V53E:
Secondary Mineralization in Bedrock: Diagenesis, Cementation, Hydrothermal Precipitation, and the Interpretation of Paleofluid Flow II Posters


Session ID#: 11053

Session Description:
Secondary minerals precipitated in pore spaces and fractures of crystalline and sedimentary rocks record past episodes of groundwater flow, fluid mixing, and potentially biologic activity occurring long after formation of the host rocks. Changes in porosity, permeability, and composition caused by precipitation of secondary minerals have profound effects on the transport and fate of groundwater, hydrocarbons, and natural and anthropogenic supercritical fluids. Secondary mineralization also bears geochemical, isotopic, and geochronologic records of ancient groundwater flow that may constrain past climatic, tectonic, or exposure histories of crustal sections on the Earth and other planets. We welcome contributions bearing on understanding the origin and evolution of secondary mineralization in crustal rocks, their effects on hydrologic and reservoir properties, and the geologic significance of ancient secondary minerals on Earth and other planets.
