Ore Material Composition and Ore-Forming Stage Division of the Sandaozhuang Superlarge Molybdenum-Tungsten Ore Deposit in Luanchuan, Henan Province
Based on a discussion on the metallogenic geological setting, the authors studied the ore material composition. Mineral species and content vary remarkably in different types of ores. Division and comparison were made for mineral constituents of various ore types according to their components and formation stages. The major useful components seem to be Mo and W. In addition, S and Re can be retrieved for comprehensive utilization. The modes of occurrence of various elements were also analyzed. According to mineralization characteristics, mineral association and formation sequence, the ore-forming process can be divided into three phases composed of six stages. The results obtained are of reference and guiding significance in searching for similar ore deposits.
