Cycle Development and Diagenesis of a Large Late Triassic Carbonate Platform, Hungary

匈牙利晚三叠世旋回台地碳酸盐岩的岩心和露头剖面将被研究，以确定为什么一些旋回记录了海侵（lofer型）演替，而另一些旋回记录了退退演替。Fischer图将用于定义相对的长期（三阶）海平面曲线，并将其与已发表的晚三叠世曲线进行比较。循环剖面将使用光谱分析来确定是否有任何主要的周期发生，如果是，可能的原因是什么。计算机建模将模拟相序列、旋回叠加模式、可能的沉降速率、3至5级海平面波动的可能幅度和周期、可能的沉积速率范围以及海平面低潮期间旋回的可能出现时间。将研究该序列的成岩作用，以确定高低频海平面波动与保存岩石的成岩记录的关系（如果有的话），以及众多旋回盖层不整合与晚中生代和新生代不整合的关系。这项工作将确定浅层碳酸盐岩台地的沉积成岩记录对其海平面和构造历史的忠实程度。

Cores and outcrop sections of Late Triassic, cycle platform carbonates in Hungary will be studied to determine why some cycles record a transgressive (Lofer-type) succession, whereas other cycles record a regressive succession of facies. Fischer plots will be used to define relative, long-term (3rd order) sea level curves, which will be compared to published Late Triassic curves. Cyclic sections will be examined using spectral analysis to define if any dominant periodicities occur, and if so, what were likely causes. Computer modeling will simulate facies successions, cycle stacking patterns, possible subsidence rates, likely amplitude and periods of 3rd to 5th order sea level fluctuations, possible ranges of sedimentation rates, and likely emergence times of cycles during sea level lowstands. The diagenesis of the succession will be studied to determine the relationship, if any, of high and low frequency sea level fluctuations to the diagenetic record preserved the rocks, and the relationship of the numerous cycle-capping disconformities, and Late Mesozoic and Cenozoic unconformities. The work will define how faithfully a shallow carbonate platform's sedimentary diagenetic record records its sea level and tectonic history.
