Enumerates some of the research findings in geochemistry during the last year, including X-ray analysis of the Mars surface, trace analysis of fresh and esterarine waters, and analysis of marine sedements. (MLH)

The growing interest in evaporite geology in 1978 is shown by the number of short courses, meetings, and symposiums that were held on various aspects of evaporites. (BB)

Developments in this field during 1978 included four major meetings, two treatises on copper, one on arsenic, an assessment of mercury, and a book on "Modern Methods of Trace Element Analysis." (BB)

Discusses advancements in trace-element analyses related to health and disease, earth science, and physiological processes. (MLH)

Research in carbonate geology over the last year continued many trends prevalent the year before, not the least of which has been the study of modern carbonate platform margins. (Author/BB)

Techniques in geochemistry continue to improve in sensitivity and scope. The exciting areas of geochemistry still include the classical fields of the origin of the elements and objects in space, but environmental crisis problems are important as well. (Author/BB)

Reviews research in carbonate geology focusing on both sedimentology and diagenesis of shallow and deep water carbonates. (MA)

The past year has seen the development of certain fields of geochemical research including Nd-Sm isotope studies of meteorites and ancient terrestrial rocks; the use of the consortium approach of assembling a multidisciplined team to tackle a problem; and the handling and analysis of small quantities of materials. (Author/MA)

Contributions in mineral-deposit model formulation, geochemical exploration in glaciated and arid environments, analytical and sampling problems, and bibliographic research were made in symposia held and proceedings volumes published during 1982. Highlights of these symposia and proceedings and comments on trends in exploration geochemistry are…

Mineralogy has become increasingly linked to chemistry and physics during recent years. This relationship between chemistry, physics, and mineralogy, as indicated by the content of conference papers, research studies, and physical/chemical laboratory procedures used in mineralogy, is reviewed. Creative applications of established mineralogic…
