Tianshan, with its mighty majesty, became a symbol of Xinjiang. In order to meet the thirtieth International Geological Congress held in our country in 1996, the Ministry of Geology and Mineral Resources has approved the “Non-Smith Stratigraphy and Paleo-Sea Biology Experimental Research”. The author chose the Tianshan area as the research target area and carried out a field investigation for more than a month in August-September 1994. Tracing the ancient ocean shell The Tianshan Mountains are made up of four arc-shaped mountains that form a mountain knot of more than five kilometers at the intersection of the mountains.
