Da Youkeng Wenquan — 'Great Oil Pit Hot Spring' — is a geothermal spring in China, its intriguing name referencing a 'great oil pit' — perhaps a large, deep depression filled with naturally warm, mineral-rich water whose surface oil slick or viscous appearance earned it this evocative petroleum-related designation. Springs associated with oil-like surface films — caused by hydrocarbon seeps, sulphur compounds, or mineral precipitates — have historically attracted both curiosity and therapeutic use, their unusual appearance interpreted as evidence of exceptional mineral richness. The spring provides naturally geothermally heated, mineralised water in a distinctive geological setting.
