In the massive eclogites, the garnets with low dislocation density and with no visible clusters of water molecules are mainly rigid although a few dislocation nets have been observed.

块状榴辉岩中石榴石的位错密度低，没有观察到水分子团，虽然在局部发现有位错网，但总体上仍呈刚性。

And clusters of water molecules within garnet are very important evidence of the existence of fluid during ultra-high pressure metamorphic process.

而石榴石中的水分子团为超高压变质过程中有流体存在提供了有力的证据。
