Skarns can be subdivided depending on specific criteria. One way to classify a skarn is by its protolith. If the protolith is of sedimentary origin, it can be referred to as an exoskarn and if the protolith is igneous, it can be called an endoskarn. [3][4]

Depósitos tipo skarn: endo y exoskarn El endoskarn ocurre principalmente en la periferia de los plutones intrusivos donde el flujo de Fuidos fue hacia adentro del plutón o paralelo al contacto de éste.

they replace. The terms exoskarn and endoskarn were originally applied to replacements of carbonates and intrusive rocks, respectively, in contact zones where the intrusive rock was presumed to be genetically related to the skarn-forming fluids. Some authors have advocated applying the term endoskarn to skarn

Apr 23, 2023 · If sakarn protolith is sedimentary origin, it can be reffered to as an exoskarn. If the protolith is ignouse rock, it can be called an endoskarn. Skarn also classification can be made based on the protolith by observing the skarns dominant composition and the …

Jun 25, 2013 · Most of the world’s economic skarn deposits are exoskarn. A skarn is basically an envelope or halo of alteration around a granite intrusion. While this alteration can extend for several kilometers, the mineralized portion is usually much, much smaller.

Mar 1, 2018 · Exoskarn formed by replacement of limestone, and consists mainly of andraditic garnet and diopsidic pyroxene (Fig. 4 c, d, e and f), and typically is massive in texture. Exoskarn is more widely developed than endoskarn. In general, …

Jan 1, 2005 · Skarn deposits are one of the more abundant ore types in the earth’s crust and form in rocks of almost all ages. Skarn is a relatively simple rock type defined by a mineralogy usually dominated by calcsilicate minerals such as garnet and pyroxene.

A skarn formed at and outside the intrusion which produced them, and are alterations of wall rocks.
