山东省邹平火山岩盆地北西部覆盖区找矿潜力分析

Analysis on Prospecting Potentiality in Northwestern Zouping Volcanic Basin

摘要:

为了合理有效地勘查开发邹平火山岩盆地的铜矿资源，从2004年开始，在该区开展了地质调查工作，在北部第四系覆盖区重点部署了物探调查工作。从基本特征、成矿地质条件、地球物理场等方面，与地质特征相似的已知矿床进行类比、预测，认为邹平火山岩盆地北西部第四系覆盖区地球物理异常具有磁异常低、电阻率低、极化率高、重力场低的特征。并圈定出异常叠合区，认为该区找矿潜力大，成矿远景良好，目标矿种为铜矿及多金属矿。

Abstract:

In order to explore and use copper resource reasonably and effectively in Zouping volcanic basin, geological survey work has been carried out since 2004 in this aea. Geophysical survey has been carried out in Quaternary cover areas in the northern part. From the aspects of basic characteristics, geological conditions and geophysical fields, analogy and predication have been carrid out among already known deposits with the similar geological characteristics. It is regarded that there are geophysical anomalies with low magnetic anomaly, low resistivity, polarization rate, low gravity field characteristics in Zouping volcanic basin in northwestern area, and abnormal superposition areas have been circled. It is regarded this area has good prospecting and metallogenic potentiality. Its target minerals are copper and polymetallic ore.
