You observe a distinct, red sandstone rock body about 50 m thick that is depositionally overlain by a red shale with interbedded gypsum and you follow this boundary in the rock bodies for 1 km until you cross a fault which has displaced the boundary
between the two rock bodies. You walk along the fault and see a boundary between a 50 m thick red sandstone and overlying red shale interbedded with gypsum. You conclude ________.
A) the second exposure of sandstone, shale and gypsum correlates to the first, and the boundary between the sandstone and shale is the same stratigraphic horizon
B) this is impossibly complex; the fault broke up all the rocks
C) this new exposure of sandstone, shale and gypsum must be a different age rock unit
D) the stratigraphic section must have been inverted by the deformation; the rocks are upside down
