山东五莲七宝山地区多金属矿体三维模型预测与评价

Three Dimensional Model Prediction and Evaluation of Polymetallic Ore Bodies in Qibaoshan Area in Wulian County in Shandong Province

摘要:

通过开展七宝山多金属矿杏山峪矿段、红石岗矿段和敞沟矿段深部成矿预测，定量分析与解释矿体的形成，建立了三维地质模型。依据模型预测了成矿靶区，经钻探验证，在窑头隐爆角砾岩筒，新发现7层铜及多金属矿体，成矿潜力和前景较好。研究表明，三维模型预测对矿区找矿具有较强的指导意义。

Abstract:

Through carrying out metallogenic predication, quantitatively analysis and explanation of the formation of ore bodies in Xingshanyu section, Hongshigang section and Changgou section of Qibaoshan polymetallic deposit, a three dimensional geological model of Qibaoshan polymetallic deposit has been established, and metallogenic target area has been predicated. Through drilling verification, 7 layers of copper polymetallic ore bodies have been found in Yaotou hidden cryptoexplosive breccia rock pipe. The mineralization potential and perspective in the deep are good. It is showed that three dimensional model prediction has strong guiding significance for prospecting in the mining area.
