| Comment | Whole rock basalt. Lava flows cap a broad mesa at the north end of the Aguila Mountains that dips about 10 deg to the north. The mesa is cut by several vertical faults that strike N35 deg W and the surface is stepped in a piano key fashion. Beneath the lava is a massive bedded, weakly indurated volcani-clastic unit. Arroyos cut in the surface of this unit are preserved at the contact. |
