Geochemistry data of trachyandesite of Ulindakonda vent agglomerate of Gadwal greenstone belt of eastern Dharwar Craton, India.

ABSTRACT: Ulindakonda vent agglomerate of Neo-archean Gadwal Greenstone Belt in the Eastern Dharwar Craton (EDC), is located partly in the Kurnool district of Andhra Pradesh and partly in Jogulamba Gadwal district of Telangana state, India. Trachyandesite occurs as matrix of the agglomerate and at some places it exhibits massive and interbedded nature with granodiorite that mainly occurs as sub-rounded clasts in the agglomerate reflecting magma mixing and mingling. The rock is dotted with small dark specks of a ferromagnesian mineral which often shows a well-developed cleavage surface. The size of grains ranges from medium to fine-grained. Petrographically it is dominated by feldspars and mafic minerals like hornblende and biotite as accessory minerals and quartz in minor amounts. Further, titanite,
