摘要
3101地区是广西苗儿山铀矿田的重要铀成矿区,3101矿床在1966—1974年由310大队详查确定为中型矿床,2006—2008年进行矿床深部及外围普查,将该矿床提升为大型矿床。本区发育有一组近等间距分布的北西向裂隙群带,对应于主要的裂隙群带地表210Po晕圈反应明显,它们与北北东向主含矿带的复合部位正是北北东向主含矿带内矿体群的赋矿地段,走向上矿体以间距200-250m呈韵律性分段成群分布,倾向上在相近高程上见矿的几率高,矿床内有较多的矿体位于相同高程而产于不同的含矿带内,矿体及矿体集中段的走向长度均小于倾向长度,这些均与北西向裂隙带组发育有关。因此,北北东向含矿断裂带与北西向裂隙群带的交迹既是本区的找矿标志,又是找矿模式,是指导矿床深部及外围找矿方向的标志。
3101 erea is the important metallogenic province of uranium ore in Miao' er Mountann Uranium Mine Concession of Guangxi. 3101 Deposit was definited to be medium sized deposit through detailed survey from 1966 to 1974 by Geological Group No.310 of Guangxi for Nucleus, and it was definited to be large scale deposit through census preliminary in deep part and outskirts around deposit from 2006 to 2008. 3101 erea haved a set of near graduation space distribution of towards north-west (290° ± ) cranny group region. There were distinctive reaction of 210Po halo in the earth' surfaces to the corresponded central cranny group region. They were the plat endowed with mine in the complex region between north-west (290° ± )cranny group region and north-north-east primary region contained uranium ore. Orebodies distributed subsection to show rhythmicity in group within 200-250m.There is a high probability to appear to be mine in similary elevation along its tendency. Orebodies were located in identical elevation, originated in defferent ore bands. The length to striking direction is longer than the length to dipping direction in orebodies and orebodies centralizing convergency section. All these geologic feature were related to north-west cranny group's development. Therefor, the intersecting locus is the mark of prespecting in the complex region between north-west cranny group with north-north-east primary region contained uranium ore , also a prespecting model. It's guiding model for prespecting in deep part or surrounding in deposit.
