摘要
近十年来,它温查汉西矿区经过连续勘查,在铁铜锌金多金属找矿中不断取得新进展,全区共圈定矿体91条,具有很好的找矿前景。笔者通过对它温查汉西矿区地质特征、矿床控制程度、矿床特征、矿石矿物特征等进行分析研究,运用区域成矿理论,总结本区铁铜锌金多金属矿的成矿规律。研究认为,本区C5、C11、C10异常主要为矽卡岩型矿床,矿种为铁铜锌金;C6异常主要为热液型矿床,矿种以铜金为主;C8异常出现的大片的低缓异常和高温钼元素,要考虑深部斑岩体的存在。结合矿区已有的成矿事实,建立了以斑岩型矿床(C8异常)-热液型矿床(C6异常)-矽卡岩型矿床(C5、C10、C11异常)为主的找矿模型。
Over the past decade,the west Tawenchahan mining area has continuously made new progress in the exploration of iron,copper,zinc,and gold polymetallic deposits,a total of 91 ore bodies have been delineated,with a very good prospect for mineral exploration.This article analyzes and studies the geological characteristics,ore body control degree,ore body characteristics,and ore mineral characteristics of the West of Tawenchahan mining area.By applying regional metallogenic theory,it summarizes the ore-forming regularities of iron,copper,zinc,and gold polymetallic deposits in this area.It is believed that the anomalies C5,C11,and C10 are primarily associated with skarn-type ore deposits,with iron,copper,zinc,and gold as the main minerals.Anomaly C6 is mainly associated with hydrothermal ore deposits,with a focus on copper and gold.The extensive low-amplitude anomaly and high-temperature molybdenum element associated with anomaly C8 suggest the presence of deep-seated granitic intrusions.Combining the existing ore-forming facts in the mining area,a mineral exploration model is established,with a focus on C8 anomaly-related granitic-type ore deposits,C6 anomaly-related hydrothermal ore deposits,and C5,C10,C11 anomaly-related skarn-type ore deposits.
