The Weches Formation is a greensand, clay, and shale geologic formation in Louisiana and Eastern Texas.[1][2] It preserves fossils dating back to the Paleogene period, specifically the Eocene.
Description
The Weches Formation is a fossiliferous glauconite rich sand that graduates into a clay.[2] It is considered one of the principal iron bearing beds in Eastern Texas, and is mined for sand in gravel in parts of Texas where exposed.[2][3] The Weches Formation was originally called the Weches Greensand, and was considered a member of the Mount Selman Formation before being raised to formation status.[2][4]
