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。根据重矿物对比研究和地貌分析，阐明了泰沂隆起区太古界和元古界的高氟古老岩系为该区土壤沉积物源，黄河多次泛滥堆积（粘土矿物对氟的吸附）对土壤氟起了叠加富集的作用。研究揭示该区土壤水溶氟较高，经降水淋滤和浸取作用氟转入地下水，并在凹陷区或河间洼地中聚集，水体停泄、蒸发浓缩形成高氟地下水区。
Through the geochemical profile of fluorite in the Archean-Cenozoic and the abundance of fluorine in the magmatic rocks and soils in this area, the geochemical zone with high fluorine content is demonstrated. According to the comparative study of heavy minerals and the analysis of geomorphology, it is clarified that the high-fluorine ancient rock series of the Archean and Proterozoic in the Taiyi uplift are the source of sediments of the area, the frequent flooding and accumulation of the Yellow River (adsorption of fluorine by clay minerals) Fluorine plays a role of superposition and enrichment. The study revealed that the soil had a high fluoride content in the water, leached by precipitation and leached into the groundwater, and accumulated in the depression or inter-river depressions. The water body stopped its discharge and concentrated by evaporation to form a high-fluoride groundwater zone.
