The relationship between fluids and mountain-belt formation within the Sevier Fold-Thrust Belt, Wyoming<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Fluid migrations affect both orogenic evolution and the rheological, mechanical, and geochemical properties of rocks. I use O, C, H isotopes, fluid inclusion thermochronology, field mapping, and structural analysis to study (1) what drives fluid migration through and out of fold-thrust belts, (2) the origin of fluids, and (3) migration paths. The aim is to develop a robust model of the relationship between fluid migration and mountain-belt formation. Future research directions include determining the timing of major deformation events using U-Pb LA-ISPMS dating of calcite veins related to fluid migrations.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n

Analog modeling of structural evolution<\/h2>\n\n\n\n

Current work, using sandbox or claybox models, focuses on the energy balance and deformation mechanisms of duplex formation in fold-thrust belts, characterizing the structural and geo-mechanical conditions under which duplexes form.

Determining structural controls on subsurface coal fires<\/h2>\n\n\n\n

The Centralia Mine subsurface coal fire acts as a case study to build an understanding of the propagation of subsurface coal fires; we use this understanding to develop new coal-fire mitigation techniques. Thousands of coal fires are currently burning around the world, producing not less than 3% of the world\u2019s estimated annual carbon dioxide emissions, in addition to being environmentally and socially devastating locally.<\/p>\n<\/div><\/div>\n\n\n\n
