  • 摘 要:布丘克金矿床的成矿理论研究较为薄弱,矿床成因上没有形成统一的认识,为丰富成矿理论,指导找矿工作,从地质时空背景的角度出发,对矿床成因提出了新的认识。研究表明,加里东运动期间帖尔斯克伊洋的关闭,尼古拉耶夫—那拉提山北缘断裂带的形成是布丘克金矿床基本的成矿动力背景,此间形成的阿克塔什揉皱带是主要的控矿构造,岩体与特定的结晶凝灰岩、凝灰质砂岩发生交代作用,产生了物质交换,使金元素富集成矿。综合已有探矿资料和找矿实践,可以判定,布丘克矿段、阿克塔什矿段深部具有良好的找矿前景,应综合多种勘探手段进行地质探矿。

    Geologicalconditions and prospecting perspectives of Buchuk Gold Deposit in theKyrgyzstan……Yang ShuaiYeernaer BielikeLi YuyangZhang Shun

    AbstractThe ore-forming theory of the Buchuk Gold Deposit issoundly studied and the genesis of the deposits is controversial.In order toadvance the ore-forming theory of the Buchuk Gold Deposit and guide theprospecting work,the paper comes up with new understanding of the depositgenesis from the perspective of geological time-and-space settings.The resultsshow that the closure of the Terskey ocean during the Caledonian movement andthe formation of the northern rim fault of the Nikolaev-Nalati Mountains arethe basic metallogenic power background of the Buchuk Deposit.The Aktashicrumpled belt formed in this period is the main ore-controlling structure.Afterthe metamorphism of the rock mass with the concrete tuff and tuffaceoussandstone,material exchange happened so that the gold element is enriched tomineralization.Based on comprehensive analysis of existing prospecting data andpractice,it can be concluded that deep in Buchuk ore section,Aktashi oresection,there are good prospecting potentials which should be explored by avariety of means.
