    摘要:

    马家疃金矿区位于胶东著名的台前陡崖金成矿带上盘,笏山、西陡崖金矿床东邻。笏山、西陡崖矿区已累计提交金资源储量30余吨,其主矿体倾向深部,向马家疃矿区延伸稳定。区内地层出露单一,岩浆岩发育,矿体产出于玲珑花岗岩体中,严格受NNE向压扭性断裂控制,矿石类型主要为黄铁绢英岩化碎裂岩。通过对矿床地质特征及矿床成因的分析,其深部有较大的找矿前景,在总结成矿规律的基础上,围绕有利构造部位进一步勘查,有望实现栖霞地区找矿的再次突破。

    Abstract:

    Majiatuan gold area is located in the upper part of TaiqianDouya gold mineralization belt in Jiaodong area, and east part of Hushan and Douya gold deposits. 30 tons gold reserves have been submitted accumulately. Its main tendency of deep orebody extented to Majiatuan mine. Strata in this area overcropped simply, magmatic rocks developed well, ore bodies occurred in Linglong granite and are strictly controlled by compressoshear faults with the trend of NNE, and ore types are mainly beresitization cataclastic rocks. Through analysis on geological characteristics and the origin of the deposit, it is regarded that there is a great prospect for prospecting in its deep part. On the basis of summarizing etallogenic regularity and further exploration of favorable structures, breakthrough of ore prospecting can be realized in Qixia area.
