元素共生分异及水岩反应与乐马厂式独立银矿床成矿

Elemental paragenesis and separation is the nature of deposit zonation, and also is the cause of forming independent silver deposit, while water/rock interaction is the reason of wall-rock alteration of hydrothermal deposit and the main mechanism of elemental paragenesis and separation. The study of mechanism of elemental paragenesis and separation during water/rock interaction can reveal the genesis of independent silver deposit, and further can provide direction of regional exploration. Accordingly, this also enriches the theory of forming silver deposit, and promotes the study and application of water/rock interaction theory.

元素共生分异是矿床分带的本质，也是形成独立银矿床的根本原因；水岩反应既是形成热液矿床围岩蚀变的原因，也是导致元素共生分异的主要机制。通过研究水岩反应过程中的元素共生分异，进而探索影响元素共生分异的因素和机理，揭示独立银矿床成因，为进一步区域找矿提供理论依据和方向；同时也将丰富银的成矿理论，促进水岩反应理论的研究和应用。
