Platform crises of the Cenomanian Levant Platform - High-resolution studies of dysoxic sediments (Central Jordan): environmental changes, cycles, palaeoecology

The project focuses on two mayor targets:
A) A high-resolution investigation of the critical crises intervals concerning
the switch from ventilated to dysoxic/anoxic conditions and back into
oxic conditions. Major goals are firstly the palaeoecological reconstruction
of the influence of oxygen-limited conditions on the platform sedimentation.
Secondly, a correlation of the Jordan platform crisis events with the
known boreal events will shed more light on their global triggering mechanisms.
B) High accumulation rates allow for an extraordinarily high time resolution
which enables us to study high-frequency cycles. This is particularly
promising in the mid-Cenomanian Karak Limestone which spans a rather short
(less than 1 Myr) interval and, thus, will likely resolve sub-Milankovitch
cyclicity.
