Zhangli gold deposit is a quartz-ice feldspar-fluorite type middle-low temperature hydrothermal deposit hosted in concealed explosive breccia pipe related with alkaline sub-volcanic rocks�� The results of rock chemistry�� REE and isotope analysis indicate that the ore-controlling rock can be divided into two series including: �� high--K calc-alkaline rock series��which SiO2 content is 57. 6% on average��total rare earth is 373. 98 × 10 -6 �� 297. 43 × 10 -6��δEu is 0. 85 �� 0. 82��Sr is 0. 704 41; �� high--K alkaline rock series��which SiO2 content is 56. 65% on average��total rare earth is 371. 19 × 10 -6 �� 41. 62 × 10-6��δEu is 0. 89 �� 0. 93��Sr is 0. 717 11�� The two rock series were formed by different mantle magma��which experienced long differentiation��and mixed partial crustal material in rising process��and the ore-bearing hydrothermal solution came from alkaline sub-volcanic rocks��
