CHARACTERISTICS AND DIVISION OF THE NANHAU SYSTEM IN LIAONING, CHINA

The Nanhau System, previously known as Hanhua Ice Age, is characterized by the broad occurrence of glacial actions. However, the glacial sedimentation has not found yet in the Nanhua System in Liaoning Province. In contrast, numerous macro algae fossils are developed in the Nanhua System in Liaoning, showing a warm and humid condition of ancient climate. The Pre-Cambrian glacial activities in the rest of the world occurred all in the regions with low paleolatitude. According to the paleomagnetic data, the Nanhua System in Liaoning is distributed in the areas with medium and high paleolatitude. Therefore, the Nanhua System in Liaoning would not produce glacial rock. The "warm type Nanhua System" is developed in Liaoning. This conclusion will provide a new idea for the division and correlation of the Nanhua System in China.
