Abstract

The geochemical compositions of gneissic rock samples from the Bundelkhand Craton were studied in order to determine their provenance, the nature of original sediments, and their tectonic setting. These rocks have an abundance of Rb, Ba, La, Ce, and Gd and depletion of Mo, Ho, Tm, Nb, Ta, Sr, Hf, and Ti. A negative anomaly of Nb and Ti suggests a subduction-related environment. The discrimination diagram of log (Fe2O3/K2O) vs log (SiO2/Al2O3) shows that the parental rock of the gneissic rocks is shale. The P2O5/TiO2 vs MgO/CaO plot indicates the recycled sedimentary origin of the rocks. The SiO2 vs log (Na2O/K2O) diagram suggests that the gneissic rocks were deposited in the active continental margin setting. According to tectonic discrimination diagrams with a discrimination function and a binary plot of TiO2 against Zr, the gneissic rocks were derived from felsic igneous rocks. The trace element plots (Th/Nb)N vs (Y/Nb)N and Nb/Zr vs Zr show that gneissic rocks were deposited in an active convergent margin from a felsic igneous source, then transported and metamorphosed.
