摘要
新疆准噶尔盆地西北部扎伊尔、雪米斯坦两个火山岩带是全国铀资源潜力评价划定的重要的铀成矿区带之一,已发现一系列重要的铀矿床、矿点、矿化点。本文通过对这些铀矿床矿点的资料收集和实地工作,总结了新疆准噶尔盆地西北部的铀矿化特征:矿化以次生铀矿物为主,伴生萤石、高价铁、锰矿化蚀变,受次级断裂/裂隙控制,矿化时代多在二叠纪及其后。将铀矿化划分为3大类、5主类、7亚类,对不同类型的铀资源远景进行了评价:潜火山岩型和火山-沉积碎屑岩型为主,花岗岩型次之,重视沉积-改造砂砾岩型的找矿远景。
Outlined as two of the important uranium metallogenic belts by Evaluation of Uranium Potential in China,Zhayier and Xuemistan volcanic belts in northwest Jungar Basin have many uranium deposit,occurrences and mineralizations found.This paper summarizes the characteristics of uranium resources in both belts through the former data and the field work,finds that the uranium minerals are mostly epigenic,the alterations always include fluoritization,hematitization/limonitization and molybdenumization,the mineralization is controlled by sub-level fault/fractuers,and the ore-forming ages are mostly no earlier than Permian.The uranium resources are classified into 3 general types,5 types and 7 sub-types,each of which the perspectives has been evaluated for.The sub-volcanic type and volcanic-sedimentary clastic type are most perspective,and then the granitic type,and besides,the sedimentary-transformed sandy conglomerate type should be paid attention to.
