Formerly, the Hell-to-Finish Formation has been considered genetically similar and correlative with the redbeds of the Glance Conglomerate and Morita Formation based on outcrop appearance and stratigraphic position. In the SW Huachuca Mountains, a detrital zircon sample from a volcanic litharenite high in the Glance Conglomerate contains dominantly Early to Middle Jurassic grains (81 of 96 grains) derived from underlying volcanic rocks. Unconformably overlying the Glance Conglomerate, the lower Morita Formation transitions from nearshore facies rocks at the base to fluvial facies rocks. A detrital zircon sample of 90 grains from a nearshore subarkose contains mostly Triassic (n=12) and Proterozoic grains (n=60) but only a few Early Jurassic grains (n=6), reflecting burial or late stage erosion of Jurassic rocks. Higher in the section, a fluvial volcanic litharenite contains abundant Cretaceous grains (ca. 145 – 120 Ma) from the arrival of volcanic material to the west. In the Little Hatchet Mountains, the lower Hell-to-Finish Formation is fluvial, and the sandstones are litharenites that contain abundant chert and carbonate clasts and no volcanic fragments. A detrital zircon sample of the Hell-to-Finish Formation is composed almost exclusively of pre-Triassic grains (78 of 79 grains) and was sourced from the Burro uplift to the north. In contrast, the Morita Formation received a significant component of material from a western source that is not reflected in the Hell-to-Finish Formation, suggesting the basins were isolated. Material for the Glance Conglomerate was locally derived and is not an input for the Hell-to-Finish Formation.","PeriodicalId":240412,"journal":{"name":"Proceedings Volume: \"Evaluating How Continental Sedimentary Basins Fill: Development and Preservation of Sedimentary Successions\", New Mexico Geological Society, 2012 Annual Spring Meeting","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131876104","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}

Weil","doi":"10.56577/sm-2012.190","DOIUrl":"https://doi.org/10.56577/sm-2012.190","url":null,"abstract":"The San Juan Basin of northwestern New Mexico is a Laramide basin that accumulated sediments through the Cretaceous-Paleogene (K-Pg) boundary. However, the precise age of the Ojo Alamo Ss which lies near the K-Pg boundary in the San Juan Basin, remains controversial. Determining its age is crucial to understanding the tectonic and biotic history near the K-Pg boundary in this area. Based on study of these strata in the Bisti/De-na-zin Wash area (BDNZ) near Barrel Springs, previous workers have argued that the top of the Ojo Alamo Ss and the base of the Nacimiento Fm are interfingering and therefore are conformable. Based on this interpretation, most workers have regarded the Ojo Alamo Ss (here regarded in the restricted sense; = Kimbeto Member) in the BDNZ to be early Paleocene in age. The base of the Nacimiento Fm has been correlated to C29n and produces early Paleocene mammals. This provides a minimum age for the underlying Ojo Alamo Ss. Given this minimum age constraint workers have generally taken one of two positions for the precise age of the Ojo Alamo Ss: (1) the Ojo Alamo Ss. spans the upper part of C29r, or (2) it is restricted to only the lower part of C29n. To resolve this question and to determine a more precise age for the Ojo Alamo Ss, we examined the stratigraphic relationships between the Ojo Alamo Ss and the overlying Nacimiento Fm in the BDNZ. Contrary to previous interpretations, we find that this formational contact is not conformable. Rather, what other workers have assumed to be the “upper part of Ojo Alamo Sandstone” that interfingers with basal parts of the Nacimiento Fm is actually a remnant of a lenticular channel sandstone of the Nacimiento Fm. This reinterpretation suggests that the formational contact between the Nacimiento Fm and the Ojo Alamo Ss may represent a significant hiatus of up to ~ 0.5 Ma separating the Ojo Alamo Ss from the base of the Nacimiento Fm in the BDNZ area. Future work should focus on more accurately determining the age and refining the duration of the hiatus at the Ojo Alamo – Nacimiento formational contact.","PeriodicalId":240412,"journal":{"name":"Proceedings Volume: \"Evaluating How Continental Sedimentary Basins Fill: Development and Preservation of Sedimentary Successions\", New Mexico Geological Society, 2012 Annual Spring Meeting","volume":"19 s28","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120833982","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}

This increased erosion and subsequent sedimentation on alluvial fans at the base of the hillslope may be the primary process of geomorphic change in fire-prone mountains in the Western US. Insolation differences on north and south facing slopes may also be another potential influence on geomorphic change due to soil moisture and vegetation differences, which may affect the spatial distribution of erosion as well as sediment transport processes. Due to the long recovery period of forest stands in fire-prone areas, it is important to understand the natural variability of erosion for the purposes of forest and river ecology and management as well as mass movement-flooding hazard. The 2002 Lakes Fire area in the Jemez Mountains, NM, provides a natural study area with incision of alluvial fans after the Lakes Fire exposing the internal structure of these fans. The study area displays steeper, drier ponderosa pine dominated south-facing slopes and less steep, moister Douglas-fir dominated north-facing slopes, which suggests that slope aspect may influence fire regime and post-fire erosion in the Jemez Mountains. In order to determine the importance of fire and aspect on erosion and sedimentation, over 15 sections within alluvial fans with both north and south aspect were studied. Debris flow, hyperconcentrated flow and stream flow make up the majority of sediment transport processes in this area. Therefore, deposits formed by these processes were described, and evidence for fire-related sedimentation was assessed. Additionally, the relative importance of sediment transport types in relation to north versus south slope aspects was examined. Finally, charcoal fragments within deposits from north and south aspects were analyzed in terms of their abundance and angularity in order to aid in estimating the severity of the fire event associated with the deposit. In this way, the importance of fire and aspect in influencing erosion and sediment transport was","PeriodicalId":240412,"journal":{"name":"Proceedings Volume: \"Evaluating How Continental Sedimentary Basins Fill: Development and Preservation of Sedimentary Successions\", New Mexico Geological Society, 2012 Annual Spring Meeting","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121042244","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}

In the San Juan Basin area of New Mexico and Colorado, the final regression of the western shoreline of the seaway was accompanied by deposition of the shoreface Pictured Cliffs Sandstone. Precise 40Ar/39Ar ages for sanidine crystals from eight altered volcanic ash beds precisely dated this regression across the San Juan Basin as beginning 76.28 Ma when the shoreline was in the southwest part of the basin and ending 73.55 Ma when the shoreline left the northeast part of the basin. (These ages are corrected from those reported in Fassett, 2000, per Kuiper et al., 2008 ? these authors assigned an age of 66.95 Ma to the K-Pg boundary vs. an age of 66.5 Ma that had been assigned earlier.) The Pictured Cliffs regression across the basin covered a distance of 145 km and took 2.73 m.y. The stratigraphic rise of the Pictured Cliffs across the basin was 384 m and thus the thickness of rock concurrently deposited was also 384 m. These precise geochronologic data make it possible to calculate the sedimentation and regression rates during the retreat of the Pictured Cliffs shoreline across the San Juan Basin.The overall average rate of sedimentation during that time, based on rock thickness, was thus about 140 m/m.y. and the average rate of regression of the shoreline was about 53 km/m.y. The decompacted 380-m rock thickness is 702 m yielding a corrected sedimentation rate of 257 m/m.y. These rates are averages, but because there are eight dated ash beds in this stratigraphic section, the rock thicknesses and time durations between these dated ashes can each be used to determine the variable rates of sediment accumulation and shoreline regression during the 2.73 m.y. it took for the Pictured Cliffs to regress across the basin. These data also make it possible to estimate the rate of tectonic subsidence and the creation of accommodation space during the PC regression; that is 114 m/m.y.","PeriodicalId":240412,"journal":{"name":"Proceedings Volume: \"Evaluating How Continental Sedimentary Basins Fill: Development and Preservation of Sedimentary Successions\", New Mexico Geological Society, 2012 Annual Spring Meeting","volume":"274 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122762819","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}

Initial finds from 1989 were the first Paleozoic vertebrate tracks from New Mexico described in detail. Currently, the New Mexico Museum of Natural History stores 167 footprint specimens from seven localities in the upper part of the Sangre de Cristo Formation in San Miguel County. A recent increase of material and knowledge necessitates revision of this ichnofauna. The assemblage comprises tracks of Batrachichnus Woodworth, 1900, Limnopus Marsh, 1894, Ichniotherium Pohlig, 1892, Dimetropus Romer and Price, 1940, Tambachichnium Müller, 1954, cf. Hyloidichnus Gilmore, 1927, and Dromopus , Marsh, 1894. They can be referred to temnopspondyl, diadectomorph, 'pelycosaur', captorhinid, and araeoscelid trackmakers. This assemblage represents a typical Early Permian red-bed tetrapod ichnofauna. Relatively large (pes length ~ 70 mm) imprints of cf. Hyloidichnus referred to moradisaurine captorhinids may indicate a late Early Permian (Artinskian-Kungurian; late Wolfcampian-Leonardian) age of the footprint-bearing strata. The remarkable abundance of Ichniotherium (referred to diadectomorphs) and Tambachichnium (referred to varanopid 'pelycosaurs') suggests that the occurrence represents an inland tetrapod ichnofauna. Such an interpretation coincides with paleogeographic reconstructions locating the study area during the Early Permian in an intramontane foreland basin (Taos trough) of the ancestral Rocky Mountains at least 160 km landward from the nearest marine shoreline. Given the rarity of fossil sites with Paleozoic inland (and upland) tetrapod communities, the Sangre de Cristo tetrapod ichnofauna is of global interest and deserves further research.","PeriodicalId":240412,"journal":{"name":"Proceedings Volume: \"Evaluating How Continental Sedimentary Basins Fill: Development and Preservation of Sedimentary Successions\", New Mexico Geological Society, 2012 Annual Spring Meeting","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131518308","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}

For high magnitude earthquakes, these waves can travel around the world and interact with other faults at great distances from where the earthquake originally occurred. This interaction through ground displacements can alter the stress state on these remote faults, reduce the friction on the faults, and cause them to fail, or trigger another earthquake. This dynamic triggering process can occur in a variety of tectonic settings but particularly occurs in areas characterized by the presence of hot fluids and/or magma. Therefore we hypothesize that triggering should be common within the region above the Socorro Magma Body (SMB) within the Rio Grande Rift. To test this, I examined data from 319 large earthquakes from around the world with magnitudes > 6.0 between January 15, 2008 and November 30, 2009 and analyzed the seismograms recorded on seismometers stationed around Socorro, NM to see if local earthquakes corresponded with the passage of waves from the large earthquake. 93 local events were found corresponding to 66 of the large earthquakes. I have been looking at background rates of seismicity in the area to determine if the amount of local earthquakes increases with the passage of large earthquake waves, indicating that some events are a result of “delayed triggering” rather than being independent of the large earthquake. The majority of local events occur above the Socorro Magma Body, showing that it is more conducive to triggering in New Mexico, but the events can be spread throughout the rift as well. We hypothesized that large earthquake locations would show a region that preferentially triggers events in New Mexico, however the only clustering of possibly triggering large earthquakes is a reflection of areas naturally more seismically active. I am also looking into triggering and triggering delay dependence on the large earthquake’s location and wave amplitude.","PeriodicalId":240412,"journal":{"name":"Proceedings Volume: \"Evaluating How Continental Sedimentary Basins Fill: Development and Preservation of Sedimentary Successions\", New Mexico Geological Society, 2012 Annual Spring Meeting","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127586391","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}
