The map area lies within the Abiquiu embayment, an early (pre-Miocene) extensional basin of the Rio Grande rift. Rocks exposed include continental Paleozoic and Mesozoic rocks of the Colorado Plateau and Cenozoic basin-fill deposits and volcanic rocks of the Rio Grande rift. Paleozoic units include the Late Pennsylvanian to Early Permian Cutler Group, undivided (Pcu). Mesozoic units are Upper Triassic Chinle Group, undivided (Trcu) and middle Jurassic Entrada Sandstone (Je) and Todilto Limestone Member (Jt) of the Wanakah Formation. Mesozoic rocks are folded in some areas and overlain disconformably by Cenozoic rocks. Cenozoic sedimentary rocks are composed of the Eocene El Rito Formation (Te), Oligocene Ritito Conglomerate (Trc), Oligocene-Miocene Abiquiu Formation (Ta), and Miocene Chama-El Rito (Ttc) and Ojo Caliente Sandstone (Tto) Members of the Tesuque Formation of the Santa Fe Group. Volcanic rocks include the Lobato Basalt (Tlb) (~15-9 Ma, Aldrich and Dethier, 1990; ~10-8 Ma, Bachman and Mehnert, 1978; Manley and Mehnert, 1981; and ~10-8 Ma, sample A99, A50, and A48, Maldonado and Miggins, 2007), the El Alto Basalt (Teb) (~3 Ma, Manley and Mehnert, 1981; Baldridge and others, 1980; sample A13, Maldonado and Miggins, 2007), and daciteof the Tschicoma Formation (Ttd) (~2 Ma, Gardener and Goff, 1984). Quaternary deposits consist ofinset ancestral axial and tributary Rio Chama deposits and Holocene floodplain alluvium, fan and pediment alluvium, and landslide colluvium. Axial or side stream terrace benches are found approximately 25-150 m above the present day Rio Chama channel. One set of terraces (Qt2) at about 120 m height is as old as 640 ka, based on the presence of the Lava Creek B ash in map area and east of the map area as indicated by Dethier and others (1990) and Gonzalez and Dethier (1991), although the ash was not found in map area. Delineation of terrace alluvium is modified from Gonzalez (1993) and Gonzalez and Dethier (1993). Tributary gravels beneath the Lobato Basalt (Tlb) and El Alto Basalt (Teb) contain clasts of a fluvial systemthat probably represent several ancestral Tertiary Rio Chama courses. Tops of these gravels are about 580 m and 395 m, respectively, above the modern Rio Chama. Clasts consist mostly of subrounded towell-rounded Paleozoic quartzite and granite, Tertiary volcanics, and traces of Pedernal Chert Member of the Abiquiu Formation (Moore, 2000) (referred to as Pedernal Chert in this report). Gravels containing quartzite and Pedernal Chert also are present under the lavas capping Sierra Negra (sample A49, 5.56 Ma (plateau age), 5.44 Ma (isochron age) Maldonado and Miggins, 2007; ~5 Ma, Baldridge and others, 1980) and the Servilleta Basalt flows at Black Mesa (~4-3 Ma; Manley, 1976; Laughlin and others, 1993, unpub. report for Los Alamos National Laboratory, sample A51, 3.69 Ma (plateau age), 3.45 Ma (isochron age) Maldonado and Miggins, 2007) northeast and east of the map area, respectively. A major fault in the map area is the Cañones fault zone located in the northwest corner of map area that separates the Abiquiu embayment from the Colorado Plateau. The Abiquiu embayment is a shallow basin that forms the western margin of the Rio Grande rift (Baldridge and others, 1994), east of the deeper Española basin. The Cañones fault developed during deposition of the Abiquiu Formation (Ta), Oligocene Ritito Conglomerate (Trc), and the El Rito Formation (Te) based on the presence of these units on the Cerro de Pedernal of the Colorado Plateau (Smith, 1995; Moore, 2000; Kelley and others, 2005) and the Abiquiu embayment. The fault appears to have continued to be active for some time based on the following: 1) a dike referred to informally as the basaltic dike of Red Wash Canyon (Tbr) located in the northwest corner of map area intrudes the lower part of the Chinle Group of the Colorado Plateau Province and the Trc unit of the Abiquiu embayment (just west of map boundary). The dike, dated at 19.63 +/- 0.40 Ma (sample A65, Maldonado and Miggins, 2007) is offset approximately 2 km right-laterally by the Cañones fault. The dike has the same age as the Cerrito de la Ventana dikes (Tcd, sample A23, 19.58 +/- 0.09 Ma (weight mean age), 19.22 +/- 0.30 Ma (isochron age) Maldonado and Miggins, 2007) that intrude units Trc and Ta in the Abiquiu embayment; 2) the Lobato Basalt (10-8 Ma), with source in the embayment is found both on the Colorado Plateau and the embayment, and 3) latest offset is constrained by the presence of two different basalts (Lobato Basalt, Tlb and El Alto Basalt, Teb) on the Colorado Plateau with centers in the embayment. The Lobato Basalt is displaced across the Cañones fault whereas the El Alto Basalt (~3 Ma) is not (Maldonado, 2004). Other major faults related to rift formation located east from the Cañones fault are; Garcia, Cerrito Blanco, Barranca, Plaza Colorado, and Madera Canyon. These series of faults may be growth faults that form a zone of step faults that down-drop strata to the east, towards the Española basin, a deeper part of the Rio Grande rift. Landslides are very common in map area that have separated from their source outcrop. On Mesa de Abiquiu, south of Abiquiu and above Abiquiu Creek, a major incipient fissure zone has formed near the edge of the El Alto Basalt (Teb). The zone strikes northeast and is about 3.5 km long with gaps as much as 1 m. This fissure zone may eventually form landslides affecting the Abiquiu Creek area. Another important structure in the map area are blocks bounded by a low-angle fault referred to here as the Abiquiu fault. The Abiquiu fault separates an upper plate from a lower plate. The upper plate is composed of the transitional zone (Ttoc) of the Ojo Caliente Sandstone (Tto) and Chama-El Rito (Ttc) Members of Tesuque Formation. In most areas, the lower plate consists of the Abiquiu Formation (Ta), but in the northern part of the Cerrito Blanco area, the lower plate consists of the Ritito Conglomerate (Trc). The upper plate may have originally formed a continuous sheet that formed as a mega-slide block that subsequently has been broken and eroded into smaller blocks. The blocks range from about 0.1 km to 3.5 km with the Rio Chama flowing thru the largest block. In the Cerrito Blanco area, referred to as “Battleship Rock” by Smith (1938), the upper and lower plates and Abiquiu fault have been offset by movement on the Cerrito Blanco fault resulting in cementation of the upper plate. The upper plate was probably first fractured and shattered forming a "shattered breccia" by movement on the Abiquiu fault followed by solutions migrating up along the Cerrito Blanco fault zone cementing the upper plate. In the southwestern part of the map area, south of the Rio Chama, smaller blocks are present that may have been part of this large sheet. There, the upper plate is composed of the transitional zone (Ttoc) and basaltic dikes of Barranca (Tbb). In summary, the evidence for this sheet and the low-angle structure are the following: 1) upper plate above the low-angle fault (Abiquiu fault) is brecciated, intensely fractured, and contains numerous faults with small displacements; 2) in some areas (northern part of Cerrito de Blanco) steep dips in the upper plate dip into the lower plate and form an angular discordance; 3) stratigraphically, the upper plate is out of place with some section missing; in the southern part of the Cerrito Blanco area, the upper plate overlies the Abiquiu Formation (Ta) and to the north, it overlies the Ritito Conglomerate (Trc); 4) in the northern part of the Cerrito Blanco area, the Chama-El Rito (Ttc) appears to overlie the Ojo Caliente (Tto) which could imply overturning of the upper plate or perhaps just intertonguing of these two units; 5) south of the Rio Chama, in the western part of map area, south of the village of Barranca, dikes referred to as dikes of Barranca (Tbb) intrude the upper plate (Ttoc) and are truncated by the Abiquiu fault, suggesting that intrusion of the dikes are pre-detachment of the upper plate. Older structures, of Laramide age, are preserved as folds in the Mesozoic rocks in the northwestern part of the map area, and locally as small reverse faults in the undivided Chinle Group in the Arroyo del Cobre area.
