... source regions and crustal involvement, and have been previously proposed for Rio Grande rift lavas. The flows of the Cat Hills, Cat Mesa, Wind Mesa, Mesita Negra, and Cerro Verde were erupted during or after deposition of the Santa Fe Group sediments. The Santa Fe Group sediments are Neogene...

... More than 95% of the eastern Snake River Plain (ESRP) is covered by basaltic lava flows erupted in the Brunhes Normal-Polarity Chron; thus they are younger than 730 ka. About 13% of the area of the ESRP is covered by lava fields of latest Pleistocene and Holocene age <15 ka. More than 90...

... We used tephrochronology for upper Neogene deposits in the Española Basin and the adjoining Jemez Mountains volcanic field in the Rio Grande rift, northern New Mexico, to correlate key tephra strata in the study area, identify the sources for many of these tephra, and refine the maximum age...

... flows on the western side of the volcanic field. Cerros del Rio lavas were erupted from vents located both east and west of the Rio Grande ( Smith et al., 1970 ; Aubele, 1978 ; Kelley, 1978 ; Sawyer et al., 2002 ). On the Pajarito Plateau, the top of these basalts ( Fig. 13 ) formed a broad north...

...J. A. Wolff; C. E. Heikoop; R. Ellisor Abstract Weakly alkaline lavas erupted in the Pliocene Cerros del Rio and El Alto volcanic fields in the Española basin of the Rio Grande rift have the unusual trace element signature of approximately chondritic K/Nb combined with high La/Nb and Th/Nb...
