High precision geochronological data of gold related rock mass are less in the eastern Guangdong Province. And studying the rhyolitic porphyry related to gold—polymetallic mineralization will be very important for understanding the evolution of volcanic rocks and the relationship between volcanic rocks and gold mineralization. The Honggoushan rhyolitic porphyry is closely related to gold—polymetallic mineralization, which is in the central part of Lianhuashan tungsten deposit, eastern Guangdong Province, South China. It is a newly discovered gold deposit in recent years that having gold prospecting potential. On the basis of field geological investigation, we choose the typical rhyolitic porphyry and mineralization of samples in order to detailed study on the Honggoushan ore block. Zircon UPb age analysis for rhyolitic porphyry weighted average 206Pb/238U age was 169.1±1.5Ma. Trace element characteristics show that the porphyritic granite depleted in Ba, Sr, HF elements Nb， P， Zr， Hf, and enriched in Rb, HF elements U， Ce， Sm and La， Nd. Rhyolitic porphyry has similar rare earth elements characteristics with ore with Eu moderate negative anomaly. However, with the increase of mineralization intensity, REE is more enriched.The εHf(t) values of rhyolitic porphyry constraint widely（-15.0～2.2）. Moreover, the ages of second stage is between 1.946Ga and 2.788Ga. Rhyolitic porphyry formed in the middle Jurassic, materials sources mostly derived from the partial metling of Paleoproterozoic, and Neoarchean crustal metamorphic shale and sandstone with the input of mantlederived magma. Therefore, it is a great significance to focus the research on the midJurassic rhyolite porphyry for the discovery of W, Cu, Pb, Zn, Bi, Au, rare earth, rare and dispersed elements of mineral resources.
