The Yuanshui basin of western Hunan Province, in the 1950-60s, was producing up to 0.6-0.7 million carats diamond from four rich placer deposits, but no economic primary deposits had been found in this area. Geological Bureau of Hunan, Hubei, Guizhou and Guangxi, from the mid-fifties to nineties, actively explored the southeast Yangtze carton for lamproite, which was considered as the potential hosted-rock of these placer deposits. Their respective efforts led to discovery of three important lamproite clusters (i.e. Zhenyuan, Ningxiang and Dahongshan) and other related rocks (Fig.1). Among them, Zhenyuan and Ninxiang areas have been confirmed as weakly diamondiferous lamproites.
