In recent years, many kimberlite pipes were discovered in Eastern Dharwar Craton by public and private organizations. Majority of diamondiferous pipe clusters occur in Anantapur District of Andhra Pradesh state. Lattavaram kimberlite cluster is one among them and the four pipes in this cluster are reported to be diamondiferous. A spatial and statistical study based on geochemistry of clay fraction (-80 mesh) of the stream sediments, in south of Lattavaram Kimberlite Cluster, for major and minor element was carried out. Subsequent data interpretations revealed that sediments in the proximity of the pipe have dominance of certain trace elements as observed in the primary kimberlite. The dispersion patterns through geochemical mapping showed that certain elements like TiO<sub>2</sub>, CaO, Na<sub>2</sub>O, Nb, Co, Ni, and Zr have higher pulses. Correlation exists between major oxides and minor elements from which anomalous areas can be detected. It is envisaged that stream sediment geochemistry can be used as a regional exploration tool in identifying the provenance, prioritizing the catchments and thereby locating kimberlite pipes.
