| 摘 要： | 山东省招远市西北部原疃地区地理位置特殊,位于区域上两大断裂金矿带之间的玲珑复式岩体的核部,与西北部的郭家岭花岗闪长岩疑似为断层接触关系,金矿成矿条件优越。运用激电中梯、高精度磁法测量,基本查明了区内与金成矿有关的岩体、断裂构造的分布情况,圈定激电异常7处,其中1处异常经验证为矿致异常。应用CSAMT,SIP方法对矿带的深部进行探测,确定其沿走向及倾向均有一定延伸,对其深部异常进行钻探验证,证明深部异常仍为矿致异常。综合找矿方法在此次找矿过程中发现了矿致异常,缩小了找矿靶区,为钻探工程的部署提供了依据。

| Abstract: | Yuantuan erea is in the northwest of Zhaoyuan city in Shandong province. Its geographical location is very special. Itis located in the core part of Linglong composite rock between two gold fracture belts. It has a suspected fault contact relationship with GuoJialing granodiorite in the northwest part. Metallogenic conditions of gold deposit is good. By using intermediate gradient survey and highaccuracy magnetic survey, the distribution of rock body and the fracture structures related to gold mineralization have been identified. Seven IP anomalies have been circled. Among them, one anomaly has been verified as mineralization anomaly. By using CSAMT and SIP methods, deep situation of the deposit has been detected. It is confirmed that there is a certain extent along the strike and tendency. Through drilling test, it is verified that deep abnormal is mineral anomaly. By using comprehensive prospecting methods, mineral abnormalities can be found, prospecting target areas in the process of prospecting can be found. It will provide a basis for drilling and engineering arrangement. |
