Hydrological method for quickly positioning sandstone type uranium mineralization prospective area in grassland coverage area

Abstract

The invention belongs to the technical field of uranium mineralization prediction, and particularly relates to a hydrological method for quickly positioning a sandstone type uranium mineralization prospective area in a grassland coverage area. The hydrological method comprises the following steps: investigating and sampling a herdsmen well to determine aquifer distribution, and analyzing a water sample to obtain uranium mineralization information and uranium mineralization information; defining an underwater uranium abnormal region, an underwater uranium radium balance coefficient Kp abnormal region, an underwater Po210 abnormal region, an underwater water chemical abnormal region, an underwater oxidation-reduction capability Eh abnormal region and an underwater mineralization degree abnormal region, including determining an underwater uranium mineralization abnormal region and a favorable uranium mineralization region, and determining a uranium mineralization prospective region through the underwater uranium mineralization abnormal region and the favorable uranium mineralization region. According to the method, on one hand, manpower, financial resources and material resources required by exploration and research are avoided; in addition, the method is easy to operate and high in practicability, particularly for uranium ore prospecting in grassland coverage areas of Inner Mongolia, Sinkiang and the like in China, economy is good, and implementation is fast.

Description

technical field [0001] The invention belongs to the technical field of uranium mineralization prediction, and in particular relates to a hydrological method for quickly locating sandstone-type uranium mineralization prospect areas in grassland coverage areas. Background technique [0002] With the continuous improvement of sandstone-type uranium mine exploration work, the surface mines and outcrop mines have been found, and currently the main search is for buried mines and concealed mines in the overburden area. In Inner Mongolia, Xinjiang and other vast sedimentary basins covered by grasslands, thick layers of soil are developed on the surface, and the covering thickness is often relatively large, ranging from tens of meters to hundreds of meters, covering up the uranium mineralization environment and prospecting information , Bring great difficulty to uranium ore prospecting. The traditional ore prospecting method in grassland covered areas is to initially detect the ore-...

In Inner Mongolia, Xinjiang and other vast sedimentary basins covered by grasslands, thick layers of soil are developed on the surface, and the covering thickness is often relatively large, ranging from tens of meters to hundreds of meters, covering up the uranium mineralization environment and prospecting information , bringing great difficulty to uranium ore prospecting

The traditional ore prospecting method in grassland covered areas is to initially detect the ore-forming environment by seismic and electromagnetic methods, and to find out the ore-forming environment and ore-forming information by extensive drilling. The overall period is long and the investment is large. the destruction of
