 note = {P(論文), Oxygen isotopic compositions (^<18>O/^<16>O and ^<17>O/^<16>O) of five Yamato meteorites have revealed that Yamato-7303 (m), -74190,-74191,and -7308 (l), -74013 can be classified as L ordinary chondrites and differentiated meteorites, respectively. The former three meteorites may have been derived from one parent body, and the latter two meteorites are from another parent body in the solar system.},
