burial metamorphism. (geology). A kind of regional metamorphism which affects sediments and interbedded volcanic rocks in a geosyncline without the factors of orogenesis or magmatic intrusions. 1  Facebook. 2  Twitter.
Since varied temperature and pressures will produce different minerals, the exact type of metamorphic rock produced depends on the grade (intensity) of metamorphism. The grade of metamorphism can most often be determined by the minerals present within the metamorphic rock and the type of rock formed. Some of the more common metamorphic minerals include quartz, feldspar, biotite, muscovite, chlorite, garnet, tourmaline, calcite, and amphibole.
