Geology and Energy Resources of the Triassic Basins of Northern Virginia

The TSOP field trip (September 24, all day) will visit the Triassic coal mining district near Richmond, Virginia. Triassic-age coal was discovered and first mined for domestic needs in this area by Huguenot settlers during Colonial times (1703), and the resource became an important source of energy in the region during the 1800’s. The mines were commonly gassy and the strata were faulted, so that mining conditions were difficult as well as primitive.

The field trip will visit exposures that illustrate the stratigraphy of the Richmond Triassic Basin, as well as the available remnants of old mine workings. There may be a traverse of moderate length and difficulty. A discussion of the geology and energy resources of the Triassic Basins of Northern Virginia will be presented.


Cost, including van, lunch, and publications - $50.00. Limit – 25 people.

Photographs of the fault zone along the western edge of the
Richmond Triassic Basin, in Luck Stone's Boscobel quarry near Manakin,
Virginia. The quarry has been operating for about 150 years. Photos 1
and 2 show sheared granite and shale mylonite. Photos 3 and 4 show
faulted Triassic strata adjacent to the border fault.
