| 摘 要： | 利用摩洛哥苏斯—马萨—德拉地区内的地球化学信息,采用绘制三元图的方法推测地质体覆盖情况、元素组合异常强弱、预测矿产类型。该方法是在筛选相关性强的造岩(成矿)元素基础之上,利用三个单元的元素含量数据成图,依据三元图色标推断地质体和对成矿元素组合异常作出评价。结果显示三元图方法划分的地质体,圈定成矿元素组合异常、预测多金属矿产分布效果较好,证明该方法能反映地球化学分区特征。

| Abstract: | Using geochemical information obtained in Sous-Massa-Dela area of Morocco, the authors adopted the method for drawing the ternary diagram to infer the covering situation of the geological body as well as the intensity of element composite anomaly and predict types of mineral resources. Based on sieving rock-forming elements with strong correlation, this method utilizes the element content da-ta of three units to realize mapping and deduces the geological body and evaluates the composite anomaly of metallogenic elements based on the color chart of the ternary diagram. The results obtained by the authors show that the ternary diagram method is quite effective in dividing the geological body, delineating the distribution of composite anomaly of metallogenic elements and predicting distribution of polymetallic mineral resources. It is proved that the method can reflect the characteristics of geological division. |
