Foliated Serpentinite – Location 9


 
Sample : Photo location 9
  Rock name : Foliated Serpentinite  (Turner, 1982)

 

Megascopic description:

Foliated serpentinite, cut by serpentine veins or veinlets. Black patches (euhedral – subhedral) are scattered – probably remnants of pyroxene (?)

Microscopic description:

The thin section of serpentinite shows the foliation structure which is formed by the orientation of serpentine and opaque minerals. The present of spinel and relic of olivine) and pyroxene, anhedral to subhedral in shape, up to 4.0 mm in crystals size, it indicated that their protolith is a peridotite rocks. Olivine and pyroxene usually present to form sea and island texture and mesh structures.
