Hardie and his students and colleagues studied cyclic sedimentation, confirming that platform carbonates of the Middle Triassic ( Anisian-Ladinian ) of the Latemar buildup consist of a vertical stack of over 500 thin ( ave . thickness 0.6-0.85m ) shallowing-upward depositional cycles that record high frequency eustatic sea level oscillations in tune to Milankovitch astronomical rhythms.
