摘要
二道甸子金矿床的地质特征是:(1)矿体形态受断裂构造和云母石英角岩及斜长角闪角岩互层带两者的控制;(2)后生含金石英脉与同生层纹状硫化物相伴产出;(3)存在中温和低温的两个矿化阶段;(4)包体研究表明具有某些层控热液和岩浆热液矿床的特征,因此,该矿床是属于复成岩浆热液矿床.
The geological characters of Er-dao-Dian-Zi Gold Deposits are as follows:
1) The forms of the ore body is under the control both fault strutures and in-terbedding horizons of biotite-quartz hornberg and plagioclase-hornblende hornberg.
2) Deuterogenic auriferous quartz-veins and contemporagenic lamellar sulfides associatively occur. 3) There are two mineralization stages of meso and low-temperature. 4) Compositions of the fluid inclusion displayed some features of strabound or magmatic hydrothermal deposits. Therefore, this deposits belongs to polygenetic magma-hydrothermal one.
