What metals are found in seafloor massive sulfide deposits?

The Woods Hole Oceanographic Institution is dedicated to advancing knowledge of the ocean and its connection with the Earth system. A new theory that gives promise of eventually relating geomagnetism and the earth's internal and orbital dynamics. Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes ... Feb 24, 2012 ... Reveals how seafloor topography, magnetic polarity, and age are evidence for the sea floor spreading hypothesis. This activity consists of naming the continents, identifying mid-ocean ridges, and determining the age of the ocean floor. Because of this, the youngest sea floor can be found along divergent boundaries, such as the Mid-Atlantic Ocean Ridge. The spreading, however, is generally not ... Mar 2, 2017 ... Abstract ... Asymmetric seafloor spreading is indicated by the distances spanned over Chron intervals for the western and eastern flanks of the ... Oct 2, 2015 ... Mid-ocean ridge volcanism and extensional faulting are the fundamental processes that lead to the creation and rifting of oceanic crust, ... Mar 30, 2016 ... The magmatic, tectonic, and hydrothermal processes forming the oceanic crust along mid- ocean spreading centers are strongly modified at ... Seafloor spreading determines plate motion around a midocean ridge. Midocean ridges are always plate boundaries. Since many plates, such as the North American ...
