How do organic rocks form
For decades, it was thought that the majority of the organic-rich sedimentary beds deposited on the ocean floor was a byproduct of three environmental variables: the input of organic material, the rate of sedimentation, and the amount of deep-water oxygenation. These variables are linked on spatial and temporal scales by climate, ocean currents, and sea-level at the time of deposition. Any changes in the variables or the parameters that link them will result in different sedimentary … WebSedimentary rocks cover about three‐fourths of the surface of the continents.
