Abstract
In recent years, mineral resources near the surface are becoming scarce, causing focused mineral exploration on concealed deposits in covered terrains. In northern China, covered terrains are widespread and conceal bedrock sequences and mineralization. These represent geochemical challenges for mineral exploration in China. As a deep-penetrating geochemical technology that can reflect the information of deep anomalies, the fine-grained soil prospecting method has achieved ideal test results in arid Gobi Desert covered terrain, semi-arid grassland covered terrain, and alluvium soil covered terrain of northern China. The anomaly range indicated by the fine-grained soil prospecting method is very good with the known ore body location. The corresponding relationship can effectively indicate deep ore bodies and delineate anomalies in unknown areas. Overall, the fine-grained soil prospecting method can be applied to geochemical prospecting and exploration in covered terrains.
Highlights
As mineral resources near the surface are becoming scarce, deep-penetrating geochemistry for finding concealed deposits has attracted significant attention and obtained favorable results [1,2,3]
With the continuous improvement of the degree of mineral exploration work, the possibility of discovering new deposits in outcropping areas has become less and the search for concealed mines in the covered terrains has become a focus of attention

Summary
As mineral resources near the surface are becoming scarce, deep-penetrating geochemistry for finding concealed deposits has attracted significant attention and obtained favorable results [1,2,3]. As the soil particle size becomes smaller, the specific surface area of iron-manganese oxides increases exponentially, and its ability to adsorb active metal elements increases. Compared with other deep-penetrating geochemical methods, the fine-grained soil prospecting method is simpler to operate in field sampling and laboratory analysis, making it easier to master and promote [6,7]. Whether it is for the general survey and detailed investigation of concealed mines on the deposit scale, or the rapid geochemical survey of the coverage area, the fine-grained soil prospecting method is highly suitable [4,7]
