ABSTRACT

Opening of the Gulf of Mexico in the Early Jurassic probably initiated movement on the Mexia and Talco fault zones of East Texas. The fault patterns associated with these zones are generally compatible with a model whereby the Gulf opened along a northwest-trending spreading center. This implies divergent strike-slip movement on the Mexia fault zone and simple rifting on the Talco fault zone. Late Jurassic-Eocene movement on the zones is most likely due to mobilization and movement of the Jurassic-age Louann Salt.
