Dataset on the Geochemistry of soils and their corresponding granitoid plutons of Proterozoic era in Eastern Dharwar Craton, Southern India

This data article provides a detailed dataset on the collected soil samples from the regolith portion of Alkali-Granitoid plutons, those emplaced along the transition zone between Eastern Dharwar Craton and Eastern Ghat Mobile Belt in southern India, due to orogenic collision & later anorogenic rift related tectonism during Proterozoic era. Soils derived from corresponding Paleo to Mesoproterozoic orogenic & anorogenic plutons at Vinukonda, Elechur, Pasupugallu, Podili and Kanigiri majorly showing the enrichment of ∑HREESoil>∑HREERock, the enrichment factor varies from 1.65 to 6.18. Except Vinukonda, Podili, the other soils exhibiting the characteristics of ∑LREESoil>∑LREERock, ∑REESoil>∑REERock, the enrichment factor in soils varies from 1.77 to 3.01 and from 1.9 to 3.05 respectively. Majority of these soils were derived medium to poor grade of weathering and the Chemical Index of Alteration is from 26.30 to 74.92. Although, fractionation of REE in weathered granite/Soil is controlled by the occurrence of REE-bearing minerals and adsorption by weathering products, the ion-adsorption fraction tends to be enriched in HREE relative to source rock.
