Based on tungsten and tin analytical data from stream sediments of 1∶200 000 Regional Geochemistry-National Reconnaissance Project and the study of elemental abundance of crust and rocks in the eastern part of China, the temporal and spatial distribution characteristics of tungsten and tin in South China Continent (SCC) are discussed in this paper. On the lithology, alkalic feldspar granite and syenogranite, slate, phyllite and schist in basement in the southeast part of South China Block are characterized by high background contents of tungsten and tin. On the temporal distribution, the sandstones and mudstones in basement and cover from the Mesoproterozoic era are enriched in tungsten and tin; the extensive granitoid volcanic-intrusive activities during the Indosinian and Yanshanian periods, in which the alkalic feldspar granite and syenogranite enriched in tungsten and tin played the main parts, reached a climax in the late stage of crustal evolution.
