摘要：

The Gravity survey area is located south of the Godavari basin in Eastern Dharwar Craton. Bouguer gravity anomaly is prepared which is based on 965 observations acquired at 200-meter station interval in and around the Armoor region (18 degrees 30'N-19 degrees 00'N and 78 degrees 00'E-78 degrees 30'E) in Nizamabad district, Telangana state of India, covering an area of about 604 sq km. The Bouguer gravity anomaly reveals the variance from-33 mGal to-54 mGal. The qualitative analysis of the Bouguer gravity anomaly map, low-pass, high-pass filtered and tilt derivative maps, reveal a combination of E -W, N-S and NW-SE trends that coincide with the lineaments and deep-seated faults present in the region. Six highs (H1-H6), three lows (L1-L3), and four deep-seated faults (F1-F4) are identified in this area. The high anomalies are attributed to the basement rocks, basic dykes and mineralized zones (banded magnetite quartzite) while low anomalies correspond to the variations in the peninsular gneissic complex.
