内蒙古自治区翁牛特旗大座子山银多金属矿地质特征及找矿前景浅析

Analysis on geological characteristics and prospecting potential of the Inner Mongolia Autonomous Region W engniute Dazuozishan silver polymetallic ore

勘查区矿体多产于断裂构造带中,严格受断裂构造带控制,矿体呈脉状产出,其产状与断裂(蚀变破碎带)产状一致,矿体规模、矿化强度与断裂(带)规模相关—断裂带规模越大,其包含的矿体数量越多,单个矿体规模相对较大,而且矿化强度也相对较强,矿石品位较高,反之亦然。据此推断该矿床成因为构造控制矿的火山热液脉型矿床。

The exploration area of ore bodies distribute in the fault zone,strictly controlled by tectonic belt,ore veinlike,t he occurrence of fracture(altered fracture zone)occurrence,ore scale,mineralization intensity and fracture scale(band)-rela ted fault zone size is larger,the more the number of packages containing ore the single ore scale is relatively large,and the mi neralization intensity is also relatively strong,high ore grade,and vice versa.It is concluded that the deposit is a volcanic hydr othermal vein type deposit with the structure controlled ore.
