The volcanic rocks of the Xiong'er Group is also widespread in the Baoji and Lvliang area and also appear as 1.75Ga-old mafic dyke swarms, A-type granites, later anorthosite and rapakivi granites (1.75-1.70Ga), and alkaline granitoids (~1.65Ga). These intrusive rocks are assumed to have genetic link to the volcanic rocks of the Xiong'er Group.

Therefore, the chiru attracted a lot of attentions of the Chinese government, conservation scientists and other conservative organizations in the world.In the present study, 57 chiru individuals were sampled from Arjin Shan Nature Reserve in Xinjiang, Chang Tang Nature Reserve in Tibet and Kekexili Nature Reserve in Qinghai. The present study, based on the analyses of the chiru mitochondrial control region with MEGA, DnaSP and ARLEQUIN programs, investigated into the genetic diversity background, evolutionary history and population relationships and aimed to provide scientific basis for the protection of the chiru.
