中文摘要:
      湖南省汝城县秀才洞地区在近几年的铀矿勘查工作中已发展为近中型规模铀矿床。为寻找隐伏矿体,进一步扩大矿床规模,作者在矿床范围内开展了构造原生晕垂向分带研究工作。研究认为,秀才洞地区成矿构造内成矿及指示元素的迁移富集趋势明显；铀成矿热液流体活动可划分为铀—红色玉髓—赤铁矿化、铀—灰色微晶石英—黄铁矿化、铀—萤石三个成矿阶段,不同期次、不同阶段的成矿流体带来的物质组成基本一致,后期成矿作用叠加在前期成矿作用之上,使铀矿化进一步富集；确定秀才洞地区成矿构造带原生晕垂向分带序列(由上至下)为:Ga—V—Ni—Zn—Mo—As—Bi—W—Sb—U—Pb—Sr；确定V、Zn、Ga、Ni为铀矿体前缘指示元素,Mo、Bi、As、U、Sb、W、Pb为矿中指示元素,Sr为尾部指示元素。
英文摘要:
      In the recent years uranium exploration in Rucheng County of Hunan province has developed into a medium scale uranium deposit.In order to search for concealed ore bodies and further expand the scale of the deposit, the authors have carried out the vertical zoning of tectonic primary halo within the deposit area.The study shows that the mineralization and enrichment trend of indicator elements are obvious in the metallogenic tectonic of the ore.The uranium metallogenic hydrothermal fluid activities can be divided into uranium -red chalcedony-hematite mineralization、uranium-gray microcrystal-quartz-pyrite mineralization and uranium-fluorite three metallogenic stages.The material composition of ore-forming fluids in different stages is basically the same, and the later mineralization superimposes on the earlier mineralization, which further enriches uranium mineralization. It is determined that the vertical zoning sequence of primary halo in Xiucaidong uranium deposit metallogenic structural belt (from top to bottom) is:Ga-V-Ni-Zn-Mo-As-Bi-W-Sb-U-P. B-Ba-Sr; V, Zn, Ga and Ni are identified as indicative elements of uranium ore front, Mo, Bi, As, U, Sb, W and Pb are indicative elements of ore, and Sr and Ba are indicative elements of tail.
