[研究目的]赤瓦屋铜钼矿位于太行山北段成矿带,属于找矿突破战略的重点勘查区域,目前找矿工作进入瓶颈期,本研究对下一步找矿突破具有重要指导意义.[研究方法]本文基于对赋矿岩体、矿床地质特征、地球物理、地球化学和遥感地质的综合研究,分析找矿标志.[研究结果]认为赤瓦屋铜钼矿与深部花岗斑岩有关,具有斑岩型矿床的典型矿化特征,形成于早白垩世;研究区环形构造发育,大型环形构造与赤瓦屋岩体及外围隐伏岩体有关,小微型环形构造多数与隐蔽爆破角砾岩或隐伏小岩株有关;地球化学异常及遥感蚀变异常的空间分布吻合程度高,对矿化具有显著的控制作用;提出了 4个找矿靶区.[结论]在赤瓦屋岩体内部应把确定隐爆角砾岩体和隐伏花岗斑岩体的空间位置作为找矿工作的重点,以寻找Cu、Mo矿为主;外围应以Cu、Au、Ag多金属矿为主.
Characteristics of the Chiwawu Cu-Mo deposit in the northern section of Taihang Mountains and the prediction of prospecting target area using geological,geophysical,geochemical and remote integrated information
This paper is the result of mineral exploration engineering.[Objective]The Chiwawu copper-molybdenum deposit is located in the northern Taihang Mountains metallogenic belt,which is one of the key exploration zones as part of the'Prospecting Breakthrough Strategy'implementation.However,the mineral exploration in this deposit has entered a bottleneck stage currently.This study aims to provide new target areas for the deposit.[Methods]Identify exploration indicators based on a comprehensive interpretation of the geological,geophysical,geochemical,and remote sensing data of the deposit.[Results]The deposit was formed in the Early Cretaceous and exhibits similar mineralization characteristics to typical porphyry deposits,indicating a close association with deep-seated granite porphyry.Circular structures are widely distributed in the study area,with large circular structures associated with the Chiwawu coplex and other concealed intrusions,while small to macro-sized circular structures are associated with cryptoexplosive breccias or concealed small stocks.There is a strong spatial correlation between the geochemical anomalies and alteration zones discriminated using the remote sensing data,which can serve as an effective indicator for mineralization.Four exploration target areas are delineated.[Conclusions]Within the Chiwawu complex,locating the cryptoexplosive breccias and concealed granite porphyry is crucial for Cu and Mo prospecting,while in the surrounding area prospecting,the focus is recommended to be on Cu,Au,and Ag.
