Report of research on the Carolina slate belt and gold deposits in Virginia, North Carolina, South Carolina, and Georgia with geologic mapping, mineralogic, geochemical, and fluid evolution studies, radiogenic dating, and stable isotope studies.
Overview of the Core Research Center (CRC) in Denver for preserving valuable rock cores for permanent storage and making the cores available for examination and testing. Includes links to services, well reports, and resources.
Explains the important paleoclimatic information we have obtained from this subaqueous cavern. The time-series data show important contrasts with what would be predicted from orbital theory, provoking extensive scientific discussion.
Revised geologic time scale indicating the ages of the lower bounds of chronostratigraphic and geochronologic units as they are currently known. Modifications to those ages made since the previous time scale was released (2007) are clearly marked.
Publication (PDF format) in three parts on the biostratigraphy and lithostratigraphy of the Ibexian Series in the North American Ordovician, with sections on the southern Egan Range, Nevada and the biostratigraphy of the eastern Great Basin.
