Anacacho Limestone stratigraphic column in Texas

Description

The Anacacho Limestone is composed predominantly of limestone (wackestone, packstone, and grainstone).[1]

Geographic Extent

Outcrops of the Anacacho Limestone are present in Kinney, Uvalde, Medina, and Bexar Counties of Texas.[2]

Stratigraphic Setting

The Anacacho Limestone overlies the Upson Clay, and is overlain by the Corsicana Marl.[3]

Age

The Anacacho Limestone is of Cretaceous (Campanian) age.[4]

Interpretation of Depositional Environment

Most of the Anacacho Limestone is interpreted as having accumulated in relatively shallow (<50 m depth) marine water.[5]
