TYPOMORPHIC FEATURES OF CHOVDAR GOLD DEPOSIT ORES, LESSER CAUCASUS (AZERBAIJAN)
Using the results of modern precision instrumental methods of minerals diagnosis including QEMSCAN <sup>TM</sup> operating mineralogical system a detailed analysis is given to the material composition (chemical and mineralogical) and the occurrence forms of metallic and non-metallic minerals in oxidized and fresh ores of Chovdar gold deposit. Sizes, chemical composition and structural relations of precious metals (Au, Ag) with different minerals of these ore types are given a quantitative assessment. Argentiferous minerals - jalpaite (Ag <sub>3</sub>CuS <sub>2</sub>) and stromeyerite (AgCuS)- that are very rare for this type of minerals are identified.
