Full Description

This volume grew out of a symposium held at the 27th Annual Meeting of the Clay Minerals Society in Columbia, Missouri, during October, 1990. The symposium was de­signed to present a current synthesis of research devoted to the origin, diagenesis, and petrophysics of clay minerals in sandstones. Appropriately, this meeting of the Clay Min­erals Society was held in honor of Walter D. Keller in his 90th year. Keller's pioneering work in sedimentary petrol­ogy, geochemistry, and clay mineralogy, including the ap­plication of scanning electron microscopy (e.g., Borst and Keller, 1969), has contributed much to our understanding of the origin of clay minerals in diverse rock types, in­cluding sandstones. 

The introductory paper presents a brief historical per­spective of research that has molded our understanding of clay minerals in sandstones, and provides perspective for this collection of papers, which represents current trends in research activities.
