| 汝州—宝丰—鲁山成矿带是河南省重要的铝(黏)土成矿带之一，为研究宝丰地区共伴生关键金属矿产的富集规律，本文以韩梁和关岭铝(黏)土矿为研究对象，通过对本地区不同岩性开展系统的采样及测试工作，总结稀土、锂、镓、钛等关键金属的富集规律，并预测该地区的找矿潜力。研究结果表明:韩梁和关岭矿区内含铝岩系轻稀土、锂、镓、钛等元素矿化明显，其中锂在韩梁黏土矿中含量最高，Li2O最高可达 5102.14×10-6。镓和钛在关岭铁质黏土岩中含量较高，分别可达 96.38×10-6、4.31%。轻稀土在黏土矿中含量最高，可达 903.80×10-6。A/S值与 TiO2元素含量大致呈正相关关系，与 Ga和 LREE含量呈负相关关系，与 Li2O不具有明显的相关性。Li2O主要富集于低品位铝土矿及黏土矿，Ga和 LREE主要赋存于黏土矿， TiO2富集于铝土矿中。根据现有评价标准，宝丰地区含铝岩系伴生 Ga和 Li2O潜在资源量分别为 1766 t和 65524 t，建议加大对宝丰地区铝(黏)土矿伴生矿产资源的研究和勘查开发利用。 |

| Ruzhou-Baofeng-Lushan metallogenic belt is one of the important aluminum (clay) metallogenicbelts in Henan Province. In order to study the enrichment of associated key metal minerals in Baofeng area, this pa.per takes Hanliang and Guanling bauxite mines as the research objects, through systematic sampling and testing ofdifferent lithology in this area, the enrichment of key metals such as rare earth elements (LREE), lithium (Li), gal.lium (Ga) and titanium (Ti) are summarized, and the prospecting potential in this area is predicted. The results showthat there are obvious mineralization of LREE, Li, Ga, Ti and other elements in the aluminous rock series in Han.liang and Guanling mining areas, among which the content of lithium is the highest in Hanliang clay mine, and thehighest Li2O can reach 5102.14×10-6. The contents of gallium and titanium in Guanling iron clay rock are relatively high, reaching 96.38×10-6 and 4.31%, respectively. The content of LREE in clay minerals is the highest, reaching 903.80×10-6. A/S value has a positive correlation with the content of TiO2, a negative correlation with the content of Ga and LREE, and no obvious correlation with Li2O. Li2O element is mainly concentrated in low-grade bauxite andclay minerals, Ga and LREE are mainly found in clay minerals, and TiO2 is mainly concentrated in bauxite layers.According to the existing evaluation criteria, the potential resources of associated Ga and Li2O in aluminum-bearingrock series in Baofeng area are 1766 tons and 65524 tons, respectively. It is suggested to increase the research, ex.ploration, development and utilization of associated mineral resources of aluminum (clay) mines in Baofeng area. |
