Table S1: The Highland Border Complex, NE Scotland, revisited: its role in Laurentian rifting, Early Ordovician emplacement and later faulting at the Highland Boundary

Table S1. Sedimentary data. Selected major and trace element analyses (by XRD) from the Dalradian (Robertson and Henderson 1984), including tuffaceous sediments (Batchelor 2004), and from the HBC. The HBC sediments are from the Margie unit and from interlava sediments, from both the North Esk and Stonehaven (Robertson and Henderson 1984). Samples: Highland Border Complex: RH84, Robertson and Henderson (1984); BA04, Batchelor (2004). Locations: NE, North Esk; SM, South Margie; Abfyl, Aberfoyle; SI-lava, Stonehaven interlava; LL clasts, Loch Lomond clastics; DalS, Dalradian sandstone; DalT, Dalradian tuff. Lithologies: bl shale, black shale; pk shale, pink shale; silst, siltstone; bl sst, black sandstone; SFe seds, Stonehaven iron-rich interlava sediments; Sblsh, Stonehaven interlava black shale; Sredct, Stonehaven interlava red chert; volcsst, volcaniclastic sandstone; sst, sandstone; volc mdst, volcaniclastic mudstone; blslate, black slate; puslate, purple slate.
