Abstract

"The progress of research in sedimentary petrology in Germany during the years 1936-1948 is reviewed and discussed; particular attention is paid to heavy- mineral analysis. In order to make a survey of the numerous papers a uniform one, units and terms employed have been modified where necessary; for example, all mineral frequencies have been expressed as percentages. Except in the discussion of methods and problems, the treatment is by stratigraphic units."
