Geology
Tesnus, Texas, is the namesake for the geological formation known either as the Tesnus Formation or Tesnus Shale. Bedrock outcrops around Tesnus, Texas serve as the type locality for the Tesnus Formation.[4]
The Upper Mississippian – Lower Pennsylvanian Tesnus Formation is a significant, wide-spread formation that is composed primarily of interbedded olive-drab to black shale, siltstone, and fine- to very fine-grained sandstone. It thins from 2,000 meters (6,600 ft) in the eastern Marathon Uplift westward to 100 meters (330 ft). The base of the Tesnus Formation in the eastern Marathon Uplift consists of a 100 meters (330 ft) thick shale blanket that makes up the entire thickness of this formation in the west. The sandstone layers are as much as 5 meters (16 ft)thick, but most layers are between 30 and 150 cm (12 and 59 in). Locally, its shales contain carbonaceous plant fragments and spores and some of its sandstone beds contain wood casts up to 30 cm (12 in) long. Rare fossils of conodonts, radiolaria, sponge spicules, a crustacean, and inarticulate brachiopods have also been found in the Tesnus Formation.[5]
