Abstract
The orientation of high temperature dikes has been studied with respect to the plastic flow foliation and lineation in peridotites from several massifs. Layering and dikes are composed of various types of pyroxenites and gabbros; dunites, thought to represent residua along high temperature dikes, have been also studied. The layering is composed of dunites, websterites and/or orthopyroxenites, usually with the same minerals as in the host peridotite. The same rock types can be observed in the dikes emplaced early during plastic deformation although the sequence tends to evolve toward more ariegitic or gabbroic facies.This publication has 3 references indexed in Scilit:
