摘　　要：从矿床成矿地质背景和矿床基本特征入手,探讨了它温查汉西铁多金属矿形成的基本条件和找矿前景,并指出了进一步找矿的方向。它温查汉西铁多金属矿矿床是一处隐伏于广厚覆盖层下的矽卡岩型矿床,位于柴南缘祁漫塔格成矿带,华力西期的酸性侵入岩和滩间山群(OST)碳酸盐岩接触带形成典型的矽卡岩型铁铜锌金等工业矿体。发现该矿主要是根据1∶1万高磁测量圈定的11处异常,今后找矿思路应逐步由磁异常导向找矿向地质规律和异常结合找矿的方向改变,并总结成矿规律和异常-矿体空间分布规律,不断探索和使用新方法。认为C5异常东段、C11异常正负异常伴随处、C6异常、C8异常南侧东西两端相对游离于大面积异常的地段都是找矿的有利地段。The based on the ore-forming geological background and characteristics of the Tawenchahan de- posite , its metallogenic condition and prospecting are inquired into and its prospecting criteria are summa- rized. Tawenchahan polymetallic ore mineral deposits is a thick coating lurks in the wide under the skarn deposit, located on the south edge of the wood-forming zone Qimantag, ore-controlling factors is the acid- ity of the Variscan Hills between intrusive rocks and the beach （OST） carbonate rocks, forming a typical contact zone between the two skarn iron ore copper zinc gold and other industries. Its findings are mainly based on 1/10 000 high magnetic measurements delineated 11 anomalies in the future prospecting ideas should be gradually driven by the magnetic anomalies to geological prospecting and unusual combination of law to change the direction of exploration and summary of the law and abnormal mineralization - spatial distribution of ore bodies, and constantly explore new methods. That abnormal eastern C5, Cll positive and negative anomalies associated with abnormal location, C6 abnormal, C8 is relatively separated from the abnormal south east and west ends of the lots are large areas of abnormal direction of exoloration.
