Metamorphic rock, Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form" The original rock is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (100 megapascals (1,000 bar) or more), causing profound physical or chemical changeThe protolith may be a sedimentary, igneous, or existing metamorphic rockTectonostratigraphic subdivisions of the Himalaya: A ,, [1964, 1981] included metamorphic Indian plate rock of Pakistan in the HHC but did not extend the MCT Yeats and Lawrence  concluded that neither the MCT nor the HHC extend west of the syntaxis region and that the metamorphic zone in Pakistan more closely resembles rockConstraints on the Tectonic Evolution of the Northwestern ,, Petrologic, geochronologic, and structural studies of Indian-plate rocks in the footwall of the Main Mantle Thrust indicate that peak metamorphism occurred in thrust imbricates well before the final assembly of the Kohistan island-arc with the Indian plate As the northern margin of the Indian plate was thickened by this early thrusting, the metamorphic rocks evolved along increasing pressure .Petrology and geochemistry of amphibolites and ,, Petrology and geochemistry of amphibolites and greenschists from the metamorphic sole of the Muslim Bagh ophiolite (Pakistan): implications for protolith and ophiolite emplacement , ophiolitic metamorphic rocks, from garnetiferrous amphibo-lites to the non-metamorphosed sediments, is ,List of minerals, This is a list of minerals for which there are articles on Wikipedia , of all mineral names, see List of minerals (complete) A Edit Allophane from Graphic Mine, New Mexico, USA , Anyolite (metamorphic rock - zoisite, ruby, and hornblende) Aquamarine ..
