Available in PDF, EPUB and Kindle. Book excerpt: Geologic mapping in Imogene Basin two miles south of the portal of Camp Bird Mine No. 14 level shows a thick section of volcanic rocks composed of lithic tuff breccias of latite to rhyodacite and welded ash-flow tuffs of andesite to latite. Mine workings which are generally in the San Juan Formation, penetrate the volcanic rocks to the underlying Telluride Conglomerate and Cutler Formation. Camp Bird vein trends east-west across the thesis area and is intersected by several northwest-trending veins and dikes. Some veins terminate at Camp Bird vein while others cut across this vein structure. Detailed mapping (1:240) of Camp Bird vein shows that mineralization occurs as three distinct vein components: (1) an early quartz-sulfide component (2) quartz breccia component and (3) bull quartz vein filling. These components exhibit different structural relations that indicate the type of caldera activity that occurred during vein mineralization. Early mineralization occurs filling long continuous tension openings while later mineralization fills open, probable cymoid loop structures created by lateral movement along the vein structure. Petrographic and geochemical analysis of wall rock samples collected adjacent to the Camp Bird vein show that alteration and trace metal dispersion related to vein mineralization extend into the hanging wall and footwall to a depth of about 15 feet. Alteration includes addition, by replacement of quartz, sericite and calcite into the hanging wall. Trace metal dispersion associated with Camp Bird vein generally extends less than fifteen feet into the wall rock. It is most pronounced in the footwall. Progressing away from the vein, Cu, Pb, Zn and Ag show a rapid decrease to background levels while Mn shows a more erratic decrease.
