SUMMARY
Charactersitics of the Middle-Late Paleozoic rock facies and paleogeography in the Hạ Lang Region, Cao Bằng Province

Stratigraphic
units have been formed in a specific condition and geological history. The
sedimentary properties such as grain size, roundness, chemical composition,
especially the presence of biofossil will significantly help geoscientists
reconstruct the environmental condition of an area on the Earth surface. The
Hạ Lang Area, where was deposited by the Middle-Upper Paleozoic
sedimentary formations, which were formed during the Early - Lare Devonian and they are typically
characterized by sedimentary composition and fossil. These are the basis for
interpretation of the paleogeography of these formations.
