Study On Petrology Characteristics And Ore Bearing Of Lamproite In The Southwest Margin Of Tarim Platform

Bas ing upon Tar im p1atform s tructure feature and HeTian founded diamond- Theauthor s tud ies on the character is t ics (petro1ogy, geochemi s try, mineralogy) of 1amproi tedike in Tarim platform South West margin (or North margin of West kcolum) and di scusses thenature of magma source that is temperature, press and depth. Comparing with thesecharacteris t ics from different area lamproi te, the author suggests that thesecharacterist ics are different from those of West. Austral ia,. byt s imi 1ar to those ofYinNiuGou lamproi te. The resul t shows that KeLiYang 1amproi te is not typical, but transfersto minet te. I t is not the source rock of HeTian founded diamond. At the same t ime, the resultis a bas is of structure evolvement and a way of finding diamond origina1 mine.
