河南北架山钼(金)矿床地质特征及找矿前景
|
摘要
北架山钼(金)矿床位于华北陆块南缘的豫西成矿带上。通过对该矿床的成矿地质背景、控矿因素分析,认为该矿床属于构造蚀变岩型钼(金)矿,这是在该区新发现的又一钼金矿床。详述了该矿床的地质特征、物化探异常特征、找矿标志,进而提出了新的找矿前景。
The Beijiashan molybdenum(gold) deposit is located in the western Henan metallogenic belt on the southern margin of the North China block. Through detailed analysis of the geological characteristics of the deposit and the geophysical and geochemical anomaly characteristics, the secondary fault structure-NE fault fracture zone in the mining area provides a sedimentary site for oreforming material deposition and enrichment, which is an important ore-bearing structure of the mining area. The Yanshanian second mica granite intrusion is beneficial to mineralization, and the type of deposit belongs to the tectonic altered rock type molybdenum(gold) ore. The east-west fault zone has obvious control effects on the deposit, and the geophysical exploration and geochemical exploration show abnormalities are important prospecting indicators. This is another newly discovered molybdenum gold deposit in the area with new prospecting prospects.
