Measured stratigraphic section of the Lockatong Formation at Byram, NJ. controls the first-order depositional Depth rank is a relative measure of water depth. Fourier analysis of the depth-rank curve reveals that Van Houten cycles average 5.9 m thick, and that the 100 kyr and 400 kyr eccentricity cycles are 28 m and 96 m thick, respectively. The blue curve envelops the Van Houten cycles to define the 100 kyr cycle. The red curve envelops the blue curve to define the 400 kyr cycle. The named members of the Lockatong Formation correspond to the 400 kyr cycles. Modified from Olsen et al. (1989).
