| 中文摘要: |
| 建兴沉积盆地位于伊春—延寿地槽褶皱系与松嫩坳陷的耦合部位,是一小型断陷盆地。盆地的基底(蚀源区)由新元古代一面坡群和加里东中期正长花岗岩组成,构成该区砂岩型铀矿床的主要成矿物质来源。盖层主要由下白垩统建兴组组成,系一套河—湖相陆源碎屑赋铀含煤沉积建造,该组内沿构造斜坡带发育有十几层砂体,含矿砂体及其顶底板在垂向上具“泥—砂—泥”结构,本矿床共圈定12层铀矿体,通过地质工艺条件实验研究,初步获得了矿石的可地浸地质工艺参数,确定了溶浸剂的种类、浓度,为现场试验提供了依据。 |
| 英文摘要: |
| Located in junction part of Ynchun- Yanshou geosyncline folds and Songnen dispression,Jianxing Basin is a small size fault-cause basin within uplift.The base of this basin consists of Yimianpo group(Neoprotezoic) and orthoclase-granite(Caledon stage),and become sources of sandy type uranium deposit. Upper Cretaceous Jianxing sets composits the mainly cover,is lake facies sediments formation from terrigenous genesis,and inside develop tens bedding sandy body along the slope of tectonic,and in its vertical section own strturucal as mud-sand-mud,totaling 12 layers uranium orebody have been outlined.After geological and technical condition study in laboratory,the parameter of leach technical has been getted,and type and desity of dissovlvant has been deterimined,all of those offering well-founded for on situ testing work. |
