2.The formation of auriferous stratawas controlled by volcanism and eustacy.
火山作用和海平面变化对含金层的形成起到了控制作用。
3.4—韧性变形带及含金黄铁绢云岩带;
4—Ductile deformation zone and auriferous beresitization zone;
4.(4) ore bodies occurring as lenses with the auriferous laminar assemblages conformable with the mylonitic foliation;
③含金纹带状集合体组成主为细粒石英和黄铁矿;
5.In the northwest of China, auriferous altered cataclasite, adular-sericite quartz vein and quartz reef types are present, and metallogenetic epoch is mainly Hercynian period.
西北部区主有变碎裂岩型、冰长石-绢云母石英脉型和石英脉型等,成矿时代主为海西期;
6.The gold metallogeny is characterized by auriferous pyrite and occurred in the alternating layer of heavy-layer metasandstone,flaggy metasandstone and graphitization schist.
