The study area, Bophi Vum, Myanmar, is composed of the harzburgite, serpentinite and dunite, those are covered by Quaternary alluvium. The chromite ore bodies are developed within dunite and harzburgite bodies, mainly within dunite bodies. To identify the extension of the chromite ore bodies, we carried out trench surveys in the 5 different sites. The chromite ore bodies have 0.3-1.5 m wide, and several meters of extension, and deformed strongly as a sigmoid and a boudin shapes with dunite and harzburgite bodies by ductile deformation. The ductile deformation have a top-to-the-west shear sense, indicating the existence of a westward thrusting. The NW-SE trending distribution of ore bodies is related to the dextral ductile shearing and/or to the block rotation as a book-shelf structure by dextral strike-slip movement.
