Skarn is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates. Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

Skarns or tactites are coarse-grained metamorphic rocks that form by replacement of carbonate-bearing rocks during regional or contact metamorphism and metasomatism.

Rocks with only minor deformation may be called "schistose," for example "schistose sandstone," "schistose rhyolite," etc., but these are not properly metamorphic rocks. Phyllite is intermediate between slate and schist.

Skarns are silicate rocks produced by the interaction between the hot hydrothermal fluids released by crystallizing magma with carbonate rocks – a process known as metasomatism.

A picture gallery of metamorphic rocks including amphibolite, gneiss, hornfels, marble, novaculite, phyllite, quartzite, schist, skarn, slate and soapstone.

Features of Schist and Skarn are listed here.

Nov 2, 2007 · Navachab represents a reduced distal and Mn-enriched gold skarn formed in banded, predominantly calcite marble with biotite schist and calc-silicate layers. Regional metamorphism of these rocks produced preferred growth of garnet in pelitic layers and of clinopyroxene in carbonate layers.

The skarn areas of Ginevro and Sassi Neri differ from all other Elbanean skarns. The amphibole (Fe-Pargasite) dominated skarns are characterized by veinlets (with bleached quartz-bearing rims and epidote minerals in the center), penetrating the surrounding Calamita Schists.

Dec 1, 2019 · Depending on the original modal compositions of the skarns and their host rocks, the mineralizing fluid selectively added and removed elements, which resulted for the skarns and the schist ore in a general enrichment in Sn, In, Cu, and W and a …

When we have to compare Schist vs Skarn, the texture, color and appearance plays an important role in determining the type of rock. Schist is available in black, blue, brown, dark brown, green, grey, silver colors whereas, Skarn is available in black, …
