Balouhe Fm
Type Locality and Naming
Local deposit. The type section is originally unassigned. BGMRS(Shandong)P (1996) assigned a lectostratotype for this formation, which is located at east side of the Balouhe River (E117°28′, N36°43′), northwest of the Dazhan Reservior, Zaoyuan town, Zhangqiu City, Shandong Province. It was named by Jiang and Wu (1978).
Lithology and Thickness
It is characterized by greyish-white massive limestones with conglomerates, white lumpy marlstones, yellowish-white calcareous mudstones, greyish-yellow calcareous-cemented conglomerates, and deep-yellow loose conglomerates. Its top limestones contain fossil reptiles, mammals, and mollusks. Its thickness is less than 20 m.
Relationships and Distribution
Lower contact
In the type section, the Balouhe Fm unconformably contacts with the underlying Triassic Liujiagou Fm of the Shiqianfeng Gr (BGMRSDP, 1996). Regionally, the Wangshi Gr would be underlying?
Upper contact
In the type section, the Balouhe Fm is unconformably overlain by the Quaternary Dazhan Fm.
Regional extent
In other area, it unconformably contacts with the overlain Pliocene red clay or Quaternary loess and the underlying Permian sandstones. This formation is restricted in the Balou River drainage, Zhangqiu City, Shandong Province.
