Abstract

The Eastern Dharwar Craton (EDC) in southern India frequently features lamprophyre dykes, with the present study identifying two new dykes near South of Garla village. Petrographic and geochemical analyses were conducted on these dykes, which intrude the granitoids of the Peninsular Gneissic Complex-II (PGC-II) within the EDC. Petrographic examination revealed a panidiomorphic texture, with clinopyroxen, biotite, and amphibole as phenocrysts, and k-feldspar, plagioclase feldspar, and biotite in the groundmass. The lamprophyre's composition is characterized by varying levels of SiO2, Fe2O3, MgO, CaO, K2O, TiO2, and Al2O3, alongside elevated concentrations of trace elements such as Ba, Sr, Ni, Zr, V, and Cr. The lamprophyre is classified as minette of the Calc Alkaline Group based on its geochemical and petrological attributes.
