Fluid flow and deformation history of the Denver basin, CO region: fluid inclusions, U-Pb geochronology and isotope geochemistry of calcite-filled fracture cements in the Niobrara Formation
… faults, open stylolites) acted as conduits for fluid flow. However, little to no constraints on the origin, temperature, composition, and timing of these fluid flow events exist. We address this through analysis of fracture-filling cements in the Niobrara Formation with the integration of …

Metamorphism in the Northern Front Range, Colorado
… petrography, electron microprobe analysis, and fluid inclusion microthermometry were used to quantify the history of a high grade Proterozoic terrane exposed within the northeastern Colorado Front Range. Pressure-temperature calculations identified two blocks from different crustal levels …

Experimental Study of the PVTX Properties of the System H₂O-CH₄
… is necessary to understand the role that these fluids play in different geological environments. In this study the properties of the H₂O-CH₄ fluid system at elevated temperatures and pressures has been investigated experimentally to determine the PVTX properties of H₂O-CH₄ fluids in the P-T …

The magmatic-hydrothermal fluid history of the Harrison Pass Pluton, Ruby Mountains, NV: implications for the Ruby Mountains-East Humboldt Range metamorphic core complex and Carlin-type Au deposits
… of the HPP was a regional hydrothermal fluid event responsible for deposition of >200 Moz of Au in sediment-hosted Carlin-type deposits (CTD's) along four linear trends. Magmatic, meteoric, and metamorphic models have been invoked to explain the origin of fluids and Au for CTD's, but few …

Structural controls and diagenetic conditions associated with fluid migration on the Moab Fault, UT
Faults and fault zones can have strong effects on fluid migration within the Earth’s crust, with important implications for resource management and earthquake hazards. The research presented within this dissertation addresses the fluid migration history of the Moab Fault, Utah. Using the stable …

PVTX and Raman Spectral Properties of Fluids at Elevated Pressures and Temperatures
Fluids are associated with a wide range of physical and chemical processes in the Earth, including transporting and concentrating important ore elements such as Cu, Au, Zn, and Pb. Significant amounts of fluid may be generated as a result of dehydration or decarbonation reactions, and the volatile …

Physical and chemical aspects of fluid evolution in hydrothermal ore systems
… physical model describing two-phase fluid flow is used to simulate the effect of boiling on silica precipitation in geothermal and epithermal precious metal systems. The extent to which decreasing temperature and fluid vaporization are responsible for quartz precipitation is dependent …

Paleofluid Flow, Fracturing and Reservoir Implications in Foreland basins: an example from the Cretaceous Qamchuqa Formation, Kurdistan Iraq
… controlled and affected by hydrothermal fluid flow and represent one of the major and important reservoir rocks in the High Folded oilfields. An integrated study combining field observations, core descriptions, microstructural analysis, petrographic study, stable C, O and Sr isotopes, …
