Abstract: The enstenite and its melt inclusions picked up from mantle xenoliths at Longgang volcanoes in Jilin province are measured by synchrotron radiation X-ray microprobe techniques. Some element contents, such as K,Sc,Ti,Cr,Mn,Fe,Co,Ni,Cu,Zn,Ga,Sr,Y are calibrated by NIST SRM 612. The relative deviations of element contents analyzed in enstenit between X-ray fluorescence microprobe and wavelength dispersive electron beam microprobe are 15%,5%,7% and 8% for Cr,Mn,Fe,Ni,respectively. Chondrite normalized transition metal elements distribution pattern of inclusion is similar to that of whole rock analyzed by INAA, which implies that primitive magma experienced partial melting or segregation during ascending.
