The Loch Scridain Sill-complex on the Isle of Mull affords an opportunity to examine how magma moves through and builds sill-complexes (Holness & Humphreys 2003). For example, field and petrological evidence indicates the Tràigh Bhàn na Sgùrra Sill is segmented and comprised several thick channels, separated by thin sill portions, that facilitated longer-lived magma flow (Holness & Humphreys 2003; Stephens et al. 2017). We integrate structural field analysis and rock magnetic techniques in an attempt to identify and characterise magma flow pathways in the LSSC, with a view to expanding the study to understand how the entire sill-complex was constructed.
