Huangao district, Lujing Uranium ore field, Chongyi Co., Ganzhou Prefecture, Jiangxi Province, China

StandardDetailedBy ChemistrySearch GoogleMineral Report for Region

Mesothermal to epithermal uranium deposits (Huanfengling and Gaoxi), hosted by and Indosinian medium- to coarse-grained porphyritic biotite granite of the Lujing batholith (Sanerer pluton) and a Yanshanian fine-grained porphyritic biotite granite stock. The critical processes for the formation of the deposits were deuteric alteration of primary accessory minerals in the granites, and erosion of the granites under a hot, dry palaeoclimate, resulting in the partial liberation of uranium. In the deposit, it occurs as pitchblende along tectonic fractures, interstitially in granular minerals, and as cements of breccias. The host-rock alteration comprises pre-ore alkali-metasomatism and ore-stage hydrothermal chloritization, pyritization, hematitization, silicification, damouritization, and carbonatization.

NOTE: Huangao is an artificial name used by Min et al. (1999), presumably to obscure the true identity of the deposit. It is composed of the first syllables of Huanfengling and Gaoxi, two neighbouring deposits in the Lujing ore field with which the paper actually deals. Occasionally, the term "Huangao district" is arbitrarily used for these two deposits, because they occur close together, separated only by a river.
