| Abstract: | The volcanic-intrusive complex of Tianfezai is the only widespread terrestrial acidic vol-canics in North Guangdong-South Hunan area, where there are a few of uranium occurrences.Based on the study on volcainc-intrusive complex, its occurrence characteristics, petrology andgeochemistry characteristics are discussed as well as division of volcanic sequences and volcaniccycles, classification of volcanic facies and volcanic structure types are suggested. |
