Xiangshan uranium orefield is located in the North East of Qin-Hang metallogenic belt and the middle of Gan-Hang metallogenic belt. And

it is the largest volcanic-type uranium orefield we have found in our country.In the nearly 50 years

the research degree of orefield is so high.The ore-controlling characteristics research of Xiangshan uranium orefield is not a fresh topic. The theory of interface controlling uranium deposits has been further enriched these two years. The most of ore deposits which had been found in northern of orefield were possessed by thrust nappe. But less information were involved in the related ore-controlling roles.In this area

the basite hasn’t attracted much attention.The characteristics of the basite will be briefly introduced by the author. For a long time

Zou-Shi fracture was considered to be the main fracture controlling ore body. But recently

there has been a new discovery

which has raised questions about the previous conclusions.
