Baoligemiao Fm
Type Locality and Naming
The type section is a connection of the Dunda’angger and Bulagesumu sections of the East Ujimqin Banner, Inner Mongolia. It was named by the Mapping Group of the Hohhot Sheet, Inner Mongolian Bureau of Geology in 1961.
Lithology and Thickness
Volcanics. Dominated by continental intermediate volcanic rock, intercalated with pyroclastic rock and terrigenous clastic rock. The main rocks include gray-yellow andesitic lithic-crystal tuff, tuff, andesitic porphyrite, chlorite, epidote amphibolite dacite and andesitic crystal tuff, intercalated with tuffaceous sandstone, slate, siltstone, etc. Containing fossil plants, exposed thickness 7574 m.
Relationships and Distribution
Lower contact
Uncertain: The contact relations with the underlying strata are not clear. Regionally, the next younger unit is the Amushan Fm (but this might be partly coeval)
Upper contact
Uncertain: The contact relations with the overlying strata are not clear. Regionally, the next older unit is the Benbatu Fm
Regional extent
Distributed in Bayan Bulag of the Sonid Left Banner, Bayan Tug of the Abag Banner, Baoligemiao (temple) of the East Ujimqin Banner, and the Horqin Right Wing Front Banner in the eastern part, extending northeast.
GeoJSON
Fossils
Plants: Mainly yielding Angara plants Angaropteridium cardiopteroides, Noeggerathiopsis cf. theoderi, N. annustifolia, etc.; minor Cathaysian plants Asterophyllites sp., Neuropteris sp., Tingia hamaguchii, T. gerardii, Lepidodendron sp., etc., while Tingia is distributed only westernmost of the region.
Age
Depositional setting
It is interpreted as continental volcanic eruptive sediments.
