Low temperature hydrothermal uranium deposit, hosted in granite within a fracture zone.

This deposit has been mined out.
(302 deposit?)

Notably, the vertical distribution of uranium mineralization spans a considerable range, extending from the surface (elevation 500 m) to depths (elevation −900 m). The uranium ores can be classified into two types: (1) reddened alteration ore, characterized by iron oxides/hydroxides formed during fluid-granite interactions, with a mineral assemblage of pitchblende, coffinite, brannerite, reddish microcrystalline quartz, hematite and chlorite; (2) gray-black ore, composed of pitchblende, coffinite, gray-black microcrystalline quartz, pyrite, fluorite, and calcite. Hydrothermal alteration of the Mianhuakeng uranium deposit can be divided into two distinct types: firstly high temperature alterations and secondly medium to low-temperature alterations. The high temperature alteration type mainly includes albitization and potassic feldspathization, while the medium to low-temperature alteration mainly involves fluoritization, silicification, hematization, sericitization, chloritization, pyritization and carbonatation. In the medium to low-temperature alterations, there is a close relationship between silicification, hematization, pyritization as well as fluoritization and uranium mineralization. Four episodes of uranium metallogenic activities have been dated: approximately 120 Ma, 102 Ma, 92–90 Ma, and 68–60 Ma.

The primary types of mineralization in the deposit consist of silicification zone-type and fractured rock-type mineralization, with fewer instances of intersection-type uranium mineralization occurring at the junctions of mafic dykes and fault zones.
