Exempel på hur man kan använda SKARNS i en mening

• Coarsely crystalline apatite is usually restricted to pegmatites, gneiss derived from sediments rich in carbonate minerals, skarns, or marble.
• The wolframite series is mainly formed through magmatic-hydrothermal processes associated with felsic magmas, namely skarns, or through metamorphic processes.
• Gold production came from underground lode mines exploiting: gold-bearing quartz veins in metamorphic rocks (such as the Gold Standard, Sea Level, Dawson, Golden Fleece and Goldstream mines); skarns (at the Jumbo and Kassan Peninsula copper-gold mines); zoned mafic-ultramafic plutons, as at the Salt Chuck silver-gold-copper-PGE mine; and VMS deposits such as Niblack.
• Diopside is also found in a variety of metamorphic rocks, such as in contact metamorphosed skarns developed from high silica dolomites.
• thumb In the igneous environment, metasomatism produces skarns, greisen, and may affect hornfels in the contact metamorphic aureole adjacent to an intrusive rock mass.
• It occurs in skarns developed in contact metamorphosed impure limestones or calcic igneous rocks; in chlorite schists and serpentinites and in alkalic igneous rocks (typically titaniferous).
• Other occurrences include Falun, Sweden where it is found in pegmatites and skarns; and, in the United States, Charlemont, Massachusetts; Spruce Pine, North Carolina; White Picacho district, Arizona; Topsham, Maine; and Franklin, New Jersey.
• occurs naturally as the mineral eskolaite, which is found in chromium-rich tremolite skarns, metaquartzites, and chlorite veins.
• The gold is found in four distinct configurations: disseminated throughout the mineralized sediments; as silica replacement; in breccias having magno-calcite quartz veining; and occasionally as porphyritic skarns.
• Perovskite is found in contact carbonate skarns at Magnet Cove, Arkansas, US, in altered blocks of limestone ejected from Mount Vesuvius, in chlorite and talc schist in the Urals and Switzerland, and as an accessory mineral in alkaline and mafic igneous rocks, nepheline syenite, melilitite, kimberlites and rare carbonatites.
• It occurs in chromium bearing tremolite skarns, metamorphosed quartzites and chlorite bearing veins in Finland; in glacial boulder clays in Ireland and in stream pebbles in the Merume River of Guyana.
• They noticed secondary minerals forming between szaibelyite and ludwigite at the point where they come into contact with each other inside magnetite skarns.
• Within them, non-ferrous metal skarns occur - some forming gravel deposits and bearing pyrites - as well as lodes of a bismuth-cobalt-nickel-silver formation.
• Mineral associations include carbonate minerals, zinc-bearing chromite, rutile, uraninite, nolanite, graphite, zircon, titanite, and corundum as well as in chromium-rich tremolite skarns, metaquartzites, and chlorite veins.
