| Abstract: | The deposits No. 325 and No. 326 lie in the middle zone of ZG composite granite bodies. They belong to uranium deposits of granitic type. Before the ore-forming stage the mineralization fluid mainly came from the magama hydrothermal solution. In ore-forming stage the mineralization fluid was the mixture of magama hydrothermal fluid and meteoric water and after ore-forming stage, the meteoric water rain. Studying from isotopes of sulphur and lead made it clear that the ore-forming materials of the deposits mainly came from granite bodies and partly came from the stratum of Cambrian system which is around the deposits. The soda-metasomatism has importance to mineralization. It changed the physical and mechanical property of rock and cause uranium mobilization and transference. The structure controled the distribution of the mineral bodies. |
