auriferous arsenopyrite

含金砷黄铁

The formation of auriferous stratawas controlled by volcanism and eustacy.

火山作用和海平面变化对含金层形成起到了控制作用。

4—韧性变形带及含金黄铁绢云岩带；

4—Ductile deformation zone and auriferous beresitization zone;

(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要为细粒石英和黄铁；

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.

西部区主要有蚀变碎裂岩型、冰长石-绢云母石英脉型和石英脉型等，成时代主要为海西期；

The gold metallogeny is characterized by auriferous pyrite and occurred in the alternating layer of heavy-layer metasandstone,flaggy metasandstone and graphitization schist.

金化以含金黄铁为特征,产出于盖县组变质砂岩段厚层状变质砂岩、薄层状变质砂岩和石墨化片岩互层带中,体产状与层一致;
