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

橄榄岩虽然发生强烈蛇纹岩化（现在为蛇纹岩），但蛇纹岩中和橄榄的假象。

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

单和均发育出溶结构，出溶条纹或者平直或者发生舒缓的弯曲变形（即便是在发生弯曲的情况下也是完全平行的）。
