摘要
陕蒙交界地区基岩均具强风化,由此造成当地环境恶化、下游地区生态破坏和灾害积累。其形成机理应与岩石本身的物质组成、自然地理环境、地质构造状况、水文地质条件及其物理化学条件有关。而南部地区,由于上述诸因素的差别,基岩风化微弱。
The basement rocks occurring in between Shaanxi and the Inner Mongolia had been extremely weathered, which has resulted in deterioration of the local environment, environment damaged and accumulation of natural hazards in the catchment areas. The genetic formation should be related to the composition the rocks, geographical enviornment, geological structures, hydrogeological, physical and chemical conditions. The basement rocks in the southern region have been weathered weakly due to the discrepancy of the factors mentiioned above.
