Disease of the Other, A

Geologic carbon sequestration is being reviewed as a viable means to help reduce anthropogenic carbon dioxide in the atmosphere. Wyoming possesses at least eight natural analogues wherein CO2 has accumulated for a geologically significant amount of time. Natural CO2 analogues provide a means of understanding and predicting behavior in carbon repositories, particularly as test beds for investigating and improving technologies and protocols aimed at assessing the integrity of caprock formations. Successful measurement of CO2 and Rn emissions on active volcanoes demonstrates the viability of a geochemical tool to relate CO2 emissions to source regions such as deep reservoir versus shallow soil CO2 flux, and the mechanism of gas transport toward the surface. A transect was completed along Muddy Creek Road south of LaBarge, Wyoming capturing three main zones in relation to background gamma radiation and CO2 flux of the region. Moving west away from LaBarge CO2 Field, CO2 flux and 220 Rn/222 Rn ratio relatively increases as a result of tectonic activity in the region. Future research will be required to truly determine the sample variance between the relation of CO2 flux and Rn gas ratio to the tectonic activity.
