Jade locality 120 kilometers northwest of Mogaung.
Transformation zone environment of an ophiolitic complex.
Amphibolites and chloritites at the contact between albitite (plagiogranite) vein (with chromite xenocrystals) and a serpentinite host-rock.
The albitite transformed to jadeitite.
Amphibolites formed by metasomatic reaction during HP/LT metamorphism (hydrous low-T eclogite facies or blue schist facies) (subduction).
Host rocks are magnetite chloritoschists, glaucophane schists and actinolitic schists.
