assemblages of minerals are typically associated with the formation of each of the three major rock types—igneous, sedimentary, and metamorphic rocks. Plate tectonics (see fig. 1) play a major role in the processes of mineral and rock formation. In geologic terms, a plate is a large, "rigid" slab of solid rock. The word tecton

Nov 20, 2009· The Promise and Perils of Seafloor Mining. Hot, buoyant, mineralladen fluids rise from deep within ocean crust and mix with cold seawater. That triggers the precipitation of minerals that form deposits near and on the seafloor. Precipitating minerals also form seafloor "chimneys," and mineral particles in the fluids venting at the seafloor ...
