The Shanwang National Geology Park (simplified Chinese: 山旺国家地质公园; traditional Chinese: 山旺國家地質公園; pinyin: Shānwàng Guójiā Dìzhì Gōngyuán) is located in central Shandong province, People's Republic of China, about 22 kilometres (14 mi) from Linqu County. It has an area of about 13 square kilometres (5.0 sq mi). The Park is well known for the fossil bearing Shanwang Formation diatomitic deposits, one of only a few such deposits in China. It is also well known for its volcanic topography. The Shanwang Formation dates to about 18-11 million years ago, from the Langhian to the Serravallian.
