(med) Chalcopyrite, Copper iron sulphide CuFeS2 (Yeshi 2018). Most abundant copper ore with brass yellow color ('catgold' in german), weathering may lead to the formation of malachite, azurite and numerous other secondary copper minerals (mindat.org).
(med) Marcasite, FeS2, golden stone, stone with golden specks (Drungtso 1999). Brass-yellow, metallic mineral ; tin-white on fresh exposures. The word is Arabic or Moorish and was applied to pyrite and similar metallic bronze colored minerals. Most frequently found in sedimentary rocks and coal beds, as a replacement mineral forming fossils, it is a mineral of low-temperature, near-surface, environments, forming from acid solutions. Pyrite (gser zil), the more stable form of FeS^2, forms under conditions of higher temperatures and lower acidity or alkaline environments. Several mining sites in Tibet (mindat.org).
