Non-Foliated Metamorphic Rocks
Non-foliated metamorphic rocks do no longer have a platy or sheet-like shape. There are numerous ways that non-foliated rocks may be produced. Some rocks, including limestone are product of minerals that aren’t flat or elongate.
Skarn
Skarn is coarse-grained metamorphic rocks that forms by a metasomatism. Also called tactites. Skarn tend to be rich in calcium-magnesium-iron-manganese-aluminium silicate minerals that also...
Marble
A granular metamorphic rock, marble is derived from limestone or dolomite. It consists of a mass of interlocking grains of calcite or the mineral dolomite. Marbles form when limestone buried deep in the older layers of Earth’s crust is subjected to heat and pressure from thick layers of overlying sediments.
Quartzite
Quartzite is a nonfoliated metamorphic rock composed almost absolutely of quartz. It paperwork while a quartz-rich sandstone is altered via the warmth, pressure, and chemical interest of metamorphism. These situations recrystallize the sand grains and the silica cement that binds them collectively. The result is a network of interlocking quartz grains of incredible power.
