通过该区太古界一新生界氟的地层地球化学剖面及岩浆岩和土壤中氟的丰度的研究，论证了该区为一高氟的地球化学区。

This region is demonstrated as a geochemical region with high fluorine through studies on the fluorine contents of soils, magmatic rocks and the Archean?Cenozoic strata geochemical profile.

这种含油气性预测方法是建立在综合地层、构造、岩性-岩相、地球化学和本文地质指标和对每种指标进行评价的基础上的。

This method is based on the comprehensive indexes, such as strata, structure, lithology-lithofacies, geochemistry and hydrogeology, and evaluations of these indexes.
