ABSTRACT The Wajrakarur Kimberlite Field (WKF) in Anantapur, Andhra Pradesh, India, stands as a pivotal region for kimberlite exploration in the South Indian Kimberlite Province. It features distinct gravity highs and lows, sandwiched between Closepet Granite (CG) and Cuddapah Basin (CB), with notable gold‐mineralized Ramagiri‐Penakacherla Greenstone Belt (RPGB) and Jonnagiri Greenstone Belt (JGB). The structural features of gravity modelling include upwarping beneath the western CG and downwarping beneath Peninsular Gneissic Complex‐II (PGC‐II). Gravity signatures allow for the identification of shallow geological features such as granite structures and fault/shear zones around 3–4 km deep in the WKF region, with kimberlite pipes showing a preferential concentration along these zones. Deep‐seated fault structures reveal the area's geological characteristics, offer insights into lithospheric fluid migration, and are key for evaluating fluid flow pathways associated with deep‐seated minerals and kimberlite exploration. The study reveals regional variations and geological characteristics, providing valuable avenues for future research.
