大地构造相方法在铜矿预测中的应用——以山东五莲—诸城地区为例

Application of Tectonic Phase Method in Predication of Copper Deposit—Setting WulianZhucheng Area in Shandong Province as an Example

摘要:

随着全国大地构造相划分方案日渐成熟，如何运用大地构造相方法找矿成为近几年的新课题。对此该文提出一种新的找矿思路：以已知矿产地的大地构造相（亚相）特征作为前提条件，结合已知矿产地地质、物化探找矿标志，在覆盖区圈定根据物化探特征推断出存在与已知矿产地具有相同或相似的岩石构造组合的地区，即为成矿预测区。该文以五莲—诸城地区为例，以五莲县七宝山铜矿作为已知矿产地，应用上述找矿思路，在诸城市瓦店镇附近圈定了铜矿预测区，该方法对其他矿种预测也有借鉴意义。

Abstract:

Accompanying with the perfection of dividsion program of tectonic phase in China, how to use tectonic phase method to search mines has become a new issue in recent years. In this paper, a new way for ore exploration has been put forward as follows: regarding characteristics of tectonic phase (subfacies) of already known deposits as the premise, using geological and geophysical and geochemical signs of known deposits, areas which have the same or similar rock structure combinations as known deposits have been circled out according to geophysical and geochemical characteristics in coverage areas. In this paper, setting WulianZhucheng region as an example, regarding Qibaoshan copper in Wulian county as a known deposit, by using the abovementioned exploration method, the copper prediction area nearby Wadian town of Zhucheng city has been circled out. This method can provide some references for the predication of other mineral resources.
