摘　　要：满洲里地区的小尖山盆地与俄罗斯斯特列利措夫铀矿田、蒙古多尔诺特铀矿田处于同一大地构造单元,有着相似的地质背景。笔者在前人研究工作成果的基础上,结合野外地质调查,对小尖山盆地铀钼矿化控制因素进行分析,认为其主要受构造、火山岩岩性、侵入岩和蚀变等控制。据此,指出了盆地内断裂-火山构造结及燕山晚期斑岩接触带是今后开展找矿工作的重点对象。Xiaojianshan volcanic basin, Siteliecuofu uranium orefield and Duornate uranium orefield are located in the same geological tectonic units and bears similar geological background. On the basis of pre- vious research, combined with the field geological investigation, the U-Mo mineralization of Xiaojianshan volcanic basin was analyzed, and the structure, lithology, intrusive rocks and alteration are considered the main control factors of mineralization. Based on the above study, the key points of the prospecting work in Xiaoiianshan volcanic basin were pointed out for the future efforts.
