Are there any mines in the Dominican Republic?

  • Mining & Geology in the Dominican Republic. The history of the Dominican Republic has deep running roots based on the gold and mining industry. Today there is a growing mining and exploration community made up of many explorers and three major mining companies. Barrick, with a 60/40% partnership with Goldcorp, operates the Pueblo Viejo gold mine.

Clinohumite is an uncommon member of the humite group, a magnesium silicate according to the chemical formula (Mg, Fe) 9 (Si O 4) 4 (F,OH) 2.The formula can be thought of as four olivine (Mg 2 SiO 4), plus one brucite (Mg(OH) 2).Indeed, the mineral is essentially a hydrated olivine and occurs in altered ultramafic rocks and carbonatites.Most commonly found as tiny indistinct grains, large ...

"Clinohumites are one of the fiercest and fieriest gems I know. Their ability to terraform magma and transport superheated rocks and stones makes them exceptionally useful when developing colonies. Their strength is undeniable, that's for sure. It's neat seeing how quickly they can transform the surface of an organic planet and rebuild it into something entirely new!" - In game description 1 ...

The assemblage titanian clinohumite+forsterite +spinel+calcite is widespread in marbles from the eastern Bergell contact aureole (Switzerland/Italy). The Bergell titanian clinohumites vary considerably in composition (TiO 2 : 0.19 to 2.05 wt%, F: 2.2 to 3.4 wt%). Electron microprobe analyses show that the titanian clinohumites contain less than detectable amounts of Co, Cu, Ni, Zn, Al, Cr and Cl.

Marble lenses within the polymetamorphic Ötztal crystalline complex frequently contain pockets of clinohumite and chondrodite and their titanium-rich varieties. Chondrodites contain up to 9.1 wt% TiO2 and clinohumites about half that amount. The maximum amounts of Ti in both minerals do not exeed values of 0.4 in the formula. XTi and XF are correlated by a slope of −1, indicating the ...

Abstract. Single crystals of the humite-group minerals, with general crystal chemical formula n·[M2SiO4]·[M1-xTix(F,OH)2-2xO2x] where M is predominantly Mg eventually substituted by Fe2+, are studied by electron microprobe analysis, X-ray diffraction and polarised electronic absorption spectroscopy, in the present paper two chondrodites (n = 2) and four clinohumites (n = 4).

They’re grown from the same chemical ingredients and under the same physical conditions as mined gems, except at a greatly accelerated rate. Lab-created gems aren’t fakes. For example, lab-created rubies are real rubies, but they’re not natural rubies. (They’re also far less expensive than their mined counterparts).
