Front-rank geologists

There were new positions for about two hundred front-rank geologists. They were hired away from oil companies or brought in from elsewhere in the Survey. What attracted the people from the companies was the opportunity to do publishable research. To run the branch, Peter R. Rose gave up his position as a staff geologist of Shell. Leonard Harris, of the Survey, a southern-Appalachian geologist whose interests had moved northward from the Ozarks, came into the Oil & Gas Branch, too. One day, he mentioned to Anita that he understood she was interested in conodonts. He flexplek huren haarlem said he would like to have some of her rock samples analyzed for “organic maturation.” She listened to this dark-haired blue-eyed geologist as if he had come from a place a great deal more distant than the Ozarks. Just how did he propose to discern organic maturation? “Do you do that chemically?” she asked him. “Yes,” he said. “You can. And you can also do it by observing changes in organic materials such as fossil pollen and spores, where they exist.” “How do you do that?” she said. “By looking at color change,” he said. “You see, the pollen and spores-” “Stop!” she said. “Stop right there. They change from pale yellow to brown to black. Am I right?” “Right,” he said. He was matter-of-fact in tone. He was, among
other things, an oil geologist, while she was not. Oil companies had been using the colors of fossil pollen and fossil spores to help identify rock formations that had achieved the sorts of temperatures in which oil might form. Land-based plants, with their pollen and spores, had not developed on earth until a hundred and thirty million years after the beginning of the Paleozoic era, however. Nor would they ever be as plentiful and as nearly ubiquitous as marine fossils. Hearing Leonard Harris mention oil companies and their use of color alteration in pollen and spores, Anita realized in the instant that she had-in her words-“reinvented the wheel.” And then some. She had not known that pollen and spores were used as geothermometers in the flexplek huren breda oil business, and now that she knew it she could see at once that conodonts used for the same purpose would have different geographical applications, covering greater ranges of temperature and different segments of time. “I think I can do the assessments easier and better by using conodonts,” she said to Harris. “Conodonts change color, too, and in the same way.” It was his tum to be surprised. “How come I never heard about that?” he said. She said, “Because no one knows it.”
