Petrographic and lithochemical characteristics of the upper middle – upper Jurassic of the lower reaches of the Anabar river are presented. Patterns of change in rock-forming oxides contents in silty-sandy rocks of the upper part Yuryungtumusskaya Fr., Sodyemikhainskaya Fr. and silty-clay rocks Buolkalahskaya Fr. are revealed. Petrographic and lithochemical features of specific "junk" and phosphorite layers are noted.
