Skarn rock is primarily used in the mining and Metallurgy industries, as it often contains valuable minerals such as copper, gold, and tungsten. The unique composition of skarn can also make it useful as a construction material, particularly in the production of concrete and aggregates. Additionally, skarn formations can serve as important geological indicators for the presence of mineral deposits, aiding exploration efforts.
limestone and granite
Skarn is metamorphic.
Skarns are typically composed of minerals such as garnet, pyroxene, amphibole, epidote, and scapolite. They can also contain sulfide minerals like pyrite, chalcopyrite, and sphalerite, as well as carbonate minerals like calcite and dolomite. The exact chemical composition of a skarn can vary depending on the specific parent rock and the alteration processes that have occurred.
The metamorphosed limestone will most likely be a skarn or marble, both formed from contact with an intruding granitic magma.
Skarns are most often formed at the contact zone between intrusions of granitic magma bodies and carbonate sedimentary rocks such as limestone and dolostone.
Limestone doesn't normally have a parent rock. One exception to this may be a detrital limestone, whose parent rock would however also be limestone!
Limestone can metamorphose into marble, a regional metamorphic rock, or into skarn, a contact metamorphic rock.

Skarn forms from the alteration of carbonate rocks such as limestone or dolomite in the presence of hydrothermal fluids during contact metamorphism caused by intruding igneous rocks, typically granitic in composition. This process leads to the formation of a distinct mineral assemblage including garnet, pyroxene, and calc-silicate minerals.

The elements that move into fluid are higly souble in water. that are icompatible in carbnate rocks. The soluble elements settle around igneous rock form a skarn. Skarns can be ore bodies that incopatible elements like copper or gold.
Slate, gneiss, skarn, phyllite, hornfels, amphibolite, schist, quartzite, marble, and granulite are all metamorphic rocks.
