| Popis: | Most oceanic crust that has been formed over the life of our planet has been subducted, removing it from direct study. This leaves us with little record of the processes operating in, and tectonic configurations of, two-thirds of the Earth’s surface over most of geological time. Fortunately, some portions of oceanic crust are occasionally preserved as ophiolites. Although ophiolites probably form in a diverse range of geological settings they provide an important perspective on the chemical and tectonic evolution of the planet carrying information about features such as the timing and orientation of extension and the composition of the upper mantle beneath these past spreading ridges. However, we still have little idea how to interpret much of … |
