Geosciences, Geoarchaeology expert to present two lectures at TU, Feb. 12-13
Thursday, February 07, 2008
The University of Tulsa will host two lectures next week by plate tectonics specialist William Dickinson, professor emeritus of geosciences at the University of Arizona.
"Dr. Dickinson is one of the more renowned geologists of the last several decades," said Winton Cornell of the TU Department of Geosciences. "He has made many wide-ranging contributions to our understanding of how earth’s outer, rocky layers move and have caused change in the western mountain system of North America."
Dickinson’s first lecture on Feb. 12 will address geoarchaeology, an interdisciplinary study that uses techniques and expertise from geography and other earth sciences to give archaeologists more tools in understanding the past. His presentation, "Geoarchaeology of Tonga and its Pacific Connections," will take place at 12:30 p.m. Feb. 12 in Room M1 in Keplinger Hall. The Kingdom of Tonga consists of 170 small islands in the southwest Pacific Ocean, neighboring Fiji and the Cook Islands.
On Feb. 13, Dickinson will present “Anatomy and Evolution of the North American Cordillera” at noon in Room M8 in Keplinger Hall. The North American Cordillera refers to a series of mountain ranges that run from Mexico into Alaska that form a type of geological backbone in North America, including the Rocky Mountains. The Cordilleran system is but one segment of the circum-Pacific volcanic and earthquake belt.
Dickinson has been recognized with several of the top awards in geology, including the Penrose Medal in 1991 by the Geological Society of America and the William H. Twenhofel Medal in 2000 by the Society for Sedimentary Geology. The Arizona Geological Society held a symposium in his honor this past fall.
The Feb. 12–13 lectures are free and open to the public. For more information, contact the Department of Geosciences at (918) 631-2517.
