Trace element geochemistry and PGE potential of noritic bodies from Uauá block, Bahia - Brazil

Preliminary field relationship and incompatible trace element geochemistry on two bodies of noritic rocks from Uauá area are discussed with the aim of evaluating their metallogenic potential. The rocks show primitive mantle normalized and chondrite normalized patterns very similar to chilled margins and parental magmas to the Bushveld and Insizwa complexes (RSA) which host major platinum group elements deposits. The data suggest the Uauá noritic bodies may be potential for ore mineralisation.Preliminary field relationship and incompatible trace element geochemistry on two bodies of noritic rocks from Uauá area are discussed with the aim of evaluating their metallogenic potential.
