Antarctic drilling and mapping projects are reported on. (BB)

Geologists in this field are becoming increasingly involved in studies of land use. (Author/BB)

Developments in clastic sedimentology for 1978 focused on energy, especially petroleum exploration. (BB)

The congress of the International Committee for the History of Geology held in September at Munster, West Germany, had as its theme regional influences on the history of geology. (Author/BB)

A brief summary of work completed by micropaleontologists in 1978. (BB)

Seismological research last year was directed toward several fundamental problems. Advances were made in the computation of theoretical seismograms for complex structures and sources. (BB)

Contributions to this field for 1978 are discussed. Of special interest are the jawless marine fishes that were found in marine deposits from Late Cambrian time. (BB)

Drilling during 1978 focused on three major geologic problems: the nature and origin of the oceanic crust, the nature and geologic history of the active continental margins, and the oceanic paleoenvironment. (Author/BB)

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)

Important areas of geodynamics research for the future are the thermal structure and the volatile content of the crust and upper mantle. (BB)

Research efforts tended to focus on the ancestry of major groups in 1978, and in particular on Cambrian fossils. (Author/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)
