Most skarn ore is near the intrusion-sedimentary rock contact. Mineral characteristics Textures: Mineral grains are typically medium to coarse grained (0.5 to >1 cm), and range in texture from euhedral to massive interlocking grains. Trace element contents: In many deposits, sphalerite typically has very high iron contents (5-20 mol percent) and Sphalerite is one of the few minerals that can range from gemmy transparent crystals to dark, metallic -black crystals. An interesting variety of Sphalerite is known as Schalenblende. Schalenblende is banded variety associated with Wurtzite and often also Pyrite and Galena that forms strange concentric shapes.

Geological Survey Trace Element Investigations TEI-415, 119 p.Chalcopyrite is easily the most widespread copper-bearing mineral. A common mineral found in almost all sulfide deposits, chalcopyrite usually occurs in medium-temperature and high-temperature hydrothermal veins in igneous rocks or metamorphosed igneous rocks. Some economic chalcopyrite deposits form as hydrothermal fluids dissolve copper from ...

Sphalerite (Sphalerite). Sphalerite is a zinc sulfide mineral found not only all across the Earth, but also in lunar rocks and meteorites. It's the number one ore of zinc, but it's also a source of cadmium, germanium, gallium, and indium. The yellow, red, orange, and green crystal forms are prized in the gemstone market for their beautiful light dispersion properties, although the stone is too ...Aug 11, 2018 · The sphalerite chemical formula is ZnS (zinc sulfide.) This chemical formula represents sphalerite in its pure form, but it is much more commonly found with significant amount of other elements substituting zinc. Up to 26 % Fe, 17 % Cd, 15 % Hg, 21 % Mn and small amounts of Cu, In, Ga, Ge and As may replace the zinc.

Sulfides occur in all rock types. Except for dissemination in certain sedimentary rocks, these minerals tend to occur in isolated concentrations which make up mineral bodies such as veins and fracture fillings or which comprise replacements of preexisting rocks in the shape of blankets. Sulfide mineral deposits originate in two principal processes, both of …Purple fluorite cubes are intermixed with dark brown sphalerite crystals. This specimen is from Denton Mine, Cave-in-Rock, Hardin County, Illinois.Carbonate-hosted Pb–Zn deposits frequently contain significant amounts of critical metals such as germanium in sphalerite. However, the textural and chemical controls leading to Ge enrichment remain poorly constrained. Based on textural observations and laser-ablation (multi-collector) inductively coupled plasma mass …

A magmatic deposit is one in which the metal concentration takes place primarily at the same time as the formation and emplacement of the magma. Most of the nickel mined in Canada comes from magmatic deposits such as those in Sudbury (Ontario), Thompson (Manitoba) (Figure 20.4), and Voisey’s Bay (Labrador).
