Researchers from the University of Exeter in the United Kingdom studied the Toarcian
Oceanic Anoxic Event that occurred in the middle of the Jurassic Period.
For this purpose, the Upper Sinemurian, Pliensbachian and Lower Toarcian
(Lower Jurassic) deposits of the Asturian Basin in northern Spain, including more than 100 m thick succession containing organic-rich and black shale deposits, have been studied.
A sixth core contains Toarcian
marine organisms from the Lower Jurassic, which opens a new window into the geology of the Herald Arch region.
Formation is considered to be of Early Jurassic as its overlying sediments (Shinawri Formation) have revealed characteristic Early Toarcian
