摘要
Pyrite is an ordinary mineral which appears in different types of deposits and it is an important gold-bearing mineral in gold deposits.Through studying the compositional typomorphic characteristics of pyrite,we have achieved much genesis information.This paper studied major and trace elements of pyrite of Jiaodong gold deposits by using δFe-δS,δFe/δS-As and(Fe+S)-As systems and achieved major elements characteristics of Jiaodong gold deposits.The results show that quartz-vein type,altered-rock type and interlayer slippage type of gold deposits in Jiaodong all have its typical characteristics for each distinct ore-forming environment.The result achieved in this paper proves that the compositional typomorphic method of pyrite is well applicable to each sub-type of gold deposits in Jiaodong,and is helpful for studying pyrite compositional typomorphism and for prospecting gold deposits.
