I need some help figuring out how the sequence of sediment layers are formed in the ocean in relation to the movement of plate tectonics and plate boundaries. For example if I was to look at a core from a drill site and decide what the sediment type would be on top and the one below it etc. The sediment types that I am working with are terrigenous, biogenous, and hydrogenous.View Full Posting Details
