| Abstract: | An analysis of the distribution of the Late Paleozoic strata on Northeast China and adjacent region reveals a zonal pattern
of the distribution around the core of the Jiamusi-Mongolia Block. The main part of Late Paleozoic marine strata in this area
is considered the continental margin deposits of the Jiamusi-Mongolia Block by analyzing the stratigraphic contact relationship,
lithofacies, etc. The results are exhibited in a series of tectonic paleogeographic maps. This presents an important proof
for the foundation of the Jiamusi-Mongolia Block, and confines the forming time of Jiamusi-Mongolia Block to the Late Silurian.
