Carbonation of mafic and ultramafic rocks and mineral wastes provides a permanent way to sequester excess atmospheric CO2. Recent research has shown that this method also offers the potential for enhanced recovery of critical metals from mine tailings. This thesis presents a comprehensive study...

Mineralization in the Zacatecas district is polymetallic (Ag, Zn, Pb, Cu, and Au) and occurs as skarn-type and epithermal veins formed in different metallogenetic stages. The oldest mineralization in the district is skarn-type, Cu-rich with lesser Zn-Pb-Ag, and is considered to be close in age to...

The mid-Cretaceous Ag-Pb-Zn-Cu-Sn Keglovic deposit, located in the south-central Yukon, is formed by the superposition of an earlier Pb-Zn skarn system with later Keno Hill-style Ag-Pb-Zn veins and is the product of complex regional geological processes, which occur synchronously with...

The Appalachian orogen in eastern Canada resulted from the Paleozoic convergence of the continents Laurentia and Gondwana during the closure of the intervening Iapetus Ocean. In New Brunswick, the Fredericton Trough and Mascarene Basin were filled in the Silurian within the peri-Gondwanan domain...

The lacustrine Green River Formation (GRF) is an important oil-producing formation in the Uinta Basin, Utah (USA). In recent years, the unconventional carbonate reservoirs in the Uteland Butte member (UBM), base of the GRF, have been targeted because their estimated oil and gas resources. The...
