| 内容記述 | The volatile contents of a number of enstatite chondrite falls of different chemical groups (EH; EL) and petrologic types (EH3-5; EL6) were investigated in order to find evidence of explosive pyroclastic volcanism, supporting the mechanism proposed by Wilson and Keil (1991) to explain the lack of aubritic basalts in aubrites. It is shown that abundant volatiles are likely to have been released upon partial melting of enstatite chondritelike precursor materials of aubrites, enough to drive pyroclastic volcanic eruptions which would explain the lack of aubritic basalts. |
