Anthracite coal is considered metamorphic rock, and is derived from a bituminous coal protolith. 13 terms. It has a non-foliated metamorphic rock that has no specific composition. It may be formed simply by being deep beneath the Earth’s surface, subjected to high temperatures and the great pressure of the rock layers above it. Soapstone. ACF compatibility diagrams (aluminium-calcium-iron) showing phase equilibria in metamorphic mafic rocks at different P-T circumstances (metamorphic facies). The presence of these parallel planes of weakness makes this rock distinct from original sedimentary bedding. In this lesson, we are going to learn about metamorphic rock! Rock cycle. Metamorphic rock may be created through sedimentation or magmatism. It acts of a metamorphic rock of formed sedimentary origin mainly of clay and silica very finely crystallized (very fine granulometry). Series of processes in which rock changes from one type to another. Metamorphism can result in recrystallization of existing minerals, the formation of new minerals, and changes in the texture or fabric of a rock. What do you think a metamorphic rock is and from what might it have originated?|Do you know any metamorphic rocks? When slate forms, some of the clay from the original rock is replaced by the mineral mica. Metamorphic rocks result from the alteration of pre-existing rocks caused by heat and/or pressure produced by plate movements or intrusion of magma within the Earth's crust. They represent an expanded mass formed by metamorphic transformation (serpentinization) of peridotites. Marble is a metamorphic rock formed from the sedimentary rock of limestone. The facies are named after the metamorphic rock formed under those facies conditions from basalt. Metamorphic Rock # 1. texture. In the gummy bear lab, we measured the gummy bears, placed them in water overnight, and then measuredagain. Fossil. mrssidibe. It is a homogeneous fine grained rock which can be split into thin or thick sheets with relatively smooth surfaces. Metamorphic Rock. 29 terms. Metamorphic rock _____. This eclogite specimen from Jenner, California, consists of high-magnesium pyrope garnet, green omphacite (a high-sodium/aluminum pyroxene) and deep … For example, shale becomes slate, sandstone becomes quartzite, and limestone becomes marble. Metamorphic facies with regard to temperature and pressure. Base your answers to questions 7 and 8 on the graph below, which shows the crustal temperature and pressure conditions under which three different minerals with the same chemical composition (Al2SiO 5) crystallize. B. Metamorphic rock is formed when earthquakes shake up the rocks so they are broken into small pieces. Weight of the overlying layer of sediment. A clue to understanding how they are formed is in their name, 'metamorphic', which suggests they have changed form.
