| 摘 要： | 小尖山火山塌陷盆地位于得尔布干多金属成矿带中南段的八大关-新巴尔虎右旗多金属成矿带上，与俄罗斯斯特列措夫铀矿田、蒙古多尔诺特铀矿田有着相似的地质背景。通过对盆地基底、盖层、铀含量、断裂、蚀变、矿化显示等几个方面的调查研究，认为该盆地具备“近带靠边、伴盆独立、酸底凸凹、杂盖多面、主断切壳、蚀变叠加、矿化显示”等铀成矿的有利特征，提出小尖山火山塌陷盆地是寻找火山岩型铀矿床的有利远景盆地。

| Abstract: | Xiaojianshan volcanical collapse basin is located in the Badaguan-Xinbarhuyouqi segment of the mid-south part of Derbugan polymetallic metallogenic belt, and bears the similar geological background to that of Siteliecuofu uranium orefield in Russian and Duornate orefield in Mongolia. Throug the study of basement, overlayer, uranium content, alteration and mineralization, the basin is believed to have the favourite metallogenic condition of acid rock base and overlayer, penetrated mainfault and superimposed alteration. It is suggested as the patential basin for exploring vocalnic uranium mineralization. |
