A carbonatite dyke, emplaced along a fault that separates coarse quartz sandstone from shale, both members of the Middle Proterozoic Bayan Obo Group. The dyke, which was named for its discoverer, is well exposed over a length of 60 m. It is 1.1-1.5 m wide, strikes NE and dips NW at an angle of about 85°. The wall rocks on both sides are fenitized to a width of 10-20 cm and this alkaline mineralization extends along fractures and joints into the adjacent sandstone, for up to 30 m away from the contact zone. The dyke was affected by later tectonism and is strongly deformed and sheared sub-parallel to the dyke walls.

Located at Dulahala, about 2 km NNE of the East orebody.
