Collection of heavy or path finder minerals, which are highly resistant to weathering, from stream sediment/loam/ clacrete samples is one of the main technique employed in Kimberlite exploration which has led to the discovery of many Kimberlite pipes world wide. An multi disciplinary approach using known geology, aeromagnetic and remote sensing data can effectively narrow down the area of search in avirgin area. By this a favourable zone/area map was prepared. Collection of stream sediment and calcrete samples from these favourable zones and careful processing of the same to extract indicator/pathfinderminerals , supported by Electron Probe Micro Analyser (EPMA) studies have facilitated the location oftwo propspective Kimberlite zones in the area South West of Mahabubnagar town, Telangana. The Kimberlite bodies are totally soil covered with no ground signatures. With the adjoining areas to the north the Maddur Kimberlite field and on the west Narayanpet Kimberlite field, the principle of Known to Unknown was used. Garnets, Ilmenites, Phologopites are the path finder minerals recovered and their mineral chemistry indicates Kimberlite affinity, which has led to narrow down two areas for further ground geophysical survey for delineating the exact location of the Kimberlite.
