Professor, Geology; College of Arts & Sciences
Warren received his PhD from the University of Cincinnati in 1963 and has been a faculty member here since that time. Much of his research deals with the study of bentonites and K-bentonites, which are the remains of explosively erupted volcanic ash layers. These layers are now altered largely to clay minerals, although some original volcanic crystals remain. Dr. Huff studies both types of minerals to learn about the nature of the source volcanoes, many of which are several hundreds of millions years old, as well as the natural processes by which the volcanic ash layers have been buried in the earth and altered to their present form.
