Abstract

The neutron activation analysis of the Yanzhuang meteorite has been conducted by several investigators. The results of their investigations indicate that the major and trace element compositions of the Yanzhuang chondrite are similar to the average composition of H-group chondrites. The analyzed samples were taken from different shock phases of the meteorite, especially from melt veins and melt pockets show the compositions similar to that of unmelted chondritic rock. Even the contents of volatile elements like Na, Zn, and Se show no noticeable differences in samples of different shock degrees. Only a certain magmatic differentiation process had taken place in the large melt pockets.
