橄榄石是构成超基性岩的主要造岩矿物,同时也见于其它岩浆岩、变质岩、陨石以及月岩中。长期以来,对橄榄石、含橄榄石岩石以及含橄榄石体系进行过较多的野外和实验研究。近年来,在橄榄石研究中又提出了一些新问题和新看法,现就其中的某些问题作一介绍,供参考。 Olivine is the major rock-forming mineral that constitutes ultramafic rocks and is also found in other magmatic rocks, metamorphic rocks, meteorites and lunar rocks. For a long time, there have been many field and experimental studies on olivine, olivine-containing rocks and olivine-containing systems. In recent years, some new problems and new opinions have been put forward in the study of olivine, and some of them are introduced briefly for reference.
