M18. Serpentinite - Slishwood
 >View Microscope
Fact sheet
Description: 

This serpentinite shows the typical mesh-texture that results from water penetrating fractures in peridotite and reacting with it along fracture walls.  It has a subtle colour banding which in the field is parallel to the main foliation, the same as seen by aligned perthite inclusions in the garnetiferous quartzite which comes from the same place. It seems that the quartzite and original peridotite were strongly deformed, even mylonitized, together at high temperature.
