河南汝州—宝丰—鲁山地区铝土矿Li、Ti、Ga、Zr、Nb和LREE的矿化特征
|
摘要
文章对河南省汝州—宝丰—鲁山地区铝土矿进行了稀有金属、稀土元素和稀散元素("三稀")矿化调查,发现了Li、Ti、Ga、Zr、Nb和LREE矿化信息,并显示了V、Rb和Th的异常富集信息,这为该地区铝土矿—"三稀"的综合勘查开发提供了参考。该地区铝土矿样品中的Al_2O_3与TiO_2、Zr和Nb_2O_5呈正相关关系,与Ga含量整体上呈负相关关系;铝土矿的元素含量存在一定的空间分布规律,南部张店—张八桥成矿带的Al_2O_3、Zr含量及A/S比值较高,中部观音堂—大营成矿带的TiO_2、La和Ce含量较高。综上认为,南部张店—张八桥成矿带是汝州—宝丰—鲁山地区铝土矿成矿区内铝土矿—"三稀"资源潜力较大的区段。
The mineralization of Li,Ti,Ga,Zr,Nb and LREE was found during the geological investigation of rare metal elements,rare earth elements and rare dispersed elements in bauxite deposit area in Ruzhou-Baofeng-Lushan area.The abnormal enrichment anomalies of V,Rb and Th were outlined,which provided reference for prospecting and exploitation of rare metal elements,rare earth elements and rare dispersed elements.There is positive correlation between Al_2O_3 and TiO_2,Zr and Nb_2O_5,and negative correlation between Al_2O_3 and Ga concentration in bauxite deposit. There is spatial distribution regulity of element concentration in bauxite deposit,i.e.,the contents of Al_2O_3 and Zr,A/S ratio are higher in Zhangdian-Zhangbaqiao area in the southern deposit,the TiO_2,La and Ce contents are higher in Guanyintang-Daying area in the central part. Based on above-mentioned information,it is predicated that there is prospecting potential for rare metal elements,rare earth elements and rare dispersed elements in the Zhangdian-Zhangbaqiao metallogenic belt in the southern Ruzhou-Baofeng-Lushan bauxite metallogenic area.
