Publisher's Synopsis
Today, "ore" and ore deposits have become measure of mainstream geologic studies-opaque minerals can expose much about the evolution of a rock, and mineral deposits can reveal tectonic settings. Rocks and mineral deposits formed during the development of oceanic crust may, by various circumstances, arrive at the trench at the top of subduction zone. Geology has a bottom line, and that is kept in the black by discovery and assay of Earth materials. Orogenic and mobile belts are where many important ores have been formed and cyclicities have been described by the great synthesizers of geology. Plate tectonics, like crustal evolution, provides a basis for understanding the distribution and origin of mineral and energy deposits. The rigid, outer part of the earth divided into many pieces known as lithospheric plates, comprising both the continental landmasses and oceanic basins. These plates are in motion relative to each other and to the earth itself. Assuming the earth is a sphere, the motion of a plate across the earth's surface can be described as motion about the axis of a pole of rotation that goes through the centre of the earth. The intersection of the pole's axis with the earth's surface is referred to by its latitude/longitude coordinates. Metallic deposits are commonly found at both continental and arc convergent plate margins. A variety of local tectonic settings exist along collision plate margins. Most of the deposits that occur here have formed in diverse tectonic settings and have been transported to the collision zones. Mineral Deposits, Continental Drift and Plate Tectonics is devoted to different aspects of tectonic researches, especially to modern geodynamic processes. Syntheses of recent and earlier works, combined with new results and interpretations, are presented here for diverse tectonic settings and mineral deposits. Most of chapters include up-to-date materials of detailed geological-geophysical investigations, which can help more clearly understand the essence of mechanisms of different tectonic processes.
