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

现在暴露在地球表面的古代岩石使地质学家得以一窥控制它们形成的过程，并使维持我们目前生活水平的金属矿床得以产生。在加拿大地盾，裸露的岩石记录了一个漫长而复杂的历史，涉及岩浆作用、变质作用、变形作用和矿化作用的相互作用。地质学家通过检查矿物学、结构、矿物化学和同位素比率的变化来重建这些岩石的起源和演化。反过来，这些信息使我们能够建立概念模型和方法来解释在各种不同构造环境中形成的岩石的起源和演化。金属矿床的分布和矿物学特征可以在一个强大的地质、地球化学和同位素框架的背景下确定。

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.
