The Dynamic Mechanisms for the Formation of Primary Metal Zoning of Cassiterite‐Sulfide Deposits in the Gejiu Metallogenic Province, Yunnan

The Dynamic Mechanisms for the Formation of Primary Metal Zoning of Cassiterite‐Sulfide Deposits... Abstract Copper and tin in cassiterite‐sulfide deposits of the Gejiu metallogenic province are intimately associated and show peculiar primary metal zoning. The authors made use of computer techniques to simulate numerically the zoning of these ore deposits. The study shows that the regular spatial zoning probably resulted from the succession of multiple, intermittent and pulsatory mineralizations. The successive transports with diverse velocities along channelways of the ore‐forming solutions, taking place under conditions of definite difference between metal concentrations, in solutions and wallrocks, followed by differential deposition, constitute possible dynamic mechanisms for the primary metal zoning. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Geologica Sinica (English Edition) Wiley

Abstract

Abstract Copper and tin in cassiterite‐sulfide deposits of the Gejiu metallogenic province are intimately associated and show peculiar primary metal zoning. The authors made use of computer techniques to simulate numerically the zoning of these ore deposits. The study shows that the regular spatial zoning probably resulted from the succession of multiple, intermittent and pulsatory mineralizations. The successive transports with diverse velocities along channelways of the ore‐forming solutions, taking place under conditions of definite difference between metal concentrations, in solutions and wallrocks, followed by differential deposition, constitute possible dynamic mechanisms for the primary metal zoning.
