摘　　要：我国碱性侵入岩分布十分广泛,且常沿两大构造单元之间或古老大陆边缘的深断裂带分布。深断裂是控制碱性岩上侵定位和控岩控矿的构造,碱性岩侵入体常呈串珠状沿深断裂作线状延展,形成14条岩带,将与其有关的内生金属矿床分为12类。并对白云鄂博、牦牛坪、东坪和巴哲尔等矿床的地质特征进行了研究,还将与碱性侵入岩有关的金属矿床分为与正长岩类有关的矿床和与碱性花岗岩类有关的矿床两大类。Most of the alkaline intrusions in China are distributed along deep fracture zone of the continental margin as a Chain. Based on the data of 187 alkaline intrusions in China it may be divided into 14 alkaline intrusive rock zones distributed along deep fracture zone. 12 tyeps of metallic ore deposits related to the alkaline intrusions in China may be presented and geologi-cal features of 4 important ore deposits are described. The 4 ore deposits, including the bayan Obo Nb-Fe-REE deposit of Inner Mongolia, the Maoniuping REE deposit of Sichuan preovince. the Dongping Au deposit of Hebei province and the Barzhe Be-Nb-Zr-REE deposit of Inner Mongolia are characterized by large-scale mineralizations and the Bayan Obo de-posit is well known as a super large REE deposit in the world.
