A Road Guide to the Harpeth River and Stones River Fault Zones
Date: Sunday, September 24, 2017 Time: 7:30 am to 6:00 pm
Trip includes box lunch, snacks, water, transportation. Leader: Mark Abolins, Department of Geosciences, Middle Tennessee State University
The Nashville dome is the southern extension of the Cincinnati Arch and contains widespread joints and folds with minor fault exposure. Four blind nor- mal faults have been iden- tified on the northwest approximately 20 miles
south of Nashville. The Harpeth River fault zone includes the Peytonsville, Arno, McClory Creek, and McDaniel fault zones. This area includes the Harpeth River syncline and construc- tion of Tennessee State Route 840 revealed minor normal faults, non-vertical joints, and mesoscale folds. No faults are depicted on existing geologic maps, but these maps reveal mac- roscale folding of the contact between the Ordovician Carters Formation and the overlying Hermitage Formation. The Stones River fault zone includes the Ordovician Lebanon limestone and is surrounded by older strata of the Ordovician Ridley and
Mesoscale faults are exposed at the Harpeth River syncline, but not at the Stones River syncline stops. Participants will examine minor normal faults, mesoscale folds, and joints. At these stops, participants can discuss the hypothesis that the
minor fractures and mesoscale folds formed through movement on larger blind normal faults. (Stop 1), Arno (Stop 2), McClory Creek (Stop 3), and McDaniel (Stop 4), and the entire zone (Harpeth River fault zone) is a little less than 4 miles wide mesoscale structures interpreted as fault-related. At Stop 6, joints are exposed in a north-plunging fold hinge.
natural trenches, and a cedar forest grows atop the area. The the morning of 31 December 1862 during the American Civil War Battle of Stones River. Union soldiers held out in this defensive position throughout much of the morning, although Confederate soldiers took the position by noon. Casualties were high on both sides and some Union units lost one third of their men, providing a spectacular example of the connection between karst and Civil War casualties.
Mammoth Cave, Crumps Cave, and Corvette Museum
Date: Sunday, September 24, 2017 Time: 7:30 am to 6:00 pm
Trip includes lunch at the cave, snacks, water, transportation & Museum entrance. Leader: Chris Groves, Western Kentucky University, Bowling Green, KY, Pat Kambesis, Western Kentucky University, Bowling Green, KY, Donald K. Lumm, Ph.D., CPG-08987.
Mammoth Cave is the longest cave system in the world, with over 405 miles mapped as of 2015. Located only 1 ½ hours from Nashville in western Kentucky, the cave system has five levels developed in soluble Upper Mississippian limestone forma- tions, and extends to a depth of approximately 400 feet below the karst landscape, which is capped by resistant, non soluble Upper Mississippian sandstone. The field trip will present and discuss the primary elements for developing the classic karst topography and cave system, including the lithology, structure, and climate.
Field trip stops include an overview of the karst topography from a promontory located near Park City, Kentucky. We will visit Crumps Cave Research and & Educational Preserve, an active research and monitoring facility located near Smiths Grove, Kentucky and managed by the Hoffman Environmental Research Institute of Western Kentucky University.
