Requests and invitations

It was the same show, but this time it was playing in the right house. Requests and invitations poured upon her from oil companies wherever they might be, and from geological societies situated in oil centers like Calgary and Tulsa. “It filled a big hole in their technology,” Anita has said, recalling those days. “They have to be able to assess the thermal level of deposits, and this was a simple way to do it.” Anita became a conodont specialist for the United States Geological Survey, full time. She lives in Maryland. Her home is an island in flower beds and lawn. She gets up at four-thirty and drives to work at the Survey’s headquarters in Reston, Virginia. Oil companies have continued to beat the path to her door, as have oil geologists from every continent but Antarctica, including large delegations from the Chinese Geological Survey. While oil prospectors are using brown and yellow conodonts to guide them to the flexplek huren rotterdam thermal window, mineral prospectors are using white ones in the search for copper, iron, silver, and gold. White conodonts and clear conodonts, products of the highest temperatures, suggest the remains of thermal hot spots, thermal aureoles, ancient hydrothermal springs-places where metallic minerals would have come up in solution to be precipitated out into veins. Soon after her discovery, universities began calling her. She was pleased to appear at places like Princeton, pleased to be given an opportunity to demonstrate what could be learned elsewhere. Women students were in her audience now. In the late nineteenseventies, she and her colleagues published a succession of scientific papers whose title pages perforce encapsulated not only their professional endeavors but something of their private lives. The “senior author” of a scientific publication is the person whose name is listed first and whose work has been of primary importance to the project, while other authors are listed more or less in diminishing order, like the ingredients on a can of stew. The benchmark paper came in i977. Entitled “Conodont Colar Alteration-an Index to Organic Metamorphism,” it was “by Anita G. Epstein, Jack B. Epstein, and Leonard D. Harris.” Then, in i978, came “Oil and Gas flexplek huren amsterdam Data from Paleozoic Rocks in the Appalachian Basin: Maps for Assessing Hydrocarbon Potential and Thermal Maturity (Conodont Colar Alteration Isograds and Overburden Isopachs)”- virtually an oil-prospecting kit, a highly specialized atlas-“by Anita G. Harris, Leonard D. Harris, and Jack B. Epstein.” And scarcely a year after that appeared a summary document called “Conodont Colar Alteration, an Organo-Mineral Metamorphic Index, and Its Application to Appalachian Basin Geology”-“by Anita G. Harris.”
