Potential source rocks are any type of sedimentary rock that the ability to dispel available carbon from within it ( limestone is a classic example of a source rock).
WebAll are inorganic sedimentary rocks Limestones ( inorganic)form when chemical changes/high water temp increase water's concentration of calcium carbonate to the point that it precipitates. When travertine (limestone) commonly seen in caves,is deposited in caves, groundwater is the source of the calcium carbonate. 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 …
