| Re-Os isotopic composition of the Dongling ⅢCD iron meteorite |
| |
| 摘 要： | Re, Os concentrations and Os isotopic compositions of the Dongling ⅢCD iron meteorite were determined by N-TIMS technique. The result was compared with that of the other irons and chondrites. The Re and Os concentrations of the Dongling iron meteorite were plotted on the trends of the group ⅢA and ⅣA irons. The Pt-Os relation of the Dongling iron meteorite is similar to that of the group ⅡA irons. That suggests a higher fractionation for the Dongling iron meteorite.

| Abstract: | Re, Os concentrations and Os isotopic compositions of the Dongling IIICD iron meteorite were determined by N-TIMS technique. The result was compared with that of the other irons and chondrites. The Re and Os concentrations of the Dongling iron meteorite were plotted on the trends of the group IIIA and IVA irons. The Pt-Os relation of the Dongling iron meteorite is similar to that of the group IIA irons. That suggests a higher fractionation for the Dongling iron meteorite. |
