Fluid inclusion and metal ratio analysis of Cordilleran Pb-Zn-Cu-(Ag-Au) veins of the Montezuma district : Summit County Colorado, USA
MetadataShow full item record
Evidence from fluid inclusion microthermometry in Pb-Zn-Cu-(Ag-Au) veins and district scale metal ratio zonation analysis indicate that the Cordilleran veins of the Montezuma mining district Summit County, Colorado, USA are indicative of subepithermal setting about a central hydrothermal source. Cordilleran-type polymetallic mineralization is a class of ore deposits that are spatially and temporally related to felsic igneous centers and can also be genetically related to porphyry mineralization (Fontboté and Bendezú, 2009). At Montezuma, the Teritary-aged Montezuma Stock is cross cut by several ...
