Knowledge of how fluids move from the surface through perched zones to the aquifer is still developing. This study looks at the prior landscape “sealed” between two major ash flows (Otowi and Tshirege Members of the Bandelier Tuff at 1.6 and 1.2 Ma), within Bandelier National Monument (BNM). The ~380,000 year interval between the Bandelier eruptions, informally termed the Cerro Toledo interval, contains up to 120 m thick deposits that provide favorable settings for perched zones. Windows into this landscape are exposed in Frijoles and Alamo Canyons, two narrow, deeply incised canyons that lie within the northern section of BNM. Structure contour and isopach maps derived from field observations of exposed contacts in BNM are combined with existing geologic surface and drill-hole data for the southern part of Los Alamos National Laboratory to provide a glimpse of the topography that developed prior to eruption of the Tshirege Member. The non welded Otowi Member was easily eroded, resulting in a landscape characterized by rolling hills with gentle gradients. Episodic eruptions of plinian ash and erosion of the Sierra de los Valles, accompanied by possible seismic shaking during the collapse of a portion of Rabbit Mountain, resulted in pulses of sediment that periodically overwhelmed developing drainage systems. Regional base level was controlled by the ancestral Rio Grande, whose location shifted in response to silicic volcanism from the Jemez Mountains to the west, mafic flows from the Cerros del Rio volcanic field (~3.0-1.1 Ma) to the east, as well as probable seismic activity within the rift. The mafic flows created a resistant tableland which provided local knickpoints for streams draining the Otowi headlands, allowing broad washes to form adjacent to the master stream. In addition, continuing eruptive activity, occasional landslides, earthquakes, and undercutting of the ancestral Rio canyon","PeriodicalId":435999,"journal":{"name":"New Mexico Geological Society, 2008 Annual Spring Meeting, Proceedings Volume","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131301281","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}

Connell","doi":"10.56577/sm-2008.866","DOIUrl":"https://doi.org/10.56577/sm-2008.866","url":null,"abstract":"The Albuquerque Basin of the Rio Grande rift was the subject of intensive multiagency geologic and hydrogeologic study beginning in the 1990s. A focus of geologic study was on new mapping to better describe and understand the Santa Fe Group basin-fill aquifer system, which currently provides much of the region’s supply of water. Results of these geologic studies led to the creation of a refined stratigraphy that incorporated subsurface data and improved age control. This work illustrated how the structural geometry and geomorphic evolution of this basin influenced the spatial distribution of rock types and faults and explained why parts of this basin possess more productive water-supply wells than others. The Albuquerque Basin is segmented into smaller complexly faulted half-graben sub-basins by strain accommodation zones. Rifting began in late Oligocene time with the creation of segmented, internally drained sub-basins that were dominated by fluviolacustrine and eolian sediments. By late Miocene time, sandier fluvially dominated extrabasinal sediments associated with the ancestral Rio Grande reached the northern part of the basin and ended in playa lakes at the southern end. By early Pliocene time, this axial river flowed through the basin and into southern New Mexico. By Plio-Pleistocene time, the axial-river load had coarsened and migrated towards the present position of the Rio Grande valley, where it incised to form a continuous river valley. In the Albuquerque-Rio Rancho area, the western basin-margin is structurally high and potable groundwater is mostly derived from consolidated and calcite-cemented Miocene sediments. This structurally high western flank also provides shallower targets for petroleum development in the subjacent Mesozoic strata. The structurally lower eastern part of the basin under Albuquerque contains younger, coarser, and thicker Plio-Pleistocene strata that produce some of the largest yields and generally higher quality groundwater in the region. An unconformity locally aids in differentiating between the less productive Miocene and more productive Plio-Pleistocene deposits. As potable water sources become scarce, abundant brackish-water resources may become attractive production targets for desalination along the structurally higher","PeriodicalId":435999,"journal":{"name":"New Mexico Geological Society, 2008 Annual Spring Meeting, Proceedings Volume","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125978002","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}

We studied rocks that outcrop along County Road 65 in the Gallinas Canyon, which dissects a portion of the batholith. Major rock types include quartzofeldspathic gneisses and laminated amphibolites. The felsic gneisses contain microcline + albite + quartz ± biotite in a medium- to coarse-grained anhedral granular texture. Muscovite is rare and often secondary in origin. The felsic gneisses commonly display quartz ribbons and microcline porphyroclasts and are interpreted as metagranites. They have Rb- (Y+Nb) and Nb-Y variations indicative of volcanic-arc-granites. The mafic gneisses contain hornblende + plagioclase + quartz + titanite ± epidote and display a fine to medium-grained subhedral granular to idioblastic texture. They show igneous differentiation trends on Niggli variation diagrams and are interpreted as metabasalts. They plot as island arc tholeiites and ocean island arc basalts on tectonic discriminant diagrams. The granite gneisses and amphibolite gneisses are interpreted as part of an arc system that was accreted to North America during the assembly history of the continental lithosphere. The bimodal nature of igneous activity suggests a magmatic rift may have been operative during their formation. We continue to analyze our data to see if differentiation of the proposed rift setting (juvenile or continental) is possible and test whether our data are consistent with an arc accretion model or if an expanded model including crustal extension is required.","PeriodicalId":435999,"journal":{"name":"New Mexico Geological Society, 2008 Annual Spring Meeting, Proceedings Volume","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132013433","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}

We used a statistical approach to resolve size classes (= age groups) in clavicles and interclavicles from which we generated a growth curve and age distribution for Buettneria . Comparison of these data to extant salamander outgroups (e.g., Andrias, Cryptobranchus, Chioglossa , others) and other amphibians showed that growth was indeterminate and that only sexually mature (marked by size, slow linear growth, and age distribution shape) adults were present in the fossil assemblages. They lived, on average, 10 or 11 years past sexual maturity. Linear size (measured by skull and femur length) increased by a factor of ~1.9 between sexual maturity and death, similar to the outgroups. Juvenile Buettneria are recognizable at very small sizes elsewhere in the Chinle Group, but are not present in these assemblages and are very rare in the fossil record even though population dynamics dictates that they must greatly outnumber adults. Where were the juveniles? Analysis of the Rotten Hill population showed that the diameter of Buettneria’s limb bones grew in strong negative allometry; e.g., the allometric constant for femur length versus midshaft diameter = 0.78, where a constant of 1.5 is required to maintain","PeriodicalId":435999,"journal":{"name":"New Mexico Geological Society, 2008 Annual Spring Meeting, Proceedings Volume","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127945045","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}
