北天山冰草沟矿床外围铀资源潜力

Uranium Resources Potential of the Periphery of Bingcaogou Deposit in North Tianshan Mountains

以北天山冰草沟成矿带为研究对象,结合冰草沟矿床成熟的成矿理论,分析了该区矿床外围的标志性矿化类型,讨论了不同矿化类型的地质特征和成矿规律以及在地质演变过程中引起铀成矿迁移和富集的因素,并对成矿赋存部位、围岩蚀变、找矿标志、产出环境以及热液蚀变进行了研究,对于该区进一步开展铀矿找矿勘查工作有一定的借鉴价值。

Taking the Bingcaogou metallogenic belt in North Tianshan Mountains as the study example,based on the mature metallogenic theory of Bingcaogou deposit,the signature mineralization type of the periphery of Bingcaogou deposit is analyzed,the geological characteristics and metallogenic regularities of the different mineralization types are discussed in detail,and the influence factors of uranium metallogenic migration and enrichment in the process of geological evolution is also analyzed,besides that,the metallogenic occurrence position,surrounding rock alteration,prospecting indicator,production environment and hydrothermal alteration are studied in depth. The above discussion results related to the uranium prospecting potential of the periphery of Bingcaogou deposit in North Tianshan Mountains can provide some reliable basis for further conducting prospecting and exploration work of uranium deposits in the area.
