Ring-morphostructures of the Amur-Songhua-Huanghe lineament (eastern margin of Asia)

The “ring-morphostructures” (RM) are the object of this study. They are one of the most significant element of lineament’s structure and unknown for the majority of investigations. RM are numerous to lineament’s zone: they have-different size (from 10–20 km to 500–800km in diameter), structure, age, geological history and have been divided into several classes on the most important signs. They have a spatial-genetic connection Amur-Songhua-Huanghe lineament (ASHL) and had been developed simultaneously with it. The RM exerted an essential influence on the geologic-geomorphological structure, evolution and geodynamics of lineament. The main factor of evolution of lineament is a long geological process of extension of the earth’s crust which is a result of the expanding earth.
