Abstract

The Gulf of Mexico formed during a period of seafloor spreading and continental rifting during which there was a period of magmatism in central Texas, now known as the Balcones igneous province. Knippa basalt is a volcanic rock taken from Knippa, Texas by NASA at the turn of the space age as a comparison with the newest lunar basalt samples. This basalt is a representation of the magma which erupted onto the surface around 70 million years ago and will provide details on the origin and composition of the magma and also be used as a comparison to other previously studied samples from other areas of the province.
