METAMORFNE KAMNINE / METAMORPHIC ROCKS

Očesni gnajs je metamorfna kamnina pri kateri so zaradi dodatnega stranskega tlaka zbirno kristalila v obliki večjih valjastih skupkov zrn glinencev, ki jih v preseku vidimo kot »očesa«, in so obdana s temnejšimi minerali.

Augen gneiss is a metamorphic rock in which the mineral grains have collectively crystallised in the form of larger cylindrical aggregates of clayey grains, which are visible in cross-section as "eyes" and are surrounded by darker minerals due to additional lateral pressure.

Serpentinit je zelenkasta, lahko tudi skoraj povsem temno zelena ali skoraj črna metamorfna kamnina, ki je nastala pri metamorfozi ultramafičnih magmatskih kamnin Zemljnega plašča in jo sestavljajo predvsem serpentiniziran mineral olivin ter minerali iz skupine rombičnih piroksenov.

Serpentinite is a greenish, almost completely dark green, or almost black metamorphic rock formed during the metamorphism of ultramafic magmatic rocks in the Earth's mantle, and is composed primarily of the serpentinite mineral olivine and minerals from the rhombic pyroxene group.

Eklogit je metamorfna kamnina, nastala pri izjemno visokih tlakih, ki jo sestavljajo zelen omfacit, rdeči granati, pa tudi moder kianit ter drugi minerali. Najtemnejši zrna so amfiboli, ki so posledica retrogradne metamorfoze, ko so se pirokseni ob prisotnosti vode spremenili v amfibole.

Eclogite is a metamorphic rock composed of green omphacite, red garnets, blue kyanite, and other minerals formed at extremely high pressures. The darkest grains are amphiboles, formed by retrograde metamorphism of pyroxenes to amphiboles in the presence of water.

Kalcitni marmor je metamorfna kamnina, ki je nastala pri metamorfozi sedimentne kamnine apnenec.

Calcite marble is a metamorphic rock that formed as the sedimentary rock limestone metamorphosed.

Blestnik je skrilava metamorfna kamnina, ki jo sestavljajo bleščeči kristali sljud, sivkasti kremen in beli plagioklazi.

Mica schist is a shale metamorphic rock with lustrous mica crystals, greyish quartz, and white plagioclase.
