Chhumar Mine; Chumar ruby mines
Ruby deposit situated at 4,300 m high in the south flank of Ganesh Himal Massif, about five kilometers west of Ruyil Ruby Mine. Chumar deposit is very close to the northwest boundary of Dhading District, in Lapa VDC. The host rock is a low-grade dolomitic marble aged Lower Paleozoic.
*... Chumar deposit extends east-west for about 550 m, with a central thickness of approximately 150 m. At the west end, the dolomitic body is bounded by a sharp fault trending N60°W, dipping steeply to the northeast. The east end of the body tapers down to a tail, with no fault line at the boundary. Distinct bedding in the dolomite body, which now consists of large, eroded domes, strikes east-west throughout all but the extremities, where it is bent to the northwest, creating a sigmoid shape. The seams, which are about 8 m apart and dip 32°, vary widely in thickness but average about 20 cm; they are sometimes folded on a small scale.
*from Rubies and fancy-color sapphires from Nepal (see references)
