Analyzing post-flood recovery after an extreme flood : North St. Vrain Creek, CO
Assessing the ongoing sediment remobilization and deposition following an extreme flood is important for understanding disturbance response and recovery, and for addressing the challenges to water resource management. From ... -
Hydrogeologic characterization of the Fountain Formation : prospective aquifer storage and recovery targets in Front Range Colorado
Aquifer storage and recovery (ASR) is a method of water storage that typically involves using the same well to inject water into and recover water from an aquifer. Benefits of ASR include lower capital costs than surface ... -
Organic carbon storage in mountain river valley bottoms of the western United States
Valley bottoms, which include river channels and associated floodplains, are important components of the terrestrial carbon sink. Downed wood and floodplain soil in valley bottoms act as transient pools of organic carbon ... -
Floodplain organic carbon storage in the central Yukon River Basin, interior Alaska
River channels and floodplains transport, transform, deposit, and store organic carbon (OC) as active participants in the carbon cycle. Two of the largest stocks of OC in floodplains include soil and downed large wood (LW). ... -
Diagenesis and geochemistry of the Lower Permian Ingleside Formation, Owl Canyon area, Larimer County, Colorado
The purpose of this study is to determine the diagenetic history and timing of hydrocarbon migration in the Lower Permian Ingleside Formation as revealed in the Ingleside roadcut at Owl Canyon area, Colorado. The studied ... -
Hydrothermal mineralization and alteration at the Globe Hill deposit, Cripple Creek district, Colorado
The Globe Hill deposit is hosted by a porphyritic, subvolcanic intrusive which is composed of pyroxene-bearing alkali trachyte. It is emplaced within the Oligocene-age Cripple Creek diatreme-intrusive complex, which may ... -
Geology, mineralization, and fluid inclusion analysis of the Ajax vein system, Cripple Creek, Colorado
The Ajax mine is located in the Cripple Creek mining district. Teller County, Colorado. Mine workings extend through a vertical range of 3363 feet (1025 m), from 10,105 feet (3081 m) to 6742 feet (2055 m) elevation. ... -
Structural geology and tectonic setting of the Cherry Creek Metamorphic Suite, Southern Madison Range
The Cherry Creek Metamorphic Suite, exposed in the core of the southern Madison Range in the northwestern Wyoming province, is a well-preserved, carbonate-quartzite-pelite shelf association of Archean age containing a ... -
Investigating the carbonate-shale facies transition and deposition on the Scandinavian Ordovician Shelf – the Arnestad Formation, southern Norway
The Upper Ordovician Arnestad Formation was located on the northwestern edge of Baltica in the region near modern day Oslo, Norway. This formation was found to be 60 m thick and consists of intercalated siliciclastic ... -
Tracing hydrosocial change : the social constellations of water access and allocation for oil and gas development in Colorado
Increasing water use for OG development in Colorado suggests a change in the social constellations of water governance. Colorado's water allocation institutions, practices and policies relationally shape and are shaped by ... -
Facies reconstruction and detrital zircon geochronology of the Ingleside/Casper Formation
Mixed siliciclastic-carbonate deposits of the Ingleside/Casper Formation in northern Colorado and southeastern Wyoming developed along the flanks of the Ancestral Front Range during the Late Paleozoic. This study establishes ... -
Using RMS amplitudes from forward seismic-reflectivity modeling of channelized deep-water slope deposits to inform stratigraphic interpretation and sub-seismic scale architecture, Tres Pasos Formation, Magallanes Basin, Patagonia, Chile
Deep-water slope channels outcropping in the Tres Pasos Formation of the Magallanes Basin in southern Chile are used as the foundation of a forward seismic-reflectivity modeling study to better inform stratigraphic ... -
Geology of the Taylor Silver deposit, White Pine County, Nevada
The Taylor silver mine is located 15 miles southeast of Ely, Nevada, on the western flank of the Southern Schell Creek Range. The 1200 ton per day open pit mine produces up to 1,200,000 ounces silver and 1000 ounces gold ... -
Geology of the footwall of the northern Plomosa Mountains metamorphic core complex, west-central Arizona
The northern Plomosa Mountains is a N-S trending range in the lower Colorado River Extensional Corridor, west-central Arizona – a region which hosts several highly extended terrains known as metamorphic core complexes. ... -
Seismic anisotropy in northwestern Canada and eastern Alaska from shear wave splitting measurements
The Mackenzie Mountains are an actively uplifting and seismogenic mountain range that lies within the Yukon and Northwest Territories, Canada. The range is an eastward salient of the complexly deformed northern Canadian ... -
Hydrologic characterization of upper Permian-Cenozoic sedimentary strata of Larimer County : prospective aquifer storage and recovery targets
Providing adequate water storage is an on-going problem along the northern Colorado Front Range. This study compiles existing hydrogeological data from water wells to identify potential ASR sites in eastern Larimer County, ... -
Faulting in the Foam Creek Stock, North Cascade Mountains, Washington
The Foam Creek Stock (FCS) is a tonalite pluton in the northwestern part of the Nason Terrane in Washington state, a region that has experienced a wide range of structural regimes. Faults cutting the FCS have been studied ... -

Deciphering the Late Jurassic paleoenvironment through Re-Os isotope geochemistry of the Agardhfjellet Formation, Svalbard
Accurate interpretations of environmental change throughout Earth's history rely on robust correlations of sedimentary systems. The Late Jurassic has been difficult to correlate regionally and globally due to sparse ...
