摘要

The Agnigundala base metal belt (16°05'–16°20'N lat. and 79°35'–79°50'N long.), traced over a cumulative strike length of about 6 km, is located near Vinukonda, Guntur district in the northeastern part of the Cuddapah Basin (Figure 1 a) and constitutes one of the prominent base metal deposits in India. About thirty copper– lead–zinc occurrences are localized within this belt, with Bandalamottu, Nallakonda and Dhukonda constituting the main deposits. Though Cuddapah Basin contains vast resources of mineral wealth, isotopic studies on mineralization are scanty, except for the S-isotopic study of the Mangampeta baryte deposit and Pb, Sr and Nd isotopic studies of uranium-mineralized stromatolitic Vempally dolomites. Variation in isotopic composition of sulphides has an important bearing on type of mineralization. We present here S-isotopic data on carbonate-hosted lead mineralization of the Bandalamottu area, Guntur district, Andhra Pradesh and discuss the role of sulphur in the process of Pb-mineralization.
