Abstract Throughout the Latest Triassic and Early Jurassic, major changes in paleogeography, climate eustatic sea-level impacted on development of shelf depositional environments. Secular trends environmental conditions were punctuated by transient perturbations that occurred relation to large-scale volcanic events, such as emplacement Central Atlantic Magmatic Province at Triassic/Jurassic boundary Karoo–Ferrar Large Igneous early Toarcian. We here present bulk organic (HAWK programmed...

The Carnian Stuttgart-Formation (Schilfsandstein) of the Central European Basin contains relics Triassic volcanic detritus in form euhedral zircon grains and authigenic analcime. Multiple LA-ICP-MS spot analyses single crystals from an outcrop near Heilbronn (SW Germany) yielded weighted average 206 Pb/ 238 U ages between 250 230 Ma, providing evidence for tephra fallout southern part related to Olenekian, Anisian–Ladinian activity. was probably transported by monsoonal circulations centres...
