| Thesis is center on rocks,geochemical go on systematic discuss for theNeoproterozic-Caerfai Volcanic Rock in Quruqtagh.through inquire into andunderstanding to the volcanic rock in background,Petrogenesis,character of source andperiod,in the same time,also research the mineralization system of this area.With the helpof geochronological and geochemical research,we use these data to analyse and researchto offer important evidence for the tectonic evolution,the spliting of Rodiniasupercontinent in Qurqtagh of the Precambrain.Through systematic research character of the geochemical in rock,geochemical,REE andtrace elements and the discuss of the character of mineralization system in this area,andcombine to region geology data,some conclusion has been drawn:the Neoproterozic-Caerfai Volcanic Rock in Quruqtagh were formed in a extend tectonicbackground,should be the continental- rift environment;the petrogenesis relate to the riseof mantle plume,the source have a stable region with garnet-lherzolite and thegarnet-lherzolite been transition into spinel-lherzoliet.when they were formed ,thecontinent crust was becoming thinner,was pulling and spliting open,was a express of thespliting of Rodinia supercontinent in Qurqtagh and a petrological record of the breakupevent of the supercontinent Rodinia, which also reveals the Tarim movement,and puttingforward that continental rift volcanic activity from Neoproterozic to the early stage ofearly Cambrian is the auspice of the opening of the Paleo-Asian Ocean. Qieganbulakeapatite-vermiculite deposit and Xingdi II Cu-Ni deposit in xinjiang were formedNeoproterozic(Nanhua),the background of mineralization motive force were the breakup event of the Rodinia supercontinent,it was a important period,we shouldn'toverlooked,there are having very much unusual of navigate-magnetic,may be caused byultramafic and mafic complexes,and the further-work should take up,there were have aglorious prospect of mineralization and potential resources.
