西安白钨矿床中的矿体主要赋存于元古界板溪群马底驿组中下部碳酸盐岩层中,矿体的分布和产状受地层、断裂构造和岩性控制,具明显的层控特征。同位素地质学和地球化学的研究证明:
The ore bodies in the Xi’an scheelite deposit mainly occur in the middle and lower carbonate rocks of the Matianyi Formation of the Banxu Group in the Proterozoic. The distribution and occurrence of ore bodies are controlled by the strata, faults and lithology. Layer control features. Isotope geology and geochemistry research shows that:
