Skagerrak-Centered Large Igneous Province


The Skagerrak-Centered Large Igneous Province, also known as the European-Northwest African Large Igneous Province, and Jutland LIP, is a large igneous province centered on what is today the Skagerrak strait in north-western Europe. It was named by.
The SCLIP covered an area of at least and includes the Oslo and Skagerrak grabens, areas in south-western Sweden, Scotland, northern England, and the central North Sea. The SCLIP erupted at 297±4 Ma.
It produced 228,000 km² of currently exposed volcanic material that can be found in Skagerrak, the Oslo Fjord, central North Sea, North-east Germany; 14,000 km² of sills in Scotland, England, Germany, The Netherlands, and Sweden; and 3,353 km total length of dykes in Scotland, Norway, and Sweden.
The eruption had a relatively short time span, perhaps less than 4 Ma, but magma propagated more than from the plume centre.
Plumes derived from a superplume overlay the boundary of the superplume at the core-mantle boundary. To test whether the SCLIP met these criteria, Torsvik et al. used a shear-wave tomographic model of the mantle, in which the SCLIP indeed do project down to the margin of the African superplume at the CMB at a depth of 2800 km.
A series of LIPs are associated with the African superplume, of which the SCLIP is the oldest: SCLIP, Bachu, Emeishan, Siberian, and Central Atlantic. Its possible that these plumes together caused the break-up of Pangaea and therefore play an important role in the supercontinent cycle.
The SCLIP is associated with the Moscovian and Kasimovian stages of the Carboniferous rainforest collapse around 296-310 Ma together with the Siberian Barguzin-Vitim LIP.
