| 摘 要： | 赣杭构造带主要受赣抗断裂带控制。它主要由永丰-诸暨坳陷带、赣杭构造火山活动带和赣杭红盆断陷带构成。赣抗断裂带是由绍兴-江山深断裂发展演化而来,它主要由绍兴-江山、广丰-东乡和抚州-永丰三条深、大断裂构成。该断裂带是一条长期活动带,但各时期地质构造的表现形式和各段动的强烈程度、深度、形成时间并不完全相同。赣抗构造带具明显的继承性。自加里东运动以来,它长期屎持相对坳陷或低地特点。这一特殊构造环境,对铀成矿有利。区内铀成矿经历了漫长的复杂过程,这些过程均与赣杭断裂带活动密切相关。

| Abstract: | Gan-Hang tectonic belt is predominantly controlled by Gan-Hang fracture zone. It is mainly composed of Yongfeng-Zhuji downwarping zone, Gan-Hang voleanic activity structural belt and Gan-Hang red basin downfaulted zone. Gan-Hang fracture zone is derived from evolution and development of Shaoxing-Jiangshan deep fracture. It is principally composed of threedeep and large fractures: Shaoxing-Jiangshan deep fracture, Guangfeng Dongxing deep fracture and Fuzhou-Yongfeng large fracture. The fracture zone is a long active belt, but in each active period, it has not completely same geologic structural patterns and intensive degree, depth and forming time. Gan-Hang tectonic belt possesses obvious inheritance. It has always maintained the character of the relative depression or low land since the Caledonian movement. This specific structural environment is favourable for uranium mineralization. At any rate, the formation of this uranium minerogenetic zone has been experiencing a long and complicated processes which were closely associated with long activity of Gan-Hang fracture zone. |
