Linking metamorphism, magnatism, and hydrothermal ore deposition in mineralized metamorphic terranes

The ancient rocks now exposed at the Earth's surface provide geologists with a glimpse into the processes that controlled their formation and gave rise to the metallic ore deposits that sustain our current standard of living. In the Canadian Shield, the exposed rocks record a long and complex history involving an interplay between magmatism, metamorphism, deformation, and mineralization. Geologists reconstruct the origin and evolution of these rocks by examining variations in mineralogy, textures, mineral chemistry, and isotope ratios. This information allows us, in turn, to build conceptual models and methodologies to interpret the origin and evolution of rocks that formed in a variety of different tectonic settings. The distribution and mineralogical character of metallic ore deposits can then be identified in the context of a robust geological, geochemical, and isotopic framework.
