A possibility for the depletion of siderphile elements in chondrules due to the expulsion of iron globules

Abstract

Separation of iron globules from chondrules during chondrule formation process is investigated kinematically. The results of calculation show that if those iron globules were initially inside and transported to the surface of the chondrule, most of them would be expelled from inside to outside due to the surface tension force. The results show a possibility that this process may be responsible for the depletion of siderophile elements in natural chondrules.
