Palnad Basin is the storehouse of limestone which is equivalent to the Narji limestones of the Kurnool Basin. Krishna stream cut over the Palnad Basin generally is EW course and limestones uncovered on either side. Palnad Basin covers parts of Nalgonda district of Telangana and the Krishna & Guntur districts of Andhra Pradesh. The Palnad limestones are lithologically similar to the Narji limestones of the Kurnool basin (Madhusudhan Rao, 1964). (Madhusudhan Rao, 1964). They are well exposed on either side of the Krishna River to the North of river Krishna in Nalgonda, to the South of river Krishna in Guntur district of Andhra Pradesh, and to the East of river Krishna in Krishna district of Andhra Pradesh. Nalgonda district is located in the southern part of Telangana state in India and encompasses an area of roughly 14,240 square kilometers. The district has abundant natural resources, including limestone, and quartz. The geology of Nalgonda district is diversified, with rocks ranging in age from the Archean to the Quaternary. The district is separated into four major geological units: the Archean Gneissic Complex, the Proterozoic Cuddapah Supergroup, the Mesozoic Deccan Traps, and the Recent Alluvium. Limestones display a considerable range in hue viz., purple, green, pale green, chocolate, buff, dark grey, and light grey. The limestones are fine-grained with shallow dips across the whole basin, but rolling dips are not unusual. Limestone resources evaluated in
