Eclogite-bearing garnet lherzolite body, forming a small hill about 0.6 km x 0.2 km in plan view, that is underlain mainly by gneiss. The eclogites contain quartz pseudomorphs after coesite, included in garnet and omphacite. Olivines from this locality contain ilmenite exsolution lamellae.

Located about 10 km SW of Rongcheng.
