Abstract
Lamprophyre dykes are reported from the Precambrian metamorphites of the Chotanagpur Gneissic Complex near Simdega, Gumla district, Jharkhand. Petrological and petrochemical studies indicate that they are calc-Alkaline lamprophyres. The economic significance of these lamprophyres is discussed in light of their proximity to (i) the gold prospects in its strike continuity and (ii) reported occurrences of diamonds in the major drainage basins of the region.Downloads
