper crust of Io cannot be primarily sulfur. For heat flows in the range 100–1000 ergs cm−2, sec−1, sulfur becomes ductile within several hundred meters of the surface and would prevent the formation of calderas with depths greater than this. However, the one caldera for which precise depth data are available is 2 km deep, and this v

Plastic deformation of MgO(A12O2)1·1 spinel at 0·28TM preliminary results
Prism-shaped single crystals of MgO(Al2O3)n spinel (n < 1.1) have been compressed to significant plastic strain at a temperature of 400°C (∼0·28 TM) in controlled experiments under a superimposed hydrostatic pressure of 1·4 GPa. Compression of crystals approximately parallel to <001>, <111> and <011> resulted in simple yield behaviour at axial stress differences of 1940, 3720, and 4300 MPa respect

Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: September 1980
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory; therefore it should be regarded as preliminary.
