摘　　要：对钍在不同地质体中的分布及钍的地球化学演化特征进行了分析；简要概括了世界钍矿床分类，对三类重要钍矿床的成矿作用进行了综述；以钍矿床成矿特征与铀矿床作对比，提出钍矿成矿地质特征，以及钍成矿的特殊性和钍矿床勘查的地质依据，并提出中国钍矿资源勘查对策和发展前景。Three aspects on thorium deposits are discussed： distribution of thorium in different geological bodies and its geochemical evolution features, the classification of global thorium deposits, the ore-formation of three types of important thorium deposits. By comparing metallogenic features of thorium deposits with those of uranium deposits, the authors put forward geologic-metallogenic features of thorium deposits, the speciality of thorium ore-formation and the geological bases of the geological exploration of thorium deposits, the countermeasures and development prospects in exploring thorium resources in China.
