1983, Open-File Report 83-324
Bulk chemical analyses are performed for major and minor elements using a variety of techniques on a suite of 9 samples of sea floor massive sulfide deposits from 21?N EPR, Juan de Fuca Ridge and Galapagos Rift. Results indicate that deposits at 21?N and Juan de Fuca are very similar...
Precision gravity networks at Lassen Peak and Mount Shasta, California
Robert C. Jachens, Daniel Dzurisin, W.P. Elder, R. W. Saltus
1983, Open-File Report 83-192
Reoccupiable precision gravity networks for the purpose of monitoring volcanic activity were established in the vicinity of Lassen Peak and Mt. Shasta. Base-line measurements were made during the summer of 1981, nearly coincident in time with other base-line geodetic measurements. The gravity surveys yielded gravity values at network stations relative...
Eruptive history of the Dieng Mountains region, central Java, and potential hazards from future eruptions
C. Dan Miller, R. Sushyar, Santoso, S. Hamidi
1983, Open-File Report 83-68
The Dieng Mountains region consists of a complex of late Quaternary to recent volcanic stratocones, parasitic vents, and explosion craters. Six age groups of volcanic centers, eruptive products, and explosion craters are recognized in the region based on their morphology, degree of dissection, stratigraphic relationships, and degree of weathering. These...
