二龙抢宝背斜隆升导致F_4断层上盘岩块在重力作用下向北滑坡,泥堡氧化矿体几乎都限制在滑坡体中。因而滑坡堆积是氧化矿体的主要成矿机制。原生矿石在滑坡时与围岩混合造成矿石贫化,但混合矿石同时发生碎裂和扩容作用,增大其孔隙度和渗透性,在表生作用环境下载金含砷矿物得以部分分解而成为易选冶氧化矿石,深入研究滑坡堆积过程的氧化机制有利于提高该类矿床黄金资源利用率和地质勘探程度。
Erlong grab the treasure anticlinal uplifting led to the F_4 fault on the plate rock landslide northward under the action of gravity, almost all of the mud Castle oxide deposits in the landslide body. Therefore, the accumulation of landslides is the main ore-forming mechanism of oxidized orebodies. Primary ore mixed with surrounding rock during landslide causes ore depletion. However, the mixed ore fractures and expands at the same time to increase its porosity and permeability, and gold-bearing arsenic minerals can be partially decomposed under epigenetic environment to become easy Oxygenated ore dressing, in-depth study of the oxidation mechanism of landslide accumulation process is conducive to improving the utilization of gold resources and geology of this type of mineral exploration.
