Triassic-Jurassic rift basins in the eastern US record an excellent record of high frequency climate change dominated by roughly 25, 44, 100 and 400 k.y. Milankovitch climate cycles reflecting continuous sedimentation in these lacustrine basins (Olsen, 1986). Similarly, Goldhammer et al. (1990) showed a well developed record from a Mid-Triassic carbonate platform from the italian alps dominated by precessional (20 k.y.) and subordinate 100 k.y. eccentricity cycles, however, relatively complete cyclic records with bundling of 5 precessional cycles per eccentricity cycle occurred only during long term low-stand or high-stand when accommodation allowed all beats to be recorded. Similarly, Late Triassic off-shelf facies in the Alps show a strong Milankovitch climate forcing in the Triassic, the authors examined the large Late Triassic carbonate platform in Hungary to attempt to determine how well this large shallow marine platform recorded high frequency sea level changes driven by Milankovitch orbital forcing. A combination of 2 km of detailed logs of cores and outcrops provided a data base.
