[en] The paper studies caused uranium volcanic texture, distribution of volcanic uranium mineralization and existing rule according to the interpretation of ETM+ map for the volcanic rock belt in the east of Xuemistan volcanic rock belt which is about 130 km in length, 15∼20 km in width. Caused uranium volcanic texture distributes mainly in Yangzhang-Bayinbulak fault and its north, such as Yangzhang, Yinisala, Bayinbulak, Shiyue, Hakedun volcanic texture ect. Break forth type form west to east is focus model that transited cranny type gradually. Form west to east, the denudation of volcanic texture increases gradually, and Uranium mineralization becomes volcano breaking type from subvolcanic type. At present, more uranium mineralization discovered in the margin of volcanic apparatus, it is belong to late tectonic mineralization. Other uranium mineralizations lie in the bowel of volcano channel, but we have not developed profundly anatomize. It is suggested that further studies and prospecting work in volcano channel should be enhanced. (authors)
