摘　　要：New occurrences of jadeitite, jadeite quartzites, and jadeite-lawsonitequartzites have recently been discovered in the Rio San Juan Complex （RSJC） of the northern Dominican Republic. These rocks are found in serpentinite mé1anges associated with a former intra-oceanic subduction zone （Fig. 1）. The mé1anges contain blocks of various high-pressure （HP） metamorphic rock types such as blueschist, eclogite, jadeitite, orthogneiss, rare cymritebearing rocks, marble and metapelite.New occurrences of jadeitite, jadeite quartzites, and jadeite-lawsonitequartzites have recently been discovered in the Rio San Juan Complex （RSJC） of the northern Dominican Republic.
