Chhaktalao area situated 25 km NE of Ambadongar, is characterised by six flows of Deccan Trap. Of these two are tholeiitic basalts, one picrite basalt and three basaltic andesites. These flows are intruded by east-west trending dolerite, olivine dolerite, lamprophyres and carbonate-rich dyke-like bodies. In this paper the genetic relation between the flows and the dykes (dolerite and olivine dolerite) are discussed. Trace element geochemistry suggests that crustal contamination is not significant and did not play any vital role in the evolution of the lava flows and dykes. The dolerite and olivine dolerite dykes and mafic members of the flows show similar trace element characteristics indicating a broad chemical affinity between these two magmatic phases.Keywords
