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

چکیده
Upper Triassic sedimentary systems of both the Arabian Plate and Germanic Basin reveal climate- 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, isotope anomalies. Further, Moon recession changes Earth’s rotation velocity (core/mantle boundary) are associated with multiple impacting large igneous provinces/Mid Oceanic Ridge Basalt, LIP/MORB-rifting/degassing. While acidification (by degassing, sturz-rain) does influence tectosilicates carbonates, montmorillonite represents a key mineral as transformation volcanic/impact glass (Tephra) to be found co-components in pelite units “boundary clay-suspicions” (mixture eolian paleoloess, pelite, paleosol, tephra → tuffite). Obviously, unconformities sequence boundaries study areas separate dislocate interrupted ∂13C 87Sr/86Sr-data groups along curves. Both Proto-Arctic Ocean rifting/degassing comprising kimberlitic pyroclastic eruptions Neotethys well played most important role during Norian, followed incipient Central Atlantic Magmatic Provinces rifting since Rhaetian. The following associations encountered dealt this study: Sequence boundaries-∂13C, surfaces-(FUCs)-∂13C, unconformities-plate motion, tephra-pelite-tuffite-montmorillonite. Norian: surfaces (MFSs)-“paleosol”/boundary clay?-rifting-volcanism, Moon/Earth data change. So Norian (~221 - 206 Ma) hosts anomalous “amalgamated (MFSs)”, amalgamated paleosol (Jordanian Platform), (~219 214 Ma), opening (PAO) (~230 200 Neo-Tethys (NT)-subvolcanic (sills, dikes) NE Dead Sea area prior Rhaetian, significant change Earth/Moon relation data. concludes that rare extreme events very strongly shaping geologic constellations Earth System.

Climate changes caused by degassing of sediments during the emplacement of large igneous provinces
11 Most mass extinctions during the last 500 m.y. coincide with eruptions of large igneous 12 provinces (LIP): the Cretaceous-Tertiary extinction was synchronous with the Deccan 13 flood volcanism, Permian-Triassic extinction with the eruption of the enormous 14 Siberian Traps, and End-Guadalupian extinction with the Emeishan volcanic province. 15 The causal link remains disputed, however, and ...

Physical volcanology of continental large igneous provinces: update and review
Large igneous provinces (LIPs) form in both oceanic and continental settings by the emplacement and eruption of voluminous magmas ranging from basalt to rhyolite in composition. Continental flood basalt provinces are the best studied LIPs and consist of crustal intrusive systems, extensive flood lavas and ignimbrites, and mafic volcaniclastic deposits in varying proportions. Intrusive rocks are...
متن کاملLarge Igneous Provinces: Crustal Structure, Dimensions, and External Consequences
Large igneous provinces (LIPs) are a continuum of voluminous iron and magnesium rich rock emplacements which include continental flood basalts and associated intrusive rocks, volcanic passive margins, oceanic plateaus, submarine ridges, seamount groups, and ocean basin flood basalts. Such provinces do not originate at "normal" seafloor spreading centers. We compile all known in situ LIPs younge...
متن کاملImpact induced melting and the development of large igneous provinces
We use hydrodynamic modelling combined with known data on mantle melting behaviour to examine the potential for decompression melting of lithosphere beneath a large terrestrial impact crater. This mechanism may generate sufficient quantity of melt to auto-obliterate the crater. Melting would initiate almost instantaneously, but the effects of such massive mantle melting may trigger long-lived m...
