Abstract
We present here the plausible causes for heteropigmentation of leaf im pressions formed within the Karai-laminated clays. Geomorphic, mineral ogical and sedimentological studies reveal that the different colourat ion of the leaf impressions are due to anaerobic, reducing, oxidizing, micro-environmental conditions formed in a shallow to deep, near-shor e lake environment.
