Abstract:

Yangshan ultra-large gold deposit is the first discoveried deposit of more than 300 tons of gold resource in China and even whole Asia.The relationship of the deposit and the granites in orefield is very close.We discuss the characters of plagioclase granite porphyry and granite aplite esposed in Yangshan area from the start of geochemistry characters of granites in Yangshan deposit.Yangshan granites belongs to calc-alkali magma series and superperaluminous.The higher differentiation index （71.12 ~87.0） indicates the intense differentiation of origin magma.The partion chart of rare earth elements is right deviation,lower ΣREE（32.18×10-6~100.21×10-6）,the major of LREE/HREE upwards seven.High field strong elements （Nb、Ta、Zr）are negative anomaly and Rb/Sr is 0.38~2.08.From the discrimination diagrams for the tectonic settings of granites,Yangshan granites comed from the settings of post collision.There are no clearly different except for the intruding time between two types of granites,and they resulted from a homgenous magma synthesized the revolutional history of district geology and age of granites from earlier studies,we conclued that the Yangshan ultra-large gold deposit formed during the post-collision extension between the North China block and the Yangtze block.

Key words: West Qinling, Yangshan gold deposit, Granites, Geochemistry
