More than five billion tons of karstic bauxites were formed in the North China Craton (NCC) during Late Carboniferous period. Compared to bauxite ore, genesis entire aluminous-bearing strata has received less attention. In this study, we conducted geological, mineralogical, and geochemical analyses on core samples from located Xingxian area, situated within northern NCC, aiming elucidate genetic process these formations. The consist a layer (diaspore–anatase–kaolinite–florencite) sandwiched between upper sandy claystone horizon (kaolinite–illite–quartz) lower berthierine-bearing (berthierine–diaspore–hematite–goethite). Based continental crust-normalized patterns rare earth elements yttrium (REY), immobile trace element ratios, mineral inheritance diagrams, previous findings, it is suggested that was weathered impure limestone at bottom, whereas mainly originated intermediate-felsic igneous rocks margin granite Qinling Orogenic Belt, aluminosilicate surrounding paleo-uplifts. During early diagenetic stage, berthierine transformed under alkaline reducing conditions iron-rich clays (composed clay minerals, ferric etc.) acidic oxidizing underlying limestone. coexistence with low-temperature stability diaspore observed claystone, which precludes high-temperature origin strata. Moreover, characterized by small crystal size usually poorly crystallized, suggesting supergene precipitation-diagenesis origin. paragenetic minerals assemblages (e.g., diaspore, berthierine, goethite, hematite, suggest primarily transition zone nearer phreatic environment. Large-scale volcanism warm, humid climatic accelerated decomposition allochthonous weathering materials, resulting downward migration metal ions. These ions then precipitated weakly environment, giving rise form ore dominated anatase, REY minerals.

Critical metals in coal-bearing strata have recently emerged as a frontier hotspot both coal geology and ore deposit research. In the Upper Carboniferous “Si–Al–Fe” (Benxi Formation) of North China Craton (NCC), several critical metals, including Li, Ga, Sc, V, rare earth elements Y (REY or REE + Y), been discovered, with notable mineralization anomalies observed across northern, central, southern Shanxi Province. However, despite widespread occurrence outcrops northeastern Qinshui Basin eastern Shanxi, there has no prior report on metal content this region. Traditionally, regarded primary source clastic material for surrounding seams Carboniferous–Permian Taiyuan Formations, which are known to display (e.g., Li Ga). Given these observations, it is hypothesized that may also contain mineralization. To evaluate hypothesis, new outcrop samples from Benxi Formation Yangquan area were collected. Detailed studies enrichment assessed using petrographic mineralogy (XRD, X-ray diffractometer), geochemistry (XRF, fluorescence spectrometer, ICP-MS, inductively coupled plasma mass spectrometer). The results indicate siliceous, ferruginous, aluminous rocks within study exhibit varying degrees mineralization, mainly consisting REY, minor associated Nb, Zr, Ga. Al2O3/TiO2, Nb/Y vs. Zr/TiO2, Nb/Yb Al2O3/TiO2 diagrams suggest metal-enriched layers likely mixed origin, comprising intermediate–felsic magmatic metamorphic derived NCC, well alkaline volcaniclastics Tarim Large Igneous Province (TLIP). Furthermore, combined geochemical parameters, such CIA (chemical index alteration), Sr/Cu Ga/Rb, Th/U, Ni/Co V/(V Ni), deposited under warm-to-hot, humid climate conditions, suboxic-to-anoxic environments. Additionally, an economic evaluation suggests hold considerable potential resource industrial extraction
