Abstract:
To decipher both the shallow and deeper features related to Godavari and Kaddam Rivers and the lineaments
present in the eastern margin of Deccan Volcanic Province (DVP) in the Indian Precambrian shield, a total
field ground magnetic survey was carried out around Jagtial town, Karimnagar district, Telangana. The
total field anomaly map based on 653 magnetic observations acquired at 300 m station interval reveals a
combination of NE-SW, NNE-SSW and NW-SE trends, which coincide with the trends in the earlier observed
aeromagnetic anomaly map of the region. The Reduction-to-pole (RTP) map also reveals lineaments that
trend in the NW–SE and NE–SW with varying wavelength and amplitude. From the analysis of magnetic data
we have mapped the north-west extension of the Kinnerasani Godavari Fault (KGF). From our observations
the Kaddam Lineament Zone (KLZ) has been deciphered to be bounded by the Kaddam Lineament to the
north and Kinnerasani Godavari Fault (KGF) to the south forming a small linear basin. Both the Kaddam
Lineament and the KGF appear to be deep seated lineaments/faults. Also, the north-west extension of
charnockites within the KLZ, which form the basement for the deposition of Proterozoic sediments, have
been delineated. Results of the present study detailed in this paper may help to understand better some of
the structural features in this region, which had not been ascertained in earlier studies.
