Starting with the study of geo logical background,the present paper deals with the Guantian Cu Tebearing pyrite deposit in East Guangdong in te rm s of its geochemical characteristics and relation to volcanic events, and eventually gives a clear idea of its zonation of mineralizing elements.The research reveals that volcanic hydrothermal solution was a key to the origin of the deposit when it was mixed with gas or liquid caused by late evolution of complexes and then moved into a series of faults.In the course of movement,the solution was joined by much meteorological water,leading to intensive pyritequartz sericitization,and extracted such elements as Pb,Zn,etc. from the bypassed detrital roc ks with the decrease of temperature, promoting PbZn mineralization in the nort h.Accordingly,zonation of minerali zing elements was created from south to north.
