摘要：

Linglong granite is the main wall rock of ore bodies in Huangbuling gold deposit, Zhaoyuan. The main alteration in the deposit includes red alteration, sericitization and carbonatization. The orebodies occurred mainly in the sericitized zone. Compared with fresh granite, content of TiO(2), Al(2)O(3), FeO, CaO, Na(2)O, MnO decreased in the altered rocks, content of SiO(2), K(2)O, MgO, Fe(2)O(3), CO(2) and H(2)O(+) also changed regularly in the altered rocks. From fresh Linglong granite to red-altered granite then to sericitization, Sigma REE, Sigma Ce/Sigma Y, delta Ce, delta Eu and La/Sm ratio decreased and Sigma Y increased gradually Compared with fresh granite, content of Fe, Mn, Pb, and Zn decreased in red-altered granite and increased remarkably in the scricitized zone. The ore-forming fluid was rich in sulfate and CO(2). The Huangbuling deposit formed during circulation of meteoric water driven by lithosphere- mantle thermal convection.
