Abstract: The based on the ore-forming geological background and characteristics of the Tawenchahan deposite,its metallogenic condition and prospecting are inquired into and its prospecting criteria are summarized.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 acidity 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,C11 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 exploration.
