Analysis of trace elements in calcite before and after mineralization at Mianhuakeng uranium deposit

and contrast with the normal granite

to explore the rich uranium ore forming fluid properties and calcite mineral sources. The research show that: Value of highly compatible elements Cr

Co

Ni in calcite sample contain was similar with alteration rock’s and ore bearing granite’s

but significantly different with mafic dikes’ s. In the scatter plot of La/Ho-Y/Ho

calcite samples at different stages in a same horizontal line

showed that the homology of all calcite samples. The rare earth element distribution curve of calcite was quite similar with alteration rock and country rock of granite

but significantly different with diabase’s

showed that the metallogenic material of calcite may originate from ore bearing granite

rather than diabase.
