The regional metallogenic geochemical theory focuses on the research of geochemical law during the formation of giant deposits. Based on the framework of geological process and mineralization series, the theoretical system consists of the geochemical block theory of mineralization, the geochemical anomaly series theory, and the geochemical secondary and primary zonation theory. Under the guidance of this theoretical system and according to the work procedure of geochemical exploration including regional, general-survey and detailed geochemical exploration formed during the past decades, the regional mineral resource geochemical assessment system and the regional geochemical exploration techniques have been established, which can be used to study the geochemical phenomenon related to mineralization and exploration on different scales. This paper mainly discusses the theoretical system of regional metallogenic geochemistry and related assessment system as well as methodology based on the assembly of regional geochemical anomalies in Tuotuo River region of the north Three-River mineralization belt, southwest China. the geochemical block theory of mineralization; the geochemical anomaly series theory; the geochemical secondary ©, 2015, Chinese Academy of Forestry.
