The Taojiang-Chengbu fault zone is one of the main reactivation faults in the "aulacogen" of Central Hunan. Owing to repeated reactivation, the fault zone is characterized by large scale, deep dissection and evident rock- and ore-controlling effect, and is the important ore-controlling fault zone in Central Hunan. The northeastern part of the fault zone refers to the section from Liaojiaping, Anhua in the southwest to Banxi, Taojiang in the northeast, totaling 40 km in length. The section mainly cuts two structural beds, the Xuefeng and Caledonian strata. There occur middle- and large-scale vein antimony ore deposits along the fault zone, which has increased the prepotion of antimony reserves of Central Hunan. New recognition is proposed in this paper based on the study of types and features of the deposits, association type of ore-controlling structures, metallogenic law and metallogenic-prospecting model of the antimony deposits. Based on the proposed model, the Dafuping antimony deposit and the Liaojiaping gold deposit were predicted and inferred to be a middle- and a large-scale deposit respectively.
