四、热液成矿系统中地下水的运动和排泄地下水热液的运动和排泄特征对热浓成矿系统的形成和分布具有重要意义.不同成因和在不同埋藏集聚条件下,地下水的运动和排泄具有不同特征.渗入水在岩石空隙中的渗流是在重力作用下发生的;其运动特征主要取决于补给区和排泄区的位置(地形高差及其间距)所决定的水静压力梯度.在不同深度上水交替强度不同.沉积成因水在初始迁移(压榨)阶段,水动力特征主要取决于上覆岩系重量和自重影响下沉积物的压密作用.由于压密层土颗粒骨架和其孔隙中的水共同承受上覆层的压力,水就产生了层状
4. Movement and excretion of groundwater in hydrothermal ore-forming system The movement and excretion of groundwater hydrothermal fluids are of great significance to the formation and distribution of the hot mineralization system.Different causes and movement and excretion of groundwater under different burial conditions With different characteristics.The infiltration of infiltrated water in the rock void occurs under the action of gravity, and its motion characteristics depend mainly on the hydrostatic pressure gradient determined by the location of the recharge and discharge zones (terrain elevation and its spacing). The water alternation intensity is different at different depths.Due to the origin of water during the initial migration (crushing) stage, the hydrodynamic characteristics mainly depend on the compaction of the sediments under the influence of the weight and gravity of the overlying strata. The water in the pore co-withstands the pressure of the overburden and the water creates a layer
