| 摘 要： | 运用矿液致裂理论与多种测试技术,详细研究了桂北苗儿山矿田花岗岩型脉状铀矿床矿脉的形态与内部结构,获知成矿时矿液的压力大于围岩的静压力,矿脉由矿液压裂作用形成。在此基础上讨论了矿液致裂对花岗岩型脉状铀矿床多期成矿的控制。

| Abstract: | Morphologies and intertexture of ore veins in vein shape granite-type uranium deposits in Miaoershan ore field in north of Guangxi are studied in detail through using the hydraulic pressure cracking theory and various kinds of testing technique.It is known that the pressure on ore fluid is larger than that of wall rock,and the ore veins are formed by hydraulic pressure cracking.Based on the above discussion,the control of hydraulic pressure cracking on the multiphase metallogenesis of vein shape granite-type uranium deposits is discussed. |
