Main geo-heritage types of Jiuhuashan geopark

2018-05-31

The geoheritages of the Jiuhuashan Geopark are abundant and of special significance. They could be classified into 4 categories (Table1): (1) the geologic profiles like as the sima magmatic profile of the Qingyang rock body, the sial magmatic profile of Jiuhuashan rock body, the dykes profile of the late Ke Village dyke swarms created by collision of intracontinental tectonic plates; (2) geological structure heritages mainly consisting of the strike-slip Jiuhuashan Fault and small-medium joint structures; (3) geomorphic landscapes that are composed of huge fault-block granite landform formed by fault structure, combination of mountain-hill-basincirque and U-shaped valley of Quaternary glacier relics, and fluvial landscapes; (4) Water landscapes, such as lake, waterfall, spring, and scenic river sections.
