Ab&r&-Sulphur isotope abundances of thirty-nine specimens of seventeen meteorites are reported. The resultril show again the remarkable constancy of the sulphur isotope ratios for meteorites of all types. However, differences in the SBa/Sa* ratios of 0.4 %a would appear to be significant. The Ssz/P4 ratio for meteorites is discussed as a possible base level from which fr~tion&tion in the earth’...

Yellowstone National Park plays host to numerous microbiological research projects — officially 23, according to the 1996 Investigators' Annual Reports. However, once categories such as aquatic ecology, the study of brucellosis and other wildlife diseases, environmental education, geochemistry and geothermal systems, and vegetation are included, the total came to at least 35 in 1996. Research p...

Background: We intend to study the inhibitory effect of sulfur compound in Ramsar hot spring mineral on tumor-genesis ability of high natural background radiation. Objective: The radioprotective effect of sulfur compounds was previously shown on radiation-induced chromosomal aberration, micronuclei in mouse bone marrow cells and human peripheral lymphocyte. Ramsar is known for having the highe...

This review is intended principally to be a reasonably comprehensive bibliography. It covers papers by workers in stable isotope geochemistry in the United States that have been published or presented at national meetings since the last quadrennial report. The titles of the papers in the bibliography are in most cases indicative of the general content, so only the highlights are described below...
