George Van Trump Richard J. Ebens Josephine G. Boerngen 1975 <p>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. &nbsp;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). &nbsp;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).</p> application/pdf 10.3133/ofr75137 en U.S. Geological Survey Analytical data for geologic units in Missouri and parts of Kansas, Oklahoma and Arkansas reports
