Overturning

Overturned strata in the Caledonian Mountains on the Cornish coast at Millook

The term overturning , also known as inverse storage , is used in stratigraphy to describe a sequence of rock layers in the sedimentary rock that are inclined over 90 ° to the horizontal. This creates a reverse ( inverse ) storage, in which, for example, by folding older layers are placed on top of younger layers. Overturned layers are common in fold mountains . A tipping over can be recognized by the formation of the strata and by the reverse sequence of fossil deposits that can be assigned to a specific time .
