Abstract
Anomalously high contents of Nb (818 ppm), La (173 ppm), Y (305 ppm) a nd Zr (> 1000 ppm) are reported for the first time in the rhyolite dyk es/veins spatially associated with the Deccan basalts in Alech hills a round Dhorio Nes, district Jamnagar, Gujarat. The enrichment of these elements is due to influx of alkalies and volatiles in rhyolites empla ced along the western continuity of E-W-trending Son-Narmada rift.
