Scientific paper

The Sm-Nd system for the Divnoe meteorite was investigated. For a whole rock fragment we measured a value of Epsilon143=192.1 +/- 0.5. The calculated model age relative to CHUR is 4.62 +/- 0.07 Ga. An excess of 142Nd (Epsilon142=+6.7 +/- 0.9) indicates the presence of live 146Sm at the time of meteorite formation. The calculated initial ratio 146Sm/144Sm is 0.0116 +/- 0.0016
