Exsolution of chalcopyrite from bornite-digenite solid solution: an example of a fluid-driven back-replacement reaction

Sulfide minerals host most of the world’s supplies of metals such as Cu, Ni, Co, Zn, Pb, or Mo, and understanding their crystallization, dissolution, and textural evolution is key to understanding the formation of mineral deposits, metal recovery via metallurgy, and their environmental impact. Despite the prominence of hydrothermally formed sulfide minerals, the interpretation of textures in sulfide petrology relies mainly on comparison with...
