The mineral resource is an important material basement for national economic and socialdevelopment. In recent years with the quickly speeding up to the industrialization, urbanizationand agricultural modernization in China, the imbalance between supply and demand for themineral resource in China has been more increasingly existed. As the result of the internationalmineral market competition becoming more intensely and sharp, and more difficult fordepending on the international market, it is a significant and strategic policy for our economicand social development to accelerate mineral exploration and assure enhancing domestic mineralcapacity.Hadayinari Tin-polymetallic Deposit,located in the Xiwuqi-Huolinguole lead-zincmetallic mineral perspective area in Inner Mongolia, recently a new-found and significanthydrothermal filling and metasomatic deposit for lead-zinc-tin-copper mineralization, occurredin the Great Khingan metallogenic belt. On the basis of comprehensively comparing andanalyzing the regional geology through this article, more deep research work upon the geologic,geochemical and geophysical features of the deposit has been taken, further the potential mineralresources has been evaluated relevantly, especially it is worthy and more important guide forfinding the new similar deposits in the adjacent area.The main achievements and conclusions listed below in this article,a. The metallogenic geologic conditions and control factors relative in the deposit aredefined preliminarily, and ore-bearing anomaly explained, as well as the orebodiesdelineated.The control factors of the mineralization are summed up initially, and indicators forprospecting new deposits are set up.b. Through the check of the key geochemical anomalies in the deposit, it makes sure thatthe anomalies are occurred in the fault zone mostly. Meantime it is shown that IP anomalies arepresent and the strike of them is parallel to the direction of the tectonic structure, lie in theconnect areas between the volcanic edifice and upfold belt in the basement by geophysicalfeatures, a good potential for seeking mineralization is existed;c. The main types of wall rock alteration are described around the orebody, it is believedthat close relationship between and mineralization and wall rock alteration is clear. Therefore bythe study of the distribution and occurrence of the orebody synthetically, the genetic type of thedeposit is defined as the hydrothermal filling and metasomatic deposit. d. The initial mineralized evaluation of the Hadayinari Tin-polymetallic Deposit expandsthe shape,scale,occurrence,and grade of the orebodies, in addition the composition and qualityof the ore also has been known.
