Abstract Rare earth elements (La to Lu, Y and Sc) importance increased with the advent of domestic and industrial uses. The REEs occur in rock forming minerals, younger granites, pegmatites, and in riverine and beach placers. A series of granite plutons are sandwiched between the eastern margin of Cuddapah Basin and Eastern Ghat Belt (EGB) and traced from Vinukonda in the north to Pamuru in the south. These granites are intrusive into the Nellore Schist Belt (NSB) and age range from 995 Ma to 1600 Ma. The granite of Darsi is one such pluton and occur 50 km north east of established rare metal and rare earth bearing Kanigiri granite. The granite samples (n=12) were analysed for REE and Y. The analysis indicates very high values of La (65 -220 ppm), Ce (134-374 ppm), Pr (13 – 38 ppm), Nd (43- 142ppm), Sm (7 – 26 ppm), Y (39-129ppm), LREE (271 -813 ppm), and HREE (13 - 46 ppm). The granite samples show enrichment of LREE over HREE.
Keywords Darsi, Kanigiri, Nellore Schist Belt, granite and REE.
