近十余年来地球化学找矿方法在世界許多国家得到了广泛的应用。其原因在于容易被发現的矿床的数量日益减少,急需这种新的方法来解决当前迫切的找矿任务,特别是找寻不出露地表的矿床。地球化学找矿方法目前約可分为四类,即岩石化学方法、水化学方法、生物化学方法和气体化学方法。岩石化学方法按采样对象不同,又可分为金属量測量法(采取現代坡积残积层的样品)、分散流法(采取現代水系冲积层的样品)及原生分散暈法
In recent ten years, the geochemical prospecting method has been widely used in many countries in the world. The reason is that the number of easily found deposits is decreasing day by day, and this new method is urgently needed to solve the current urgent prospecting task, especially to find deposits that do not reveal the surface. Geochemical prospecting methods currently can be divided into four categories, namely, rock chemistry, water chemistry, biochemical methods and gas chemistry. The petrochemical method can be divided into the metal amount measurement method (take the sample of the modern slope plot residual layer), the dispersion flow method (take the samples of the modern aquifer alluvium layer) and the primary dispersion halo method
