Direction of compression was essentially the same as that during Eocene Laramide deformation. The observations support a continental-arc tectonic setting. The beginning of extension between 32 and 30 m.y. ago coincides with a regional change in style of magmatism from intrusions and eruptions spanning a wide range in chemical composition to basaltic volcanism in Texas and to bimodal but dominantly rhyolitic volcanism in northern Mexico.
