| Abstract: | Abstract In this paper such minerais as apatite, zircon and biotite from granites were determined and analyzed by secondary ion mass spectrometry (SIMS) for their isotopic ages, REE composition, trace elements and volatile components with an attempt to shed light on the origin and formation environments of the Jinningian granites in the Yunnan sector of the Kangdian (Xikang- Yunnan) earth's axis. The results show that the apatites, zircons and biotites of different geneses possess different fingerprint characteristics. Some correlations have been found between trace elements and volatile components contained in the minerais from granties. |
