“…In recent years, the understanding of the magmatic plumbing system within sedimentary basins has been revolutionised by the study of seismic reflection data sets. In particular, the opacity rendering technique has provided important insights into intrusion geometry, emplacement mechanisms and the magma flow of sill complexes in basins located on the Norwegian Margin (Planke et al, 2005;Wall et al, 2010;Phillips et al, 2017;Omosanya, 2021), the NE Atlantic Margin (Bell and Butcher, 2002;Davies et al, 2002;Planke et al, 2005;Hansen and Cartwright, 2006;Schofield et al, 2012a), offshore Australia (Symonds et al, 1998;Rey et al, 2008;Jackson, 2012), the western Indian margin (Calvè s et al, 2011;Pandey and Pandey, 2015;Corfield et al, 2022) and the South China Sea (Sun et al, 2013(Sun et al, , 2014Wu et al, 2014;Chen et al, 2015;Lu et al, 2017;Chen et al, 2018;Geng et al, 2020). Field observations and seismic reflection-based studies have shown that: (1) sills typically consist of saucer-shaped sills and strata-concordant sills;…”
