1. Skarn

   Skarns or tactites are hard, coarse-grained metamorphic rocks that form by a process called metasomatism. Skarns tend to be rich in calcium-magnesium-iron-manganese-aluminium silicate minerals, which are also referred to as calc-silicate minerals. These minerals form as a result of alteration which occurs when hydrothermal fluids interact with a protolith of either igneous or sedimentary origin. In many cases, skarns are associated with the intrusion of a granitic pluton found in and around faults or shear zones that intrude into a carbonate layer composed of either dolomite or limestone. Skarns can form by regional, or contact metamorphism and therefore form in relatively high temperature environments. The hydrothermal fluids associated with the metasomatic processes can originate from either magmatic, metamorphic, meteoric, marine, or even a mix of these. The resulting skarn may consist of a variety of different minerals which are highly dependent on both the original composition of the hydrothermal fluid and the original composition of the protolith.If a skarn has a respectable amount of ore mineralization that can be mined for a profit, it can be classified as a skarn deposit.

1. Skarn

   Skarn is an old Swedish mining term originally used to describe a type of silicate gangue, or waste rock, associated with iron-ore bearing sulfide deposits apparently replacing Palaeoproterozoic age limestones in Sweden's Persberg mining district. In modern usage the term "skarn" has been expanded to refer to calcium-bearing silicates of any age. In America the term "tactite" is often used synonymously with skarn. Skarns and tactites are most often formed at the contact zone between intrusions of granitic magma bodies into contact with carbonate sedimentary rocks such as limestone and dolostone. Hot waters derived from the granitic magma are rich in silica, iron, aluminium, and magnesium. These fluids mix in the contact zone, dissolve calcium-rich carbonate rocks, and convert the host carbonate rock to skarn deposits in a metamorphic process known as "metasomatism". The resulting metamorphic rock may consist of a very wide variety of mineral assemblages dependent largely on the original composition of the magmatic fluids and the purity of the carbonate sedimentary rocks. Skarns are sometimes associated with mineable accumulations of metallic ores of iron, copper, zinc, lead, gold, and several others. In such cases these deposits are called "skarn deposits".
