Figure F37. Summary of generalized chert color by age for the Cretaceous at ODP Leg 198 and DSDP Leg 32 sites on Shatsky Rise. Red represents oxidized hues of brown, orange, red, and pink, whereas black represents reduced hues of olive-green, gray, and black. Note the similar regional temporal trends in chert color.
