Abstract
The greenstone belt and metamorphosed microclastic rock-type superlarge gold deposits in China are hosted in metamorphic rocks and later intrusive bodies. Sedimentation, regional metamorphism and mineralization contributed a lot to the formation of the deposits, so did remelting magmatic process to some deposits, but the deposits were finally formed by reworking processes. The key factor leading to the formation of superlarge gold deposits is the reworking intensity, which for superlarge gold deposits is reflected by the large-scale reworked source rocks and even ore materials of various sources, strongly oxidized ore-forming fluids with a long and repeated active history and stable geothermal heat current. The factor which decides the reworking intensity is the network consisting of structures of different classes.
