dispersed elements
4.The southwestern Yangtze block, located in the combined zone of Tethys and circum-Pacific tectonic domains, has undergone a complex geologic-tectonic evolutionary history since late Archean. Among various kinds of mineral resources in this area, Pb-Zn deposits are characterized by enrichment in dispersed elements such as cadmium (Cd), gallium (Ga) and germanium (Ge).
