中文摘要:
      通过哈西亚图多金属矿床地物化及矿产特征及成因类型研究,总结了系列找矿标志,并利用找矿标志进行了找矿预测。研究认为:哈西亚图多金属矿床产有铁、铅、锌、金等多种矿种,赋矿部位主要为长城系小庙组与华力西期侵入岩接触部位形成的矽卡岩中;矿区中心部位圈定出的1∶5万地磁异常峰值高(-72~2305 nT),采用衬值法圈定出1处1∶5万甲1类水系沉积物综合异常;矽卡岩化、透辉石化等围岩蚀变发育;矿床成因类型为层状矽卡岩型;中灶火上游地区具有形成类似哈西亚图多金属矿床的潜力。
英文摘要:
      Based on the study of mineralization and mineral characteristics and genetic types of the polymetallic deposits in Haxiyatu region, a series of prospecting marks, were summarized and the prospecting prediction was carried out by using these prospecting marks in this paper. The research indicates that:Haxiyatu polymetallic deposit includes aboundant of minerals such as iron, lead, zinc and gold. The mineralization exists in the skarn of the contact area between Variscan intrusive rocks and the stratum of Xiaomiao Group of Great Wall period. The peak value(-72~2305 nT)of 1∶50,0 geomagnetic anomalies was determined in the central part of the mining area. Using the contrast method, the synthesis anomaly of 1∶ 50,0 A-1 type of water system sediments was determined. In where, the lithologies of skarn, diabase and other surrounding rocks are developed. The genetic type of the deposit is stratified skarn. It is predicted that the upstream of Zhongzaohuo area has potential to form similar polymetallic deposit to Haxiyatu.
