Abstract The epicontinental region of Northeast China in the compounding part of Paleo-Asia Ocean and marginal-Pacific tectonic domain, where the tectonics and magmatism were intensively developed, is one of the significant sources for nonferrous and noble metal deposits of the country. Based on a detailed study on geology, geochemistry and metallogenic background of typical ore deposits, combining modern metallogenic theories, a classification system is established for the nonferrous and noble metal ores in the region. Through the division to the tectonic elements and the establishment of evolving sequence of regional tectonic thermal events, four stages of the regional tectonic evolution are recognized. The mineral resources of nonferrous and noble metals richly conserved in the region are generally classified into two systems, i.e. the simple metallogenic system and the compounding metallogenic system, which are further divided into various subsystems under different tectonic backgrounds.
