600 million light-years ago, Taihang Mountain area was an area of Wang Yang. After that, it experienced frequent crustal theme activities, road surface ups and downs, and sea surface advances and retreats. At the time of regression, swamps were widely distributed, the climate was warm and humid, and dense forests were growing, thus producing rich and colorful coal energy in Taihang Mountain area. Later, the theme activity of the earth's crust made Taihang Mountain protrude slowly. Later, it broke up with the North China Plain, resulting in steep terrain in the eastern part of the Taihang area and slow terrain in the central and western parts.
In about 240 1 100 million years, it gradually rose sharply and gradually formed. As early as 2.8 billion light years ago, Taihang Mountain area was swallowed up by the sea, and huge thick clastic rocks, iron-bearing siliceous rocks and sulfide strata were accumulated. Due to the hazards of Wutai Fitness Exercise and Lvliang Fitness Exercise, the strata with a long history in this area are widely wrinkled and moldy, accompanied by the rupture and intrusion of quartzite jade veins. Up to18 billion light years ago, a mixed rock layer based on crystal was produced.
Since the fitness exercise in Lvliang 654.38+08 billion light years ago, the crust in the region has entered different stages of ups and downs, which has caused the sea surface to fluctuate repeatedly, forming the Mesoproterozoic tatami platform accumulation cover and its overlying Paleozoic Cambrian, Ordovician, Carboniferous and Permian strata. The Ordovician and Permian are coal-bearing strata. Yanshan Fitness Movement, which originated in Triassic, slowly produced the Taihang Mountain Neocathaysian Fold Belt and developed the deep fault zone in front of Taihang Mountain.
The Himalayan fitness exercise produced in Cenozoic era made Taihang Mountain rise obviously, and the North China Plain in front of the mountain moved down relatively. After millions of years of tempering, Taihang Mountain was finally created.
Taihang Mountain should also master the following aspects.

The geological environment basement of Taihang Mountain is a small compound monoclinal fold. The eastern part is fault block structure, and the typical alluvial fan and its alluvial plain area grow and develop in front of the mountain. Taihang Mountain is an important geographical dividing line in eastern China. Taihang Mountain is the natural dividing line between Loess Plateau and North China Plain.
