Effects on Sedimentary Processes via Upper Triassic Climate Forcing Caused by Multiple Impacting and Large Igneous Provinces (LIP)-Rifting/Degassing: Jordanian Platform/Arabian Plate and Germanic Basin/Central Europe

Abstract

Upper Triassic sedimentary systems of both the Arabian Plate and the Germanic Basin reveal climate-and plate tectonic-forced effects through certain time-intervals experienced by architectural elements, lithofacies types, unconformities, flash flood deposits, maximum flooding surfaces/sequence boundary (MFS/SB), mineralogy, and isotope anomalies. Further, Moon recession and changes of Earth's rotation velocity (core/mantle boundary) are associated with multiple impacting and large igneous provinces/Mid Oceanic Ridge Basalt, LIP/MORB-rifting/degassing. While acidification (by degassing, sturz-rain) does influence tectosilicates and carbonates, montmorillonite represents a key mineral as transformation of volcanic/impact glass (Tephra) to be found as co-components in and in certain pelite units as "boundary clay-suspicions" (mixture of eolian paleoloess, pelite, paleosol, and tephra  tuffite). Obviously, unconformities and sequence boundaries of both study areas separate and dislocate interrupted ∂ 13 C and 87 Sr/ 86 Sr-data groups along the isotope curves. Both Proto-Arctic Ocean rifting/degassing comprising kimberlitic pyroclastic eruptions and Neotethys rifting/degassing as well as multiple impacting played the most important role during the Norian, followed by the incipient Central Atlantic Magmatic Provinces rifting since the Rhaetian. The following associations are encountered and dealt with in this study: Sequence boundaries-∂ 13 C, maximum flooding surfaces-(FUCs)-∂ 13 C, unconformities-plate motion, tephra-pelite-tuffite-montmorillonite.

Formation Mechanisms of Some Features in Siliceous Upper Cretaceous-Lower Tertiary Beds of Jordan-Undulations, Geodes, Boudinages

“…Decrease in the pH-values results from the production of CO 2 , NO x , and eventual SO 2 because of bacterial reduction of dissolved O 2 , nitrates and sulfates from the siliceous beds. Volcanic activity can also contribute in increasing acidity of the water by releasing gases such as HCl, HS, and CO 2[15]. Cretaceous Large Igneous Provinces have caused a decrease in the pH-values of the water and the deposited sediments that enabledE.…”
