摘　　要：白龙江复式背斜是个古泄水区,区内已知热液矿床(点)的分布与古泄水区(带)的展布相一致,呈现出明显的规律性.古构造和古水动力条件控制了地下水的运动,而古水文(热液)地球化学条件则决定了成矿物质的迁移与沉淀积聚.古水文地质条件是区域热液成矿作用中的重要控矿因素.The Bailongjiang composite anticline is a palaco-drainage area, in which the distribution of known hydrothermal deposits (and ore occurrences) is identical with that of palacodrainage areas (belts) and shows a definite regularity. The palaeostructures and palaeohydrodynamic conditions control the movement of ground Water, while the palaeohydrological (thermal solution) exert a definite influence on the migration and concentration of ore materials. The palaeo-hydrogeological condition is the most important ore-controlling factor in regional hydrothermal minerogenesis.
