Reaction microtextures in entrapped xenoliths in alkali basalts from the Deccan large igneous province, India: Implications to the origin and evolution

•Lithospheric fragments entrapped in alkali basalts document reaction microtextures.•Aggregate of systematically arranged tiny diopside crystals defines Flower texture.•Orthopyroxenes in contact with infiltrated melt exhibit reaction corona.•Clinopyroxenes and spinels close to orthopyroxene corona display sieve texture.•Melt-Lithosphere interaction explains all the microtextural variants.
