| Giersdorf_00000849 | The study area is located in the vicinity of the town of Dalbeattie (Kircudbrightshire, south-west Scotland), on the north coast of the Solway Firth. The regional geology has been summarized by Miller and Taylor (1966). The area is mainly underlain by strongly folded Silurian metasedimentary rocks intruded by the Criffell pluton, a late Caledonian (397 _+ 2 Ma, Halliday et al. 1980) granodiorite. This batholith is surrounded by an aureole of contact hornfelses. Carboniferous limestones are present in the coastal area. They are faulted against the Silurian metasediments, through a major NE SW structure dipping 45 ~ to the SE, and known as the coastal fault, since Miller and Taylor have shown that it is responsible for the long, straight, shoreline feature in the Colvend Southwick area (Fig. 1). Much evidence of shearing (ubiquitous southerly dipping shear planes, associated with brecciation, silicificatiom and the development of clay fault gouge) has been observed along this structure by the same authors. In the Needle's Eye area (in the Southwick Coast Wildlife Reserve), the coastal fault runs parallel to the foot of an ancient sea cliff about 35 m high that marks the southern edge of the Criffel batholith. The structure itself, and the Carboniferous limestones to its south are largely covered by Quaternary coastal sediments which are known as the Merse. These postglacial estuarine deposits, about 1-2 m thick, stretch from the base of the cliff to a tidal creek, the Southwick Water. The upper layers of the Merse sediments correlate with the last major (Flandrian) rise in the Irish Sea-level about 6000 7000 years ago (Hooker 1990). |
