Thick packages of Cambrian subalkaline, tholeiitic basalt and andesite lavas erupted in Oklahoma (U.S.A.).
Bulk major, trace, and Sr-Nd isotope data consistent with flood basalt volcanism during a rifting event.
Gabbros in the Wichita Mountains (U.S.A.) and dikes in the Arbuckle Mountains region are part of the same magmatic event.
Data confirms the presence of an additional flood basalt province in North America.
