The types of mineralization Diaoyutai pyrite deposit��Jinxiantou Au- - Cu deposit and Qibaoshan Pb- - Zn deposit�� are homo- layered disseminated��cryptoexplosion breccia��and cleft- control hydrothermal pulse in type�� respectively�� The pyrites are the most developed metal sulfides in this area�� Based on the study of the occurrence�� crystal morphology and the diagrams of n S /n Fe (n S /n Fe =1. 985 ��2. 066)��δFe/δS (δFe/δS = ±5%)��δFe/δS �� As��(Fe + S) �� As��Co/Ni diagram��Co �� Ni �� As (Co/Ni =1. 2 ��11; Co/Ni =2 ��27; 0. 7 ��18) and correla- tion index of the trace elements�� Se �� Sb (0. 528)��Se �� Zn (0. 371)��Zn �� Sb (0. 642)��Pb �� Te (0. 463)�� �� etc�� We conclude that the magmatic hydrothermal influences the three deposits��the metallogenic materials are closely related to the magmatism�� The three kinds of pyrite are middle- temperature hydrothermal deposits which are related to the secondary volcanic complex of Qibaoshan��
