| Comment | Whole rock, basalt. Lava flow caps westernmost of the Mesas de Malpais. The basalt preserves a fossil desert surface on unconsolidated alluvium which fills a steep topography cut on Precambrian gneiss. Stream channels are superposed on both the basalt and the gneiss. This extensive lava flow has been offset by normal faults. |
