Radio-bio-cyclo-magneto-stratigraphy solves longstanding problems of the global Triassic: astronomically paced aquifer-eustasy, interregional platform correlation, and geologic time

During the severe hothouse of the Early Triassic, astronomically forced global sea level oscillations interpreted from marine stratigraphy from South China are anti-phased with continental water storage variations interpreted from fluvial-lacustrine sequences in the Germanic Basin. This intepretation is according to correlation of magnetic reversals in the sequences at both localities, and solves the longstanding problem of major sea level oscillations during ice-free geologic periods. Middle Triassic astronomically forced strata of the Guandao carbonate platform, South China correlate to the Latemar platform and Buchenstein basin in the Italian Dolomites, by correlation of magnetic reversals MT6 and MT7. This strengthens the millennial-scale interpretation of the Latemar cycles, the timing of which has been the subject of controversy for the past 30 years. These solutions to longstanding problems of the global Triassic have been made possible through integration of high-precision radioisotope dating, biostratigraphy, magnetostratigraphy, and cyclostratigraphy.
