runoff after heavy rainfall often increases the sediment load of nearby water bodies. In addition, mining may modify stream morphology by disrupting a channel, diverting stream flows, and changing the slope or bank stability of a stream channel. These disturbances can significantly change the characteristics of stream sediments, reducing

Therefore, we see a sequence (from bottom to top) of: limestone shale sandstone. A maximum regression occurs where the coarsest sediments reach the farthest seaward. Remember: This process can occur where not all the rock types are present (due to an unconformity) or where coarser sediment is deposited from farther inland. In other words, you ...
