Abstract

Lofer cycles are lagoonal-peritidal cycles that are characteristic of extremely thick and broad carbonate platforms along the margin of the Upper Triassic Tethys. In the Transdanubian Mid-Mountains borehole sections expose continuous sequences of the cyclic platform carbonates several hundred metres thick. Sedimentological investigations and statistical analyses have revealed that the cycles consists of symmetric and asymmetric sequences 2-5 m thick. The ideal cycle is fairly symmetric but many cycles are condensed or incomplete and truncated. The cycles are related to relatively small-scale sea-level variations, which has resulted in considerable lateral facies migrations in a wide, marginal carbonate platform. Periodicities are estimated to range between 20 and 40 ka, and are suggestive of orbital control. -Author
