This report lists the geochemical data collected during the course of a reconnaissance study of compositional variation in the bedrock and surficial gelogic untis exposed in Missouri and adjoining parts of Kansas, Oklahoma, and Arkansas. The primar object of the study was to assess scale-related components of geochemical variance with a view of determining the importance of regional geochemical variation in these units (cf. Connor and other, 1972). Geologic evaluation, geochemical interpretation and summaries, and sampling designs employed in the collection of most of these data may be found in U.S. Geological Survey (1972a-1972f, 1973) and Connor and Shacklette (1975).
