The Huiquanpu Formation (simplified Chinese: 灰泉堡组; traditional Chinese: 灰泉堡組; pinyin: Huīquánpù Zǔ) is a geological formation in Shanxi and Hebei provinces, China, whose strata date back to the Late Cretaceous period. It predominantly consists of purple-red mudstone, with subordinate grey-white sandy conglomerates.[2]

Dinosaur remains are among the fossils that have been recovered from the formation.[3]
