The Dunhua basalts contain a large amount of mantle peridotite xenoliths, and the peridot gems are produced from the peridotite xenoliths with an approximate east–west distribution in a near-horizontal layer. The peridotite xenoliths containing gemgrade peridot from the Yiqisong deposit are mainly spinel lherzolite xenoliths. The peridotite xenoliths have a light yellow or yellow-green color and are sub-rounded to subangular in shape, and were captured by black basalt with clear boundaries. The diameter of the peridotite xenolith is usually 3 to 10 cm, with the larger ones reaching 25 cm.
