Advisor: Waldorf V. Howard, Geology Department. Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 1936. Includes bibliographical references. This thesis is a study of outcropping limestones and sandstones that contain solid, semi-solid, or liquid bitumens. These deposits were studied with particular reference to the exact nature of the occurrence of the bitumen and its relation to the lithology, texture and structure of the containing rock ... The purpose of this thesis is to obtain information ... that will contribue to our knowledge of petroleum reservoirs, with particular reference to the nature of porosity and to the broader problem of petroleum origin.
