摘要
Though the clinoenstatite is a stable phase of the end member MgSiO_3 at lowtemperatures in many experiments,it appears only in meteorites and boninite innature.The ultrastructures of polymorphs of clinoenstatite in meteorites have beenwell documented(Buseck,P.R.,1975;Buseck,P.R.,1980;Coe,R.S.andMuller,W.F.,1973).Here are reported the different characteristics ofclinoenstatite ultrastructures in boninite.Meanwhile,the observations of the G.P.zones in two bronzites are also presented.
