Through the research on the pluton's trace elements,REE,Isotope such as sulphur,lead,oxygen,and so on,it is believed that silver deposit and gold deposit's ore materials come from deep-seated magma,large quantity of dark inclusion is one of the main ore materials,under the influence of the deep rooted fracture dissection,ore materials enrich the deposit after .

The genesis of siliceous rocks in the Changkeng gold-silver deposit, Guangdong Province;

From south to north there exist copper,molybdenum and gold-silver deposits,copper ore and gold metallization in turn in the studied area,which are distributed as belts in directions WE and NS.

： Zhilingtou gold－silver deposit is a Yanshania volcanic－subvolcanic lower－median temperature hydrothermal deposit． The REE and Pb，S isotopes indicate that ore－forming material derived from volcanic－subvolcanic hydrothermal solution
