Servilleta basalts increase in thickness from south to north within the Taos Valley; they are absent in BOR1, present as a single thin ﬂow in BOR3, and present as three multiple-ﬂow sequences at BOR4, K3, RP2500, and the Airport well. The Ojo Caliente Sandstone Member varies in apparent thickness from thin or absent at BOR1 and BOR2/3 to greater than 1000 ft (300 m) at RP2500 to 340 ft (100 m) at the Airport well. The apparent thickness of the Ojo Caliente is greatest along the Rio Pueblo, suggesting deposition in a depression, possibly an ancestral Rio Hondo or Rio Pueblo drainage, during mid-to-late-Miocene time. The Ojo Caliente sand may have been derived from the west, accumulating against Chama-El Rito alluvial fans building off the eastern mountain front. Data from the drilling program are also used to identify and constrain offset on several intrabasin faults and a mountain front graben bounded on the west by the Seco Fault, across which the Servilleta Formation is offset 950 ft (290 m), and on the east by the Town Yard fault. The average subsidence rate within the graben is estimated as approximately 0.1mm/yr (0.3 ft/1000yr). Down-to-the west offset across the Town Yard Fault is > 1390 ft (420 m).","PeriodicalId":224165,"journal":{"name":"Geology of the Taos Region","volume":"2022 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114913136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Embudo fault, which is a transfer zone that strikes N60˚E across the north-trending Rio Grande rift, accommodates differential movement between the east-tilted San Luis Basin on the north and the west-tilted Española Basin on the south. Detailed geologic mapping along the northeastern 18 km of the Embudo fault provides evidence of late Pleistocene and possibly Holocene displacement along many discontinu- ous fault strands that are distributed over a width of several kilometers. The northeastern part of the Embudo fault has had left-oblique slip during the late Quaternary, as suggested by substantial along-strike variations in scarp heights, subhorizontal slickensides on fault planes, and reverse faulting within a right step-over. Fault-scarp heights along the northeastern part of the Embudo fault appear to correlate more with local strikes of fault strands than with age. The fault strands with northeasterly strikes exhibit prominent scarps, and strands with more westerly strikes have low scarps and subtle geomorphic expression. In comparison, the north-striking, rift-margin Sangre de Cristo fault, directly north of the Embudo fault, has prominent,","PeriodicalId":224165,"journal":{"name":"Geology of the Taos Region","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123235571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The estimates are based on the vertical offset of ca. 3 Ma Servilleta Basalt ﬂows across the EFZ south- west of the Village of Pilar, and an average slip vector for that segment of the fault zone. A previous estimate of 130 m/m.y. average, east-west Quaternary (last 1.8 Ma) extension rate across the southern San Luis Basin was based on the slip rates on the Sangre de Cristo and Los Cordovas faults. If these independent estimates of average east-west extension are approximately correct, then the rate of extension across the southern basin may have increased slightly since the late Pliocene. Several other published estimates of slip on the Sangre de Cristo fault can be used to approximate average extension rates as far back as about 28 Ma. Although some of these estimates are poorly constrained, they can be used to speculate that: 1) average San Luis Basin extension rates may have increased since rift inception; and 2) average extension rates may have been greater across the southern San Luis Basin than across the central part of the basin near the Colorado border. The ﬁrst speculation is difﬁcult to evaluate, as extension rates have certainly varied through time. The second speculation is consistent with published conclusions that the cumulative amount of extension increases northward among rift basins, and that rifting has progressed northward through Neogene time.","PeriodicalId":224165,"journal":{"name":"Geology of the Taos Region","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127709966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detailed topographic surveys at the site show that the primary fault scarp, which is formed on late Pleistocene alluvial deposits, has about 3 m of net vertical tec- tonic displacement. A bevel in the scarp suggests that two surface ruptures occurred since deposition of the alluvial fan, each with about 1.5 m of vertical displacement. These displacements imply the occurrence of earthquakes having magnitudes in the range of M 6.8 to M 7.0. Stratigraphic relations exposed in a 30-m-long trench across the primary fault scarp show the presence of middle Pleistocene eolian and alluvial deposits faulted against late Pleistocene alluvial and colluvial deposits on the eastern, downthrown side of the fault. Stratigraphic evidence of surface-fault rupture includes scarp-derived colluvium and ﬁssure-ﬁll deposits that probably were deposited immediately following the surface rupture. The main fault strand consists of a primary west-dipping fault plane and secondary faulting in a 6-m-wide zone in the hanging wall. The fault zone contains multiple anastomosing strands in pervasively sheared alluvium, and probably has lower permeability than surﬁcial deposits east of the fault, but higher permeability compared to deposits west of the fault. Calcium-carbonate cementation along fault planes in ﬁne- and medium-grained deposits may be indicative of preferential groundwater ﬂow downdip along the fault. Thus, major strands of the southern Sangre de Cristo fault probably provide preferential pathways for the downward ﬂow of vadose-zone groundwater in unconsolidated near-surface deposits.","PeriodicalId":224165,"journal":{"name":"Geology of the Taos Region","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114168620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Testing results from a series of municipal, exploratory, subdivision, and domestic wells are also used to characterize hydrologic properties (T, K, K', and S), and the effect of faults on groundwater flow in shallow and deep basin fill aquifers. The shallow unconfined to leaky-confined alluvial aquifer includes alluvial deposits and the underlying Servilleta Formation (Agua Azul aquifer facies). The deep leaky-confined to confined aquifer includes Tertiary age rift-fill sediments below the Servilleta Formation and is subdivided into the Chama-El Rito and Ojo Caliente aquifer facies. Although faults typically do not act as impermeable boundaries in the shallow alluvial aquifer and groundwater flow in the shallow aquifer is not significantly affected by faults, the Seco fault and several of the Los Cordovas faults act as impermeable boundaries in the deep basin fill aquifer. However, other Los Cordovas faults apparently do not affect groundwater flow in the deep aquifer, suggesting variable cementation along fault planes at depth. The Town Yard fault appears to be a zone of enhanced permeability in the shallow alluvial aquifer, and does not act as an impermeable boundary in the deep basin fill aquifer. Intrabasin faults such as the Seco fault that exhibit significant offset likely cause some compartmentalization of the deep aquifer system.","PeriodicalId":224165,"journal":{"name":"Geology of the Taos Region","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116760081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
