Rare earth element (REE) analysis for fresh glass and crystalline basalts from the FAMOUS area along the Rift Valley at about 36°N in Atlantic Ocean lying close to the triple junction of North American, Eurasian and African plates, are presented. These rocks display light rare earth element (LREE) patterns with (La/Sm)e.f. ratios ranging between 0.56-0.84 similar to spreading mid-oceanic ridge rocks, suggesting the definite presence of large ion lithophile element (LILE) depleted mantle source in this area. White and Bryan (1977) report the presence of LREE enriched basalts from the FAMOUS area which perhaps resulted due to the effect of the Azores mantle plume. Thus, geochemically the FAMOUS area represents a transitional zone-a mixture of mantle plume and LILE depleted normal ridge.- Petrogenetic Significance of Rare Earth Element Patterns of Selected Samples of Ingaldhal Metavolcanics, Karnataka State, India: Consortium Studies No.1
