作砂矿床预测、研究砂矿床——独立的成矿体——地球化学晕、它们形成的动力学及共同基岩矿源晕的关系有重大意义,而在普查与古河床及构造台阶带有关的埋藏砂矿床时,地球化学晕可成为关键性的找矿标志. 早先进行的研究业已查明,砂矿晕同供给源有着不可分割的联系,它是基岩矿体地球化学分带的间接反映;划分了相的、动力学的及构造的地球化学障,它们改变了有用组分
It is of great significance to make a prediction of the sand deposit, study the relationship between the sand deposit, the independent ore-forming body, the geochemical halo, their formation kinetics and the halo of the common bedrock mine source. However, Geochemical halo can be a key ore-prospecting marker when burial sand deposits, and earlier studies have identified that the sandstone halo is inextricably linked to the source of supply and is an indirect reflection of the geochemical zonality of bedrock orebodies ; The division of facies, kinetic and structural geochemical barriers, which change the useful components
