【Abstract】 In the territories of Jiangxi, Fujian and Zhejiang provinces there have widely developed a kind of particular medium-acidic igneous rocks of mesozoic and caenozoic, with the features possessing in lava,volcanic arenite and subvolcanic rock. The main rocks from Xiangshan volcanic basin in Jiangxi are the most representative of the areas mentioned above. However, in regard to the problems of their nomenclature and genesis there is still existence of greater controversy. Owing to that these rocks are genetically related to the uranium deposits, they have received considerable attention from geologists in a long period of time. The results in studing inclusions of the main rocks from seven volcanic basins show that the glass inclusions are well developed in these rocks which display aneruuotive feature.The temperatures for formation of the rocks are as high as 1200℃. According to the features of inclusions, the main rocks can be divided into Xiangshan type and Gaojia type. The study on inclusions also shows that the combination of high-saline fluid inclusions, the inclusions containing CO₂ and belling fluid inclusions may be served as an important information indicating the environment favorable for mineralization of uranium deposits.更多还原
