Bangong Lake (Bangong Co) ophiolite, Rutog (Ritu) Co., Ngari Prefecture, Tibet Autonomous Region, China

The ophiolite zone contains numerous carbonatite bodies that are intimately associated with ultrabasic rocks. They occur as small stocks or dikes and are several tens to several hundreds of meters wide. According to their chemical compositions, they can be subdivided in calciocarbonatites (consisting mainly of calcite) and magnesiocarbonatites (consisting mainly of magnesite and siderite).
