December Presentation

Journey to the Lower Appalachian Lower Middle Crust - Field Trip Lecture

 

By

Dr. Robert D. Hatcher, Jr.
Distinguished Scientist and Professor Emeritus
Earth and Planetary Sciences
UT-Knoxville


Abstract

This meeting will focus on the background and preparatory description of the Field Trip, with details regarding the point of departure, schedule, and lining up of drivers to be worked out. As indicated in the 9/13/24 email for the Fall Field Trip, we are limited to four vehicles with 4 persons each, and unless there are cancellations in the next few weeks the Field Trip is full. ETGS will maintain a waiting list, so if you are interested please send along an email and if there are any cancellations we will get back to you as soon as possible. However, all members are welcome to participate in the December 2nd Presentation.

Field Trip description: Tentatively, we will leave at 8:30 a.m. from Oak Ridge and drive south on I-75 to the Calhoun exit (TN 163) and take 163E to US 411 to US 64 and turn east on 64 then stop at Ocoee #1 Dam. Our traverse to the lower middle crust begins with sandstone of the Chilhowee Group that disappears immediately to the West of the dam parking area, because its base is cut off by the 400 km displacement Great Smoky fault (not exposed here). We will move eastward across the western and central Blue Ridge of TN and NC and end immediately west of Franklin, NC. Our progress from the upper crust into the middle then the lower middle crust will be marked by the changes in minerals present in similar rock types (sandstone and shale) until melt starts to appear to the east.

 

Biography
 

Education: Vanderbilt University, Nashville, Tennessee B. A. 1961 (majors: geology, chemistry; minor math), M. S. 1962 (geology), University of Tennessee, Knoxville, Tennessee Ph. D. 1965 (structural geology; two foreign languages required)

Professional Employment: Geologist, Humble Oil and Refining Company (1965-66), Clemson University (1966-78, Assistant Professor to Full Professor), Florida State University (1978-80, Full Professor), University of South Carolina (1980-86, Full Professor), and University of Tennessee-Knoxville and Oak Ridge National Laboratory Distinguished Scientist (1986-2000), UT Distinguished Scientist and Professor (2000-2018). University of Tennessee Distinguished Scientist and Professor Emeritus 2018- Present.

Research Interests: Primary research goal is to gain a better understanding of the evolution of continental crust, mostly through the study of mountain chains and mature crust. Most of my research has been concentrated in the southern and central Appalachians, but large amounts of time have been spent visiting and studying other mountain chains, and Precambrian continental crust. My primary interest is in the mechanics and kinematics of large faults, which form a natural transition into a related long-term interest in the geologic controls of petroleum occurrence in the Appalachians, radioactive waste management, the causes of intraplate seismicity and geologic evidence for determination of recurrence intervals for intraplate earthquakes. While I am a structural geologist, most of my research is interdisciplinary, integrating stratigraphic, geochronologic, geochemical, and geophysical data into structural studies. I am primarily a field geologist, however, and field data form the basis for all other supporting studies. I have been involved for many years with geophysicists and geologists in other academic institutions and the USGS in the geologic interpretation of seismic reflection and potential field (aeromagnetic and gravity) data.

Research Support: Received over $5M in grants and contracts from the National Science Foundation, Nuclear Regulatory Commission, U.S. Department of Energy, U.S. Department of the Interior, state geological surveys, and private industry.

Professional Service (Abbreviated): Editor (with W. A. Thomas) Geological Society of America Bulletin (1982-88); President, Geological Society of America (1993); President, American Geological Institute (1996); Trustee, GSA Foundation (1999-2007), Chair of the GSA Foundation Board (2005-07); National Academy of Sciences/National Research Council Board on Radioactive Waste Management (1990-96); Federal Advisory Committee on Nuclear Reactor Safety Research (Nuclear Regulatory Commission, 1993-96); Federal Advisory Committee for the National Cooperative Geologic Mapping Program (Department of the Interior, 1996-2006); Federal Advisory Committee Oak Ridge Site Specific Advisory Board (2009-2015; have also served on numerous committees of GSA, AAPG, AGU, and other organizations. Fellow: AAAS, Geological Society of America, Geological Association of Canada.

Medals and Awards: Geological Society of America Distinguished Service Award (1988, the first ever awarded), AAPG I. C. White Award (1997), honorary citizen of West Virginia (by the Governor, 1998), John T. Galey Award by the Eastern Section of the American Association of Petroleum Geologists (2001), American Geological Institute Ian Campbell Medal (2006), Geological Society of America Penrose Medal (2006), and American Geological Institute Marcus Milling Legendary Geoscientist Medal (2014). The latter three medals constitute the highest levels of career recognition/achievement possible in my profession.

Publications: Author or co-author of >200 scientific publications, including 10 books.

Graduate Students: 53 M. S. theses and 18 Ph. D. dissertations completed since began working in graduate departments in 1978.

 

 

 

Greetings, and welcome to the December 2, 2024 ETGS hybrid meeting.
 

If you attend via Zoom as a courtesy please mute your cell phone or the microphone in your laptop/tablet to minimize background noise and feedback echos. We will also make an effort to mute all participants - at least until the presentation is finished. Please use the chat feature to type any comments or questions you may have. We recommend that you send questions for the speaker to "everyone" so all participants can see the question. In the interest of time, we may hold the Q&A at the end of the presentation.

We will create an in-person and virtual attendance list. It is not always possible to tell who is participating on-line, especially for those joining by phone, so please email etgs@live.com to be listed on the attendance sheet. Let us know exactly how your name should appear on the list. We will add a note explaining the lack of signatures due to remote participation and have an ETGS officer sign as usual.

Thank you for your patience and understanding as we try this online format. As always, we welcome and appreciate your feedback and suggestions for improvement.
