A study on chemical composition of Baszkówka and Mt. Tazerzait chondrites

Dybczyński R., Chwastowska J., Danko B., Kulisa K., Polkowska-Motrenko H., Samczyński Z., Sterlińska E., Szopa Z.

The elemental contents of two new meteorites, Baszkówka (Poland, 1994) and Mt.Tazerzait (Niger, 1991), were studied by instrumental and radiochemical neutron activation analysis (NAA), supplemented in the case of some elements by gravimetric, titrimetric, spectrophotometric and atomic absorption spectrometric measurements. In total 28 elements were determined for each meteorite. A striking similarity in the bulk chemical composition of the two meteorites was observed. In the case of Baszkówka some study of the elemental contents of the magnetic fraction and the distribution of elements between kamacite and taenite phases was also made. This study confirms that Baszkówka and Mt. Tazerzait are generally more similar to L chondrites than to any other class of chondrites. However both meteorites show also some distinctive features (e.g very low Hg content), distinguishing them from all other L chondrites known. Both meteorites may derive from a common parent body, which may be different from that typical for other chondrites.
