... and Hawick groups are divided by geochemical lineaments coincident with the Laurieston Fault. East of Moffat, the geochemical lineaments diverge towards the NE with Gala-type regional geochemistry (high Sr and Ba, low CaO) to the north of the Moffat Valley Fault, whilst Hawick-type regional geochemistry (low...

Examples are given from the Silurian turbidite sequences of the central and southern Southern Uplands (Gala, Hawick and Riccarton groups; the affinity of the Ross Formation with the Hawick Group...

... structures appear to record a single regional phase of subhorizontal NW–SE contractional deformation, with a steeply dipping direction of bulk finite extension. These structures are markedly different from those developed in rocks correlated with the Upper Llandovery Hawick Group exposed some 5 km...

... particularly instructive. Much of the Down-Armagh outcrop consists of Llandovery strata from the Gala and Hawick Groups, so it is this part of the terrane that is most closely considered. Though continuity is clear, there is a suggestion of additional structural imbrication in Down-Armagh, whilst variability...

...-propagating thrust stack which deformed the back-arc basin sequence and may eventually have ramped over the eroded and faulted remains of the volcanic arc. A southward-migrating foreland basin formed ahead of the rising thrust stack and is now represented by the late Llandovery Hawick Group and Wenlock...

... as in the Northern Belt. Southward this becomes markedly less pronounced, particularly in Down where the Central Belt is much wider than in Galloway. Distinctive Hawick Group lithologies permit the correlation of the southern parts of the sections. Large areas of predominantly southward-younging occur in each...

... and intensity of folding and cleavage show a marked increase in the late Llandovery to early Wenlock strata of the Hawick Group (including the Ross Formation, which was formerly assigned to the Riccarton Group). Therein, the main deformation (Dl) is well developed and although cleavage is domainal it is often...

A more detailed correlation has been established ( Barnes et al . 1987 ) for the Gala and Hawick tracts on either side of the North Channel, in the Rhins of Galloway (Scotland) and the Ards Peninsula (Northern Ireland). From this it is apparent...

Vanadium and MgO show the reverse trend (Fig. 3 b,c ). Overall, where Cr increases, V and MgO remain more-or-less...

The Llandovery to early Wenlock sandstones in the western part of the Southern Uplands are divided lithologically into the Gala and Hawick groups, the former essentially Aeronian in age, and the latter Telychian, although the Gala Group extends into the early Telychian and overlaps in age with the older part...
