Geopark introduction: The ancient deep metamorphic rocks in the Bailudong area were later torn and separated by detachment faults to the shallow part of the earth's crust to form the core of the metamorphic box complex, which is 70 years old in the eastern part of the Yangtze Plate. The only ancient rock formation exposed in 10,000 square kilometers. Therefore, Bailu Cave is also a geopark with great scientific research value.
