Beijing Yanqing Petrified Wood National Geological Park is located on the banks of the Baihe River in the Yanshan County in the northeast of Yanqing County, the summer capital of Beijing. It is 26 kilometers long from east to west and 6-8 kilometers wide from north to south, with a total area of 226km 2. The park is rich in geological relics, beautiful natural landscape, excellent ecological environment, simple folk customs, pleasant climate, immersive and enjoy the scenery, making people nostalgic. Especially the silicified wood group, which is widely distributed, large-scale, produced in situ, and kept intact, is now found with 57 plants, the longest of which is 15 meters, and the largest diameter is 2.5 meters. It is an important evidence for studying the evolution history of the Mesozoic Earth. The park is an ideal place for science research, science education, tourism and vacation, sightseeing and leisure.
Luan Park is distributed along the banks of the Baihe River. Cross three Mesozoic volcanic basins from west to east. The Yanshan Tianchi, formed by the westernmost volcanic basin, crossed the canyon composed of Proterozoic strata to the east, meandered into the Qianjiadian volcanic rock basin, and reached the silicified wood development center. A 55-km-long geography general corridor is formed.
The petrified wood in the Tongliao Geopark was formed in the Mesozoic Jurassic volcanic sedimentary basin between 140 and 180 million years ago. The siliconized wood is hard, clear in texture, and narrow in annual rings. The thickest silicified wood has been excavated up to 2.5 meters in diameter; the longest silicified wood, the trunk stands up to 15 meters in length.
The Shuangdi Kettle (Shuiliandong) scenic spot is distributed in the Proterozoic carbonate formation. Karst caves are developed, spring water trickles all the year round, and water flows down. It is a popular science landscape integrating hydrology, cave sedimentation and karst landforms.
The Small Kunlun landform, composed of quartzite rocks deposited between 1.4 and 1.8 billion years of the Proterozoic Great Wall System, is steep and spectacular.
The redstone bay dome structure displayed on the banks of the Baihe River in Gion is 8 kilometers long from east to west and 3 kilometers wide from north to south. The core is Archean metamorphic rock, and the surrounding area is composed of Proterozoic strata. Later it was cut off by Mesozoic faults, which is a typical dome structure. Can become a good place for popular science teaching.
Cormorants developed from marine sedimentary wave traces and hard structures in the Proterozoic Great Wall carbonate rocks 1.4 billion years ago. Changes in the original depositional environment were reproduced.
Yanshan Tianchi is the highest-altitude water body in Beijing. It is located in the Mesozoic volcanic sedimentary basin. It is surrounded by Chongshan mountains and mountains formed by Proterozoic strata.
