Alkaline volcanism related to flat subduction of the Farallon plate was widespread in the Trans-Pecos Volcanic Province. The transition from K-rich trachyte and rhyolite to mafic alkaline basalt and hawaiitie appears to mark the change from subduction-related magmatism to continental rift-related magmatism. Big Bend Ranch State Park is an ideal location to study these types of rocks.
