| 摘 要： | 新疆白杨河铀矿床是我国目前已探明的中型矿床,矿床蚀变特征的研究有助于对白杨河矿床外围及深部找矿提出更好的找矿认识。使用ASD可见光-短波红外地面光谱仪对白杨河矿床地表以及钻孔岩心进行光谱测量,发现了矿床中蚀变矿物主要有高铝绢云母、中铝绢云母、低铝绢云母、绿泥石、蒙脱石、赤铁矿、褐铁矿等。矿床地表铀矿化异常地段主要发育高铝绢云母蚀变;钻孔岩心中铀矿化富集部位蚀变矿物组合为高铝绢云母、绿泥石、赤铁矿。研究结果可为矿床外围及深部铀矿勘探提供参考与借鉴。

Application of ASD Spectrometer to the Study of Alteration Information in Baiyanghe Uranium deposit,Xinjiang |

| Abstract: | Baiyanghe Uranium deposit is an identified medium‐size deposit in Xinjiang ,China. The study of the deposit can provide better understanding for peripheral and deep ore prospecting of this type mine‐ralization zone. In this paper , the spectrum of Baiyanghe’s surface rock and drilling cores were measured by ASD visible‐shortwave infrared spectrometer , and the results shew that the ore body of main hydro‐thermal alteration minerals are highly coodinated Al sericite , middle coodinated Al sericite , low coodi‐nated AL sericite , chlorite , montmorillonite , carbonate , kaolinite , hematite and limonite et al. Highly coodinated Al sericite and hematitization abnormal region of the deposit surface is uranium mineralization abnormal region. Alteration mineral assemblages of uranium enrichment section are highly coodinated Al sericite and chlorite in the drilling cores ,and the hematitization is also rich. Therefore , these can provide information and reference to the peripheral and deep uranium exploration. |
