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]
