As a part of National Geochemical Mapping (NGCM) programme of GSI, regional geochemical mapping was carried out for an area of 705 sq km in parts of Katni, Panna and Satna districts of Madhya Pradesh covering toposheet number 64A/05 bounded by latitudes N23°45′00″ to N24°00′00″ and longitudes E80°15′00″ to E80°30′00″. Chemical analyses of 182 composite stream/slope sediments samples were carried out and baseline geochemical maps of oxides and elements were prepared. Data analyses has led to significant conclusions on environment hazard due to metal contamination and possible mineral potential due to REE enrichment. Study of the spatial distribution of individual variables showed Cr and Co have values higher than the permissible level in dry soils in some parts of the area which requires investigation by concerned agencies. Some samples over the laterites show higher than threshold values of REEs which are much higher than their crustal abundance. Factor analyses on the geochemical data with 46 oxides and elements has led to the identification of five factors accounting for 84% of the total variance of the data set and describing five physico-chemical processes controlling the spatial geochemical variation. The analyses points to the enrichment of the REEs in the lateritisation process. The laterites covering 171 sq km of the area need to be considered for investigation of REE potential.

作为GSI国家地球化学测绘（NGCM）计划的一部分，在中央邦卡特尼，潘纳和萨特纳地区的部分地区进行了705平方公里的区域地球化学测绘，地形图编号为64A / 05，其纬度为N23° 45'00”至N24°00'00”，经度E80°15'00”至E80°30'00”。对182个复合流/斜坡沉积物样品进行了化学分析，并制备了氧化物和元素的基线地球化学图。数据分析已得出有关金属污染造成的环境危害以及稀土元素富集可能产生的矿物质潜力的重要结论。对单个变量的空间分布的研究表明，Cr和Co的值高于该地区某些地区旱地中允许的水平，需要相关机构进行调查。红土带上的一些样品显示出的稀土元素的阈值高于其地壳丰度的阈值。利用46种氧化物和元素对地球化学数据进行因子分析后，已确定了占数据集总方差84％的五个因子，并描述了控制空间地球化学变化的五个物理化学过程。分析指出，稀土元素在红化过程中的富集。研究REE潜力需要考虑面积为171平方公里的红土。利用46种氧化物和元素对地球化学数据进行因子分析后，已确定了占数据集总方差84％的五个因子，并描述了控制空间地球化学变化的五个物理化学过程。分析指出，稀土元素在红化过程中的富集。研究REE潜力需要考虑面积为171平方公里的红土。利用46种氧化物和元素对地球化学数据进行因子分析后，已确定了占数据集总方差84％的五个因子，并描述了控制空间地球化学变化的五个物理化学过程。分析指出，稀土元素在红化过程中的富集。研究REE潜力需要考虑面积为171平方公里的红土。
