新疆加曼特金矿与阿希金矿的矿物学比较研究

Xinjiang Jiamante gold deposit is located in the parts of the Yili Asian plate of Boluo Huoluo Paleozoic island arc area Yelimodun metallogenic belt, West of it is the large Axi gold deposits in Tulasu metallogenic belt. Tulasu-Yelimodun volcanic belt is a long and narrow band extending in NEE direction, more than 100 kilometers long,,North and south more than 20 kilometers wide.This deposit is located in the ore belt (figure 1), it has a special geological location, and geological research is also of great significance. Starting with the geological characteristics of the deposit ,This paper tries to research the mineral assemblages and mineral standard type of Jiamante gold deposit,and especially focus on the fluid inclusions mineralogy characteristics. Using micro temperature measurement、stable isotope analysis and laser Raman microprobe ( LRM ) and other means, to reveal its metallogenic conditions and deposit genetic types, then systematically study its mineralogical characteristics and compared with the large Axi gold deposit which is west of it. Make clear the gold mineralization characteristics of Jiamante, offering some basis for the further widen prospecting new fields of this area.The project applicant sincerely wish for the strong support from the National Natural Science Foundation of China and the members of evaluation experts，and the results will have an important role in promoting the economic development of Xinjiang's ethnic minority areas.

新疆加曼特金矿在区域上位于伊犁亚板块的博罗霍洛古生代岛弧区也列莫顿成矿带，西邻为赋存阿希大型金矿床的吐拉苏成矿带，吐拉苏-也列莫顿矿带呈一狭长带北西西向展布，长100余公里，南北宽20余公里。该矿床位于其矿带中(见图1)，地质位置特殊，目前已成为北疆一个重要的成矿研究区域，受到国内外同行的极大关注，地质研究意义重大。本课题力图从加曼特金矿床的矿物学及地质特征入手，并与西邻的阿希大型金矿进行系统的矿物学对比研究，应用显微测温分析、稳定同位素分析及激光拉曼显微探针(LRM) 等手段，系统研究该矿床的矿物及矿物标型特征，矿物组合及流体包裹体矿物学特征等，并与阿希金矿对比研究，揭示其成矿条件，矿床成因类型，搞清加曼特金矿成矿规律及特点，为拓宽该区找矿新领域，提供重要依据。项目申请人恳切希望得到国家自然科学基金委和各位评审专家和的大力支持，其研究成果将会对新疆少数民族地区的经济发展有着重要推动作用。
