Title: Rocks Underlying Cretaceous in Balcones Fault Zone of Central Texas

Author(s): E. H. Sellards (2)


Underlying the Cretaceous in the Balcones fault zone of central Texas are sediments consisting chiefly of shales and sandstones which are somewhat altered and are only sparingly fossiliferous. On the basis of fossils obtained from one of the wells, together with the general appearance of the shales and sandstones, the sediments are believed to be largely of Paleozoic age. They are regarded as having accumulated in a trough or syncline in front of the land mass Llanoria, this trough being continuous toward the northeast with the Ouachita Mountains of Oklahoma and westward with the Marathon uplift of Trans-Pecos Texas.
