Modeling Hydrocarbon Microseepages and Related Alterations by Spectroscopy and Hyperespectral Remote Sensing Long-term leakage of hydrocarbons microseepages develop diverse array of chemical and mineralogical changes in the form of alterations in rocks and soils.The resulting alterations can include; the formation of kaolinite, calcite, pyrite, uraninite, elemental sulfur, and certain magnetic iron oxides and iron sulphides, bleaching of red beds, clay mineral alteration, electrochemical changes, radiation anomalies, geomorphic anomaly etc. We are developing new methodologies to use spectroscopy, hyperspectral remote sensing data and geochemistry data to identify and map the alterations caused by hydrocarbon microseepages in the Lisbon Valley, Utah and Patrick Draw area, Wyoming
