Timing of diagenetic events by petrographic relationships. 

Timing of diagenetic events by petrographic relationships.
Description: A) Involvement of isopachous cement in compaction indicates that cement was early.
B) Cement that encases comacted grains and spalled isopachous cement is relatively late.
C) Cross cuttin relationships of features such as fractures and mineral replacements are useful. Calcite filling fracture is latest even, replacement anhydrite came after the late poikilopic cement, but before the fracture, while the isopachous cement was the earliest diagenetic event.
