Scientific paper

The chemical compositions of the Ningqiang carbonaceous chondrite matrix and a dark rim are analysed with instrumental neutron activation method. The results indicate that there are more abundant light REE and chalcophile elements in the matrix of Ningqiang than in the whole rock sample of Ningqiang, and it roughly exhibits a similarity of REE model between the Ningqiang and Allende matrices. The difference between the dark rim and Ningqiang matrix is that the former has richer FeO and poorer refractory elements. It is deduced that the meteorite matrix and the dark rim came from different source material regions of the solar nebula.
