摘要
蚀变矿物-钠长石、含镁方解石、绢云母与自然金属同一成矿阶段的产物.钠长石、含镁方解石、自然金具有成分环带,在成矿过程中,局部成矿物理化学环境的改变是造成其成分环带的主要因素之一.
The native gold is the main gold-bearing mineral in the area studied. The relative purity of the gold is rather high, 977.6 in average. The gold and altered minerals-sericite, albite and Mg-calcite were formed in the same mineralization stage, which exhibit corresponding composition zones. The authors believe that the variation of local physico-chemical conditions of the hydrothermal fluids be one of the major factors resulting in such zoning.
