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.

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。

Existence of special lithologic strata often causes interference with actual reflection of its underlying normal formation on profile.

特殊岩性地层的存在往往会干扰其下伏正常地层在地震剖面上的真实反映。
