GEOCHEMICAL AND THERMODYNAMIC MODELS FOR THE GENESIS OF LOW- AND MEDIUM-TEMPERATURE VEIN MINERALIZATION AND METASOMATISM IN THE WALL ROCKS

Abstract

The paper presents a systematic analysis of the genetic conditions and principal features of zoning in orebodies and related wall-rock aureoles at low- and medium-temperature vein hydrothermal deposits from the standpoint of the thermodynamic simulation of mineralizing processes. The author employs the equilibrium-dynamic approach, in which any process is visualized as a succession of equilibrium states with certain dynamical elements. Generalized models are developed for ore-forming hydrothermal systems at base-metal and uranium deposits, including the regions in which the primary mineralizing solutions are formed and those of ore deposition and the development of aureoles. The monograph is addressed to geologists dealing with mineral deposits and geochemists and can be utilized as a guide to simulating mineralizing processes for students and postgraduates.
