Calculated volumes of individual shield volcanoes along the Hawaiian-Emperor chain

Volume was calculated for the 107 individual volcanic shields along the Hawaiian Ridge Emperor Seamounts chain to help fulfill the need for volume data essential to determining eruption rates, fraction of mantle melted, and other parameters. Boundaries used were based principally upon location of rift zones related to each shield. Volcanic loci shown are modified from an earlier map to accommodate changes in bathymetry. Total volumes calculated for the Emperor and Hawaiian chains are 336.3 X 10 3 km 3 and 744.9 X 10 3 km 3

Preliminary textures and mineral associations in the ultramafic zone of the Stillwater complex, Montana

This paper presents some results of work done between 1951 and 1955 as a part of a comprehensive investigation of the stratigraphy, geochemistry, and petrography of the Ultramafic zone of the Stillwater complex by the U. S. Geological Survey. Detailed mapping of the chromite deposits of the complex was done between 1939 and 1943, under the supervision of J. W. Peoples. Reports of this work, and geologic maps of most of the complex, have been published: Peoples and Howland (1940); Wimmler (1948); Howland, Garrels, and Jones (1949); Peoples, Howland, Jones, and Flint (1954); Jackson, Howland, Peoples, and Jones (1954); Howland (1955); Jones, Peoples, and Howland (in press). The present investigation has called for additional mapping and study of many problems which had to be bypassed because of the pressure of wartime urgency. I spent a total of about 15 months in the field during the summers of 1951 through 1955; P. R. Vail assisted in the field work in 1952 and 1953, and R. L. Christiansen assisted in 1954.
