150 Is it Possible to Build a Perfect Continent?
Computers, Science, Tech | Registration opens 12/3/24 9:00 AM EST
Continental crust is the long-time scorekeeper of Earth history, while ocean crust is ephemeral. We want to explore the makeup of continents and ask if a perfect one already exists. After an introduction to basic principles (session 1), we will explore the origin of continental and oceanic crust, explore the composition (rocks, structure, and evolution) of existing continents (session 2); continental growth (session 3); and roles of continental and oceanic crust through time (sessions 4 and 5); then build our own future ideal continent (session 5); and have a field-trip introduction (session 6). Field trip to northeast Tennessee and western North Carolina to see the only locally accessible old crust, recycled into newer Appalachian crust (Saturday, March 1). Field trip follow-up. Why do other planets not have continents (and oceans)? Does an already near-perfect continent exist?
Robert D. (Bob) Hatcher
Bob Hatcher officially “retired” on June 30, 2018, after 32 years at University of Tennessee following six years at South Carolina, two years at Florida State, 12 years at Clemson, and a year with Humble Oil and Refining Company (now ExxonMobil): a career spanning 51 years that began after receiving a BA in geology and chemistry (Vanderbilt), MS in geology (Vanderbilt), PhD in geology (UT). During his career Bob published more than 200 refereed scientific works, including 10 books, along with many field guides and reports. The 3rd edition of his structural geology text was published in 2020. He also taught undergrad structural geology, physical and historical geology, mineralogy, optical mineralogy, petrology, and environmental geology as well as graduate level tectonics, structural geology, and Appalachian tectonics, to more than 2,000 students in four universities.
