David K. Webb is placing a powdered (finely ground) sample into an x-ray diffractometer to identify minerals. David was an expert on clay mineralogy and was probably using the diffractometer to identify mineralogy of clays found in Ohio. Examples of clay minerals commonly found in Ohio are kaolinite, illite, montmorillonite and chlorite. David worked in the Regional Geology Section of the Ohio Geological Survey and was also Assistant Chief of the division. This picture was taken in the geochemistry laboratory at the Grandview Avenue Offices. The image was taken in 1971.
The Ohio Department of Natural Resources, Division of Geological Survey's main office was located at 1207 Grandview Avenue, Grandview Heights, Ohio 43212 from 1962 through May 1973. The Geological Survey's offices were on part of the first floor and all of the second floor of the building. The Grandview office had x-ray, petrography, and geochemistry laboratories on the first floor. More informally, rooms with coal polishing equipment, microscopes, and other types of equipment were located in various spaces at the Grandview office.
Information about the history of the Survey's facilities is available in Survey Opens New Core and Sample Repository by Merrianne Hackathorn (Ohio Geological Survey, Ohio Geology Newsletter, No. 4, 1999).
