Abstract: The content of total, nitrate, fixed, exchangeable, and organic nitrogen in Cretaceous and Tertiary formations in two representative drainage basins of the east central Diablo Range was determined. The results of these analyses showed that high concentrations of organic nitrogen (up to 1,200 ?g/g) occur predominantly in the Cretaceous formations while high concentrations of nitrate (up to 4,800 ?g/g) occur predominantly in the younger Tertiary sediments. The concentrations of fixed and exchangeable ammonium were variable and generally low.
