根据小秦岭石英脉型金矿床石英脉的空间分布、结构构造特征和矿床形成的温压条件，提出小秦岭金矿的液压致裂定位机制。在成矿期间容矿空间的扩张与矿液的充填是同时的，容矿空间的形成是矿液液压致裂作用的结果。在成矿过程中，随着矿液自身压力的逐渐增加，当达到或超过围岩静压力时，围岩便产生张裂，矿液随之充填沉淀。照此反复进行，矿脉逐渐增生，最终形成不同期次、不同矿化阶段的脉状金矿床。
According to the spatial distribution of quartz veins and structural features of the quartz vein-type gold deposits in Xiaoqinling, and the temperature and pressure conditions for the formation of the deposits, the hydraulic fracturing mechanism of the Xiaoqinling gold deposit is proposed. During the ore-forming period, the expansion of the ore-hosting space is at the same time as the filling of the ore fluid. The formation of the ore-holding space is the result of the hydraulic fracturing of the ore fluid. In the process of mineralization, with the gradual increase of the pressure of the ore liquid, when the static pressure of the surrounding rock is reached or exceeded, the surrounding rock will be cracked and the mineral liquid will fill in the sediment. As the repeated, veins gradually proliferated, and eventually formed different periods, different stages of mineralization vein gold deposits.
