【Abstract】 In this paper, the forms of migration, the mechanisms of deposition and the existence states of gold would be discussed. Based on reviewy a number of materials of gold ore deposits, it may be suggested that the migration of gold is mainly in the form of colloform, simple haloids, different complexes and mechanical form.In the minerogenetic course, gold deposited and concentrated by mechanical or by the agents of absorption, coagulation of coloid and reduction from the gold bearing solution.In the crust of the earth, gold occurs as a native metal, gold minerals, isomorphism （gold-bearing minerals） and absorptive forms of colloid.At the stage of magmatism, gold occurs mainly in mafic rock-forming minerals as the native metal, but also occurs in combination with other elements.At the hydrothermal stage, gold may also occurs as the native metal, but in combination as a minerals with other elements. Such as sulphur, tellurium etc.In the course of exogenetic action, gold is occured as a absorptive form of colloid by absorption of colloidal Fe（OH）₃, SiO₂, organic materials and clay mineral.更多还原
