The greater the pressure or heat, the more likely the shale will change into gneiss. For example, shale (a sedimentary rock) can be transformed into slate, schist, or gneiss, depending on the degree of metamorphism. The sedimentary rocks are formed predominantly from weathered rocks or broken rock fragments. 0 0. Due to geological changes, a metamorphic rock of the foliated or nonfoliated type will be created. rock exposed to high-grade metamorphic conditions will differ from the same parent rock exposed to intermediate or low-grade conditions in both texture and mineral content - (though not necessarily in wh-rock chemistry). Temperatures involved in the formation of anthracite fall into the metamorphic range of ~200 to ~270°C. Anthracite is a high-rank coal, representing a coal that has been subjected to the highest grade of metamorphism. "Friction and distortion" caused by the movement of the tectonic plates under the earth's surface or the introduction of hot magma to the parent rock. parent rock = shale or basalt-Anthracite coal Foliated “prograde metamorphism”= alignment of platy minerals due to differential stress-Shale splits easily along flat, parallel planes o Forms from volcanic ash-Phylite newly formed micas-Schist parallel – oriented materials-Gneiss.
