The current deficits of snowpack, precipitation and streamflow are occurring within a context of increasing temperature that is projected to continue into the foreseeable future. So what is the future of streamflow in New Mexico? Hydrologic models forced by global climate models provide us with a powerful, but still limited, means for making projections of streamflow on seasonal and longer time scales. We will present an overview of the projected future of streamflows in the major snow-fed rivers of New Mexico in the 21st Century, looking backward in time to assess the models and forward in time to examine scenarios of the future.","PeriodicalId":363585,"journal":{"name":"Proceedings Volume: \"Hydrology and History of the Rio Grande\", New Mexico Geological Society, 2013 Annual Spring Meeting","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128468268","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}

McLemore, N. Dunbar, Annelise M. Riggins","doi":"10.56577/sm-2013.65","DOIUrl":"https://doi.org/10.56577/sm-2013.65","url":null,"abstract":"Numerous occurrences of brick-red, K-feldspar-rich rocks, called episyenites, were discovered in the Caballo and Burro Mountains during exploration for U in the 1950s and 1960s. The term episyenite, as used by Leroy (1978), describes rocks that were desilicated and metasomatized by alkali-rich fluids solutions, possibly related to alkaline or carbonatite magmas. The episyenites in the Caballo and Burro Mountains replace the original Proterozoic igneous granites, granodiorites, and gneissic granites, and contain as much as 16% K2O and have higher concentrations of REE (<1378 ppm total REE), Th (<9721 ppm) and U (<2329 ppm) than most igneous rocks. Field observations and mapping indicate that these episyenites are typically found as flat-lying pods or lenses (<300 m in diameter), pipe-like bodies, and dike-like bodies (<2 m wide and 400 m long). They consist of K-feldspar with varying amounts of quartz, muscovite, hematite/goethite, chlorite, and plagioclase. Accessory minerals include apatite, zircon, calcite, fluorite, limonite, magnetite, barite, and malachite. Some areas have numerous small episyenite bodies in a geographically restricted area, suggesting fracture or fault control. The contacts between the episyenite bodies and the host rocks vary from location to location, from very sharp to distinctly gradational. In places where the contacts are sharp, the episyenites could be interpreted as intrusive primary igneous rocks. However, gradational contacts are more typical. A striking example is the episyenite body located in the Jack Creek rapakivi granite, in the Ramsey Saddle area of the Burro Mountains, which exhibits a strongly gradiational contact, transitioning from the buffcolored host rapakivi granite to brick-red episyenite over a distance of 10s of meters. The large rapikivi feldspar crystals, diagnostic of the host granite, are overprinted by the brick-red episyenite, indicating that a fluid-driven metasomatic process was responsible. Similar replacement relationships are observed in other localities, and are reinforced by microbeam observations of feldspar crystal texture and composition (see Riggins et al., this volume). Although multiple origins for episyenite are possible (i.e., igneous and metasomatic), the simplest explanation for the field relationships is that these similar occurrences of brick-red episyenites are all metasomatic in origin. In other geological occurrences of similar types of metasomatic alteration elsewhere in the world, alkaline or carbonatite magmas are thought to be the origin of the REE-bearing metasomatic fluids. Elsewhere in New Mexico, episyenites are found in the Nacimiento Mountains, Pedernal Hills, Lobo Hill, and Zuni Mountains. CambrianOrdovician carbonatites are found in the Lemitar and Chupadera Mountains, Lobo Hill, Monte Largo (Sandia Mountains) and southern Colorado (Wet Mountains and Iron Mountain); and CambrianOrdovician alkali syenites are found in the Florida Mountains.

Williamson","doi":"10.56577/sm-2013.56","DOIUrl":"https://doi.org/10.56577/sm-2013.56","url":null,"abstract":"New 40Ar/39Ar dating of a key ash horizon and detrital sanidines from the San Juan Basin, NM (SJB) demonstrate that the lower part of the Ojo Alamo formation (Naashoibito) is not older than 66.5±0.2 Ma thereby revising down some earlier age estimates by ~2-3 Ma. In addition, a 65.70±0.03 Ma sanidine date from the Nacimiento Formation that stratigraphically overlies a recently reported U/Pb date of a dinosaur bone at 64.8±0.9 Ma challenges the accuracy of the U/Pb system to directly date bones. The SJB strata holds a globally important record of mammal and dinosaur evolution and extinction, but the lack of a precisely and accurately determined chronostratigraphy limits complete understanding of this record. We use a combination of high precision detrital sanidine dates from Cretaceous and Paleocene strata and a newly discovered ash layer to advance our understanding of this record. Three samples of the dinosaur-bearing Naashoibito member yields variable detrital sanidine age populations. The youngest group of one sample is 66.5±0.2 Ma and variations between age populations could indicate unconformities or variable provenances in the Naashoibito. A depositional age at no greater than 66.5 Ma demonstrates that the Naashoibito's mammal fauna, the Alamo Wash local fauna, are significantly younger than earlier suggestions of 69 Ma. Three samples (2 sandstones, 1 ash) at stratigraphically similar levels within the Nacimiento Formation in the De-na-zin Wilderness area record concordant ages. The ash is 65.70±0.03 Ma (n=59 of 61 sanidines). The fact that the two sandstone samples contain minimum detrital populations that are equal in age (65.78±0.11, 65.62±0.07 Ma) to the ash demonstrate that detrital sanidine can yield the depositional age of sedimentary rocks. These units are stratigraphically above a U/Pb dated dinosaur bone (64.8 ± 0.9 Ma) and thus are not compatible. We suggest that the U/Pb date is not accurate and the dinosaur bone cannot be younger than 65.7±0.03 Ma. Importantly, this 65.7 Ma ash occurs between the fossil horizons that yield middle and late Puercan age fossils. This places significant and surprisingly old age constraints on Puercan faunas if the K-Pg boundary is 66.0 Ma. At Mesa de Cuba, detrital dating of a layer ~61 m above the Ojo Alamo (OA) contact gives a maximum depositional age of 64.24±0.30 Ma. This age and error suggests a depositional rate between 17 and 36 m/m.y. and would place the top of the OA between 65.9 and 67.8 Ma and consistent with the youngest found detrital sanidines in the OA. This further indicates that the OA is significantly less than 69 Ma. Ar/Ar data are at 1σ, relative to a 40K total decay constant of 5.543-10/a and Fish Canyon sanidine at 28.294 Ma.","PeriodicalId":363585,"journal":{"name":"Proceedings Volume: \"Hydrology and History of the Rio Grande\", New Mexico Geological Society, 2013 Annual Spring Meeting","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127783893","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}

Thin, cross-bedded layers of pumice above the jawbearing bed are geochemically identical to Group II pumices in ARG sediments between 1.2 and 1.6 million years in age (Cerro Toledo eruptions of Jemez volcanic field) studied in Hell Canyon. The ARG deposits underlie thick fan deposits of Qvo3, which forms the surface at the Socorro County fairgrounds and airport. This fan surface is traceable down the arroyo to ancestral Rio Grande terrace deposits, 30 m above the modern Rio Grande floodplain and is traceable up Matanza Arroyo to a terrace along Socorro Canyon Arroyo. In 2003, Phillips et al. determined a Cl age of 122 ± 18 ka for this terrace. Although the upper surface and shallow deposits of Qvo3 likely are equivalent to the age of the Qvo3 terrace in Socorro Canyon, the stratigraphy of the alluvium and soils between the jaw and the fan surface suggests a long history of erosion, deposition, and stability.","PeriodicalId":363585,"journal":{"name":"Proceedings Volume: \"Hydrology and History of the Rio Grande\", New Mexico Geological Society, 2013 Annual Spring Meeting","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134646598","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}
