Geology and hydrogeology of the Arroyo Seco Area, Taos County, New Mexico
This report describes the geology and hydrogeology of the southwestern Arroyo Seco quadrangle in Taos County, New Mexico. This area is approximately eight miles north of the Town of Taos and is undergoing extensive residential development. The New Mexico Office of the State Engineer (NMOSE) Hydrology Bureau has identified a need for more detailed hydrogeologic information to improve the NMOSE groundwater simulation model. To this end, I compiled existing geologic, hydrologic, and geophysical data, performed new geologic mapping, and measured water levels in 43 domestic wells. The synthesis of these data leads to an improved understanding of the distribution and flow patterns of groundwater in the area and the relation of groundwater to surface water, in addition to clarifying the geologic controls on the groundwater system.
Unearthing the Cordilleran magmatic periphery of eastern New Mexico
Currently seeking a graduate student to work on minor mid-Cenozoic igneous occurrences in eastern New Mexico, which form a patchy discontinuous belt representing the most distal periphery of Cordilleran magmatism emplaced approximately 50-200 km east of the closest major alkaline magmatic centers. They have received little attention and present excellent opportunities for exciting fieldwork, novel research, and impactful student mentorship. Initial reconnaissance of these igneous rocks is building towards holistic studies addressing basic aspects of these occurrences through mapping, petrography, geochemistry, and geochronology. This work will lead to bigger questions on the relationship between these peripheral intrusions and more major alkaline magmatic centers, exhumation and heat flow histories recorded in these rocks, and significance for tectonics of paleo-plate dynamics of the SW US Cordilleran margin!
Ignimbrite Calderas
Ignimbrite calderas are large volcanic depressions, often 10-20 miles in diameter, that form when a large-volume, gas-charged viscous magma body ejects huge columns of ash that collapse and inundate the surrounding countryside with a thick blanket of welded ash (called ignimbrite) while the shallow roof of the chamber collapses. Caldera-forming eruptions are relatively rare catastrophic events, second only in scale to large asteroid impacts. Deep magma systems that feed these "supervolcanoes" appear to march to the beat of there own drummer; eruptions are both episodic and irregular in timing and intensity.
Capillary Raman Cell Experiments: The rare earth elements are in hot water (and feeling salty)!
Somewhere in the Earth’s crust a hot fluid is seeping through tiny cracks and fissures in the rock. The fluid is water and it carries with it a cargo of dissolved ions like chloride, sulfate, or carbonate. It might also carry dissolved metal ions useful to humans such copper, gold, or, in the case that we are considering, rare earth elements (REE). Fluids like this play important roles in forming ore deposits where the REE are present in high enough amounts to be mined. We want to understand how the REE interact with other dissolved ions and the water itself in order to better understand the conditions that allow water to mobilize, transport, or deposit REE.
Uranium transport by wind-blown dust
Understanding the relationship of dust to uranium contamination can be critical to predicting if and how uranium moves by dust from a mine site, as well as predicting if the health of nearby community members and mine workers can be affected by mining activities. In this study, dust traps were installed at several locations at Jackpile Mine, a remediated uranium mine site at Laguna Pueblo, New Mexico, to evaluate this problem. In all samples, uranium levels were low, however, they were statistically high enough to help researchers determine dust influences on the movement of uranium.
