Professor Emeritus of Geology

PhD (1962) University of Kansas

Teaching Interests:

  • Sorauf is presently retired from teaching, but is available to lecture. In the past several years he has given lectures on Modern and Fossil corals at the University of South Florida (Tampa) and the U.S. Geological Survey in St. Petersburg, FL. Jim has also lectured on topics such as the Grand Canyon and the Devonian System at U.S.F. (Tampa).

Research Interests:

  • Paleontology: morphology and systematics of Rugosa and Scleractinia; diagenesis of coral skeletal carbonate; biomineralization of modern and fossil corals.

Current Research

  • Active research is focusing on the microstructure and microarchitecture of modern reef corals, with present emphasis on annual density banding, its causes and its implications. This is almost entirely a study by Scanning Electron Microscope of the fine details of reef coral skeleton. Research also continues on Permian corals from the island of Timor, Indonesia, with a publication forthcoming in the Australasian journal Alcheringa. Research on modern reef corals is conducted in the Florida Keys and at the United States Geological Survey in St. Petersburg, Florida, during winter months and involves research personnel and technical facilities of the U.S.G.S. At present, two manuscripts are in press that deal with this work.
