(A) Outline geological map of the River North Esk section NW of Edzell, and the location of samples NE11A, 129–134. The position of the Highland Boundary Fault is obscured by the outcrop of the Lintrathen Porphyry (not shown). (B) Simplified geological map of the HBC in North Glen Sannox, Isle of Arran, showing the location of samples GS60–69. In this area, both the Southern Highland Group and the HBC dip and young to the east. The contact of the HBC with the overlying Old Red Sandstone (ORS) is either an unconformity or a fault. The geology of both areas is based on unpublished mapping by PWGT.

Optical micrographs showing bedding, cleavage, deformed objects and veins in some of the analysed chert samples. (A) North Glen Sannox (GS61). The bedding trace in the chert lies E-W in the illustration and is cut by an early opaque-rich vein (1) and by at least three generations of quartz veins (2–4). (B) A folded quartz microvein in chert from North Glen Sannox (GS64) showing features typical of buckle folding, such as (1) a slightly offset finite neutral point; (2) an axial planar cleavage related to the inner arc of the fold; and (3) recrystallized quartz fabric in the vein. (C) North Glen Sannox (GS64). A boudinaged and folded early vein in chert, marked twice (1) cut by later sets of quartz veins (2 & 3). Py, euhedral pyrite. (D) Details of the microfabric in the grey chert in (G) below, showing the orientation of laths of white mica. (E) The matrix in (B) showing the preferred orientation of the laths of white mica. (F) River North Esk (NE122). Jasper containing haematite-rich patches (black) slightly elongated parallel to (?)cleavage, and cut by several generations of now recrystallized quartz veins. (G) Loch Ard Forest (A224). Black chert band (1), mentioned in the text, which has a sharp contact with pale grey chert (2) on one side and a diffuse one on the other and contains a deformed reduction spot (3). (H) Stonehaven (SA97). Early quartz veins (1), cut by several generations of calcite veins (2), and containing a sheared and recrystallized fragment of silt (3). (I) An enlargement of part of (H) showing the cleavage defined by mica laths (Cl), that is markedly oblique to the haematite-rich streaks and patches (black). (J) An enlarged image of the deformed object in (H), which is augened in the cleavage, giving a top-to-right shear sense.
