Occurrence Sentence Text Source
Chengjiang is an underdeveloped city having rich phosphate deposits above and below the formation holding the lagerstxc3xa4tte.
They have been exploited in part through efforts that began at about the same time that Hou Xian-guang discovered the deposits that bear these exceptional fossils, with phosphate mining bringing in some 2/3 of the city's revenue in 2003.
Efforts were made to close the region to mining in a bid to support the city's bid for listing as a World Heritage Site, given the scientific significance of the fossils.
The finances of the Chengjiang Fossil Site come largely from national sources and are supplemented by smaller contributions at the City and County levels.
