The Geology of the Carolina terrane in Chatham County, NC – Results of New Geologic Mapping by the NC Geological Survey.
2023 marks the 200th Anniversary of the North Carolina Geological Survey (NCGS). As part of the Survey’s anniversary celebration activities, the NCGS is hosting the 2023 Carolina Geological Society field trip. The geology of Chatham County is the theme of the trip with the main focus being the results of new mapping in the Carolina terrane portion of the county.
In late 2022, a new compiled geologic map of Chatham County was released: Link to Map. The field trip will visit multiple outcrops throughout the County
Some of the stops will include:
Saturday Field Trip
Metamorphosed dacitic tuffs and andesitic to basaltic rocks of the Hyco Formation at the eastern edge of the Carolina terrane on the west shore of Jordan Lake.
Metamorphosed andesitic and dacitic lavas of the Hyco Formation in the Haw River at the HWY 64 bridge.
Examples of metamorphosed intermediate to mafic composition volcanosedimentary rocks of the Hyco Formation.
Outcrop of conglomerates of the Aaron Formation
Outcrops of sandstones that were previously interpreted as part of the Aaron Formation before new detrital zircon data.
Sunday Field Trip
A visit to an abandoned quarry on the Deep River that exposes brecciated rocks of the Hyco Formation.
A visit to an outcrop of Triassic conglomerate near the trace of the Bonsal-Morrisville fault.
