摘要
为研究东昆仑东段龙什更地区铜、钴多金属及石墨矿的成矿规律,采用了地球化学异常特征分析、地球物理异常特征分析以及高精度磁法测量和激电剖面测量等方法,对研究区的成矿地质、含矿地质体和控矿因素进行了深入分析。结果显示,该区域存在多种成矿类型,包括热水沉积型铁钴矿、构造蚀变岩型银铜铅锌矿和区域变质型石墨矿。研究发现,铁、钴矿产主要赋存于万保沟群灰岩与千枚岩接触带中,银、铜、铅锌矿产于含矿构造带中,而石墨矿赋存于金水口群片麻岩中。研究区的成矿条件受地层、构造、岩浆活动等多重因素控制,成矿类型多样,为后续矿产勘查提供了明确的找矿标志和方向。
To study the ore-forming laws of copper-cobalt polymetallic and graphite deposits in the Longshigeng area of the Eastern Kunlun Mountains,methods such as geochemical anomaly feature analysis,geophysical anomaly feature analysis,high-precision magnetic measurements,and induced polarization profile measurements were used to conduct in-depth analysis of the mineralization geology,ore-bearing geological bodies,and ore controlling factors in the study area.The results indicate that there are multiple types of mineralization in the region,including hydrothermal sedimentary iron-cobalt deposits,tectonic altered rock type silver-copper-lead-zinc deposits,and regional metamorphic graphite deposits.Research found that iron-cobalt minerals mainly occur in the contact zone between the Wanbaogou Group limestone and phyllite,silver-copper-lead-zinc minerals in the ore-bearing structural zone,and graphite minerals in the Jinshuikou Group gneisses.The mineralization conditions in the research area are controlled by multiple factors such as stratigraphy,structure,and magmatic activities,and the types of mineralization are diverse,providing clear prospecting indicators and directions for subsequent mineral exploration.
