Reverse stratigraphy

    '''Reverse Stratigraphy:''' The result when one sediment is unearthed by human or natural actions and moved elsewhere whereby the latest material will be deposited on the bottom of the new sediment and progressively earlier material will be deposited higher and higher in the stratigraphy Such events can be triggered by rockslides treethrows or other events which cause the strata of a deposit to be flipped or reversed This process is also sometimes refered to as inverted stratigraphyIn Archeological excavation a common cause of inversions in the stratigraphy is the collapse of walls on river banks or other raised mounds where deposits which have been cut through behind the wall prior to collpase slip over the collapsed structure resulting in the structure being under the deposits that originated earlier in time
