Abstract

Stratigraphic division also age of the sequence of cherty shale (the Bang Ca Formation) in Bang Ca Townlet, Ly Quoc Commune, Ha Lang District, Cao Bang Province, North Vietnam presently is still a subject for debate: Bourret R. 1922 (Late Devonian), Vasilevskaya A. D. 1965 (Eifelian-Givetian), Pham Dinh Long 1973 (Givetian), Duong Xuan Hao et al. 1973, 1980 (Frasnian); Pham Huy Thong, Nguyen The Dan 1984 (Famennian); Doan Nhat Truong, Ta Hoa Phuong 1999 (Middle-Upper Devonian); Doan Nhat Truong, Ta Hoa Phuong 1999 (Frasnian-Famennian); Tong Dzuy Thanh 2011 (Middle-Upper Devonian). Studying stratigraphic order of Devonian sequence exposed in the Ban Thung-Bang Ca-Lung Thoang section, also based on macro-fossils newly collected from the cherty shale, the Bang Ca Formation is recognized as a lithostratigraphic unit, overlying the Na Quan Formation (D_1-2 nq), and underlying the Toc Ta Formation (D₃-C₁ tt) with total thickness about 200 m. The Frasnian age of the Bang Ca Formation is based on macrofossil asemblages Atrypa (Desquamatia) cf. zonataeformis, Spinatrypa sp., Monelasmina sp. (Brachiopoda); Glyptohallicardia cf. ferruginea (Bivalvia), Manticoceras sp. (Ammonoidea); Homoctenus sp., Viriatellina sp., Striatostyliolina sp., Styliolina sp. and conodont Ozarkodina sp.
