Peridotite has undergone strong serpentinization and was completely replaced by serpentinite, but the pseudomorph of olivine and orthopyroxene still are preserved.

橄榄岩虽然强烈蛇纹岩化（现在为蛇纹岩），但蛇纹岩中保留斜方辉石橄榄石的假象。

Both clinopyroxene and orthopyroxene show exsolution texture.The exsolution rods generally are parallel each other no matter they are straight or curved.

单斜辉石斜方辉石均育出溶结构，出溶条纹或者平直或者舒缓的变形（即便是在的情况下也是完全平行的）。
