摘要
The major gold deposits in East China are characterized by their occurrence in pre-Cambrian host metamorphic rocks, restriction in some specific stratigraphic-structural terranes,tendentious localization in ductile or ductile-brittle shear zones, association with the syntexis-type granitoids, and significant remobilization, superimposition and enrichment by the later-stage Mesozoic tectono-magmatic activities.
