Granite-type uranium deposit is a kind of uranium type

which has important economic value. In this paper

we apply many methods such as thin section

Artificial heavy concentrate test

electron probe microanalysis and so on to study the uranium ore of 6214 granite type uranium deposits. According to the test results

the uranium ore occurrence state of uranium is mainly existed in pitchblende

little existed in coffinite

brannerite and uranothorite; Pitchblende has granular shape

clouding

spotted and impregnated shape distribution and it is closely associated with feldspar

apatite

pyrite.
