Summary:
Pg. 424 (fig. 3), 445-451. Cieneguilla limburgite. Proposed for series of flows and ejectamenta, with associated waterlaid beds, exposed in vicinity of La Cienega. Thickness at type locality 590 feet. At Cieneguilla, overlain with angular unconformity by Pleistocene alluvium of Santa Fe Plateau, Pleistocene basalt of the Mesa Negra, and by younger alluvium in Santa Fe Creek. Base of section not exposed; maximum stratigraphic interval during which a small body of augite quartz latite was intruded, solidified, and exposed by subsequent erosion. Appears to be Oligocene or earliest Miocene.
Type locality: Canyon of Santa Fe Creek between settlements of Canyon and Cieneguilla, Cerillos Hills, Galisteo-Tongue area. [Named from settlement of Cieneguilla, Santa Fe Co., NM.]
