Uranium deposit, hosted in sandstones belonging to the lower member of the Middle Jurassic Zhiluo Formation. The orebodies are mostly located at or near the contact between gray sandstones and gray-greenish sandstones, owing their colour to the presence of Fe(2+) minerals. The greenish sandstones were reduced by natural gas and miscellaneous organic matter, covering up the lower layers and protecting uranium accumulations from destruction by infiltrating water.
