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...
Phyllite
Phyllite is a foliated metamorphic rock that has been low pressure and heat. Phyllite formation from slate that is further metamorphosed so that very fine grained mica mineral achives. It composed of mainly flake-shaped mica minerals. This mica minerals is strong parallel alignment, so easly to split into sheets or slabs. Also alignment of mica grains gives a reflective sheen on phyllite. Generally Phyllite is gray, black or greenish color and frequently weathers out of a tan or brown.
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.
Slate
Slate is a fine-grained, foliated metamorphic rock this is created via the alteration of shale or mudstone by means of low-grade local metamorphism. It is famous for a extensive form of makes use of such as roofing, floors, and flagging due to its sturdiness and appealing look.
