Abstract
Tale valley is a NE-SW oriented oval shaped basin situated between alt itudes 2278 and 2870 m above MSL in Lower Subansiri District of Arunac hal Pradesh. Upper Quaternary sediments measuring about 11.85 m unconf ormably rest over the crystallines in the valley sides of Karing nala, the main tributory in the valley. Radiocarbon dating (C-14) Of peaty clay in the lower part of the sequence provides 25400 +/- 750 yrs. B.P . for the sediments, equivalent to Upper Pleistocene age. Lithology su ggests glacio-lacustrine and glacio-fluvial environment of deposition.
