摘要
本文研究了金伯利岩与钾镁煌斑岩所具有的地球化学共性,建立了含金刚石岩石地球化学勘查模型,该模型利用载体岩石及相似岩县有相容和不相容元素异常的性质,可识别偏碱性超基性岩引起的化探组合异常点,并可用于判定异常体的属性。该模型通过一定的对比和实际应用,证明具一定的实用价值。
Based on the similarities of kimberlite and some typical lamproite on ge- ochemical properties,the author presents you quite a few facts on the regular di- stribution and correlated relations of each kind of elements,including petrochemical composition data,rare earth element data and trace element data. By using many data and calculating cross correlation coefficient,a geochemical exploration model on primary diamond deposit(carrier rock)has been set up.Because the diamond-car- rier rock and similar rock all have compatible elements and inconpatible elements anomaly,the model has been designed to recognize multiple anomalies of alkalic ul- trabasic rock in geochemical exploration and can be applied to the determination of anomaly property.
