This book was released on 2014 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subsurface characterization of three-dimensional structural traps is becoming increasingly important with the advent of new technologies for the sequestration of anthropogenic carbon dioxide, which often takes place within preexisting, sealed reservoirs to permanently store greenhouse gasses that are detrimental to the global climate. Within the Big Snowy Arch, central Montana, reservoir units that are targets for carbon sequestration have experienced Laramide and younger deformation and widespread Eocene igneous activity, which introduced a heating mechanism for hydrothermal fluid flow and created anisotropy in Mississippian strata. One particular region of interest is the western flank of the Big Snowy Mountains, which contains a northeast-southwest striking, high-angle fault zone which has acted as a conduit for hydrothermal brine solutions into the overlying Phanerozoic rocks. Such fault zones often branch and bifurcate as they propagate up-section through the overburden, until a loss of thermally-driven hydrodynamic pressure terminates the upward movement of carbon dioxide-rich brines, leaving a distinct assemblage of collapse breccia rich in hydrothermal minerals, such as saddle dolomite and sulfide precipitates. To determine the degree of structurally-induced anisotropy within the reservoir units, field techniques (detailed structural measurements and lithologic descriptions) coupled with analytical methods (X-ray diffraction spectrometry, stable carbon and oxygen isotope analyses, secondary electron imagery, and petrography) were utilized. These techniques presented concrete evidence of hydrothermal mineralization and episodic fluid flow within the brecciated region of the fault zone. These areas are major avenues of enhanced porosity and permeability in the subsurface, which has important applications at some sites in Montana where carbon sequestration is under consideration (e.g., Kevin Dome).

Available in PDF, EPUB and Kindle. Book excerpt: Paleozoic and Precambrian rocks intersected deep in Continental Scientific Drilling Program corehole VC-1, adjacent to the late Cenozoic Valles caldera complex, have been disrupted to form a spectacular breccia sequence. The breccias are of both tectonic and hydrothermal origin, and probably formed in the Jemez fault zone, a major regional structure with only normal displacement since mid-Miocene. Tectonic breccias are contorted, crushed, sheared, and granulated; slickensides are commmon. Hydrothermal breccias, by contrast, lack these frictional textures, but arej commonly characterized by fluidized matrix foliation and prominent clast rounding. Fluid inclusions in the hydrothermal breccias are dominantly two-phase, liquid-rich at room temperature, principally secondary, and form two distinctly different compositional groups. Older inclusions, unrelated to brecciation, are highly saline and homogenize to the liquid phase in the temperature range 189 to 246°C. Younger inclusions, in part of interbreccia origin, are low-salinity and homogenize (also to liquid) in the range 230 to 283°C. Vapor-rich inclusions locally trapped along with these dilute liquid-rich inclusions document periodic boiling. These fluid-inclusion data, together with alteration assemblages and textures as well as the local geologic history, have been combined to model hydrothermal brecciation at the VC-1 site.

This book was released on 1983 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This circular covers the geology of the Pyramid Peak, Swallow Fork Peak, Table Top Mountain, and South Pyramid Peak 7-1/2-min quadrangles, which include the Lightning Dock KGRA. Hot wells (70 to 115.5°C) seem to be structurally controlled by intersections of the ring-fracture zone of an Oligocene ash-flow tuff cauldron (Muir cauldron), a Miocene-to-Holocene north-trending basin-and-range fault (Animas Valley fault), and a northeast-trending lineament that appears to control anomalously heated underground waters and Pliocene-Pleistocene basalt cones in the San Bernardino, San Simon, and Animas Valleys. The Muir cauldron, approximately 20 km in diameter, collapsed in two stages, each associated with the eruption of a rhyolite ash-flow-tuff sheet and of ring-fracture domes. Most of the hydrothermal alteration of the Lightning Dock KGRA is related to the first stage of eruption and collapse, not to the modern geothermal system. Contrary to previous reports, no silicic volcanic rocks younger than basin-and-range faulting are known; unconformities beneath rhyolite ring-fracture domes are caused by Oligocene caldera collapse, not by basin-and-range faulting. The Animas Valley is the site of widespread post-20 My travertine deposits and near-surface veins of calcite, fluorite, and/or psilomelane, controlled by north- or northwest-trending basin-and-range faults. The fluoride-bearing waters of the Lightning Dock KGRA may be a late stage of this hydrothermal activity. Distribution of Pliocene-Pleistocene basalt suggests that deep-seated basalt near the solids may be the ultimate heat source.
