Fluid inclusion studies on the porphyry-type ore deposits at Bingham, Utah, Butte, Montana, and Climax, Colorado
Data are given on the composition, temperature, pressure, and density of the hydrothermal fluids present in the central Cu-Mo core of the deposit at Bingham, Utah, and in its related but not necessarily coeval peripheral Pb-Zn deposits. These data are based on a study of primary and secondary fluid
Aqueous geochemical dynamics of metals and rare earth elements in an acid rock drainage-impacted alpine watershed
Numerous mountain watersheds in the Colorado Mineral Belt (CMB) are impacted by acid rock drainage (ARD) and acid mine drainage (AMD), which mobilize metals and rare earth elements (REEs) into surface waters. In the upper Roaring Fork watershed near Independence Pass, natural ARD from a highly miner
