About Calc-skarnHide

A high to medium-temperature skarn consisting mainly of granditic garnet, salite (to ferrosalite or/and johannsenite-rich pyroxene), wollastonite or Mn-rich pyroxenoids and formed at the contacts of magmatic (or other silicate rocks) with calcium carbonate rocks. It can replace former magnesian-skarns (in hypabyssal or subvolcanic conditions.) Typically calc-skarns may host ores of Fe, base metals, Cu, W, Mo, Be, B, U, REE.
