摘  要：
1017高地银多金属矿床是武警黄金部队在内蒙古发现的一个多金属矿床,其大地构造位置处于华北板块与西伯利亚板块缝合带的北侧,区域构造复杂,成矿条件优越。东乌珠穆沁旗成矿带也是中国重要金多金属成矿带,区内以富含金、银、铅、锌和铁等中低温多金属矿床为主,其次为富含钼、钨、铬、铋、锡和稀有金属为主相对高温多金属矿床。通过对1017高地银多金属矿床岩石地球化学特征的研究分析,矿石石英中流体包裹体均一,测温为210.1℃,具有中低温度的特点;流体包裹体盐度在7.4%左右,为中低盐度;矿石中硫同位素总体组成相对均一;氢、氧同位素分析研究表明矿体流体不是典型的岩浆水与变质水,而是来源于岩浆与大气降水混合水;成矿时代为华力西晚期花岗质岩浆期后热液型银多金属矿床。矿床成因的确定对于区域找矿具重要的指导意义。

摘  要：
The Highland 1017 Ag polymetallic deposit is a polymetallic deposits discovered by Chinese People's Gold Armed Police Force in Inner Mongolia.Its tectonic position is located at the north side of suture zone between North China plate and Siberia plate,and the regional tectonic is complex and the metallogenic condition is superior.East Ujumqin Banner metallogenic belt is an important polymetallic metallogenic belt in china,the mainly deposit is middle-low temperature polymetallic deposit which is rich in gold,silver,lead-zinc and iron,following by the relatively high temperature polymetallic deposit which is rich in molybdenum,tungsten,chromium,bismuth,tin and rare metal.By studying the ore geochemical characteristics of the highland 1017 Ag polymetallic deposit,it is found that homogenization temperature and salinity of quartz fluid inclusion are 210.1℃ and 7.4%,respectively,with the characteristics of low temperature and low salinity.And the isotopic composition of sulfur is relatively uniform;hydrogen and oxygen isotope analysis shows that ore fluids are from the mixture of magma and rain water,not the typical magmatic water and metamorphic water.The deposit is the granitoid magmatic hydrothermal Ag polymetallic deposit which was formed in the late-Variscan.The determination of metallogenic genesis has guiding significance for regional prospecting.
