| Abstract: | Twenty one basaltic flows of known mineralogical and chemical composition from the Deccan of western India have been analyzed for nine rare-earth elements (REE), together with Hf, Ta and Th by instrumental neutron activation methods. The flows, which are tholeiites and transitional alkali basalts, are relatively enriched in the Light REE and have total REE abundances systematically related to their bulk petrochemistry. The results are compared with REE abundances of basalts from other provinces. |
