“…The trend is 10°-20 ° counterclockwise of the trend of topographic lineaments, which are seen by Landsat (Lindh 1980) and which parallel the Klaralven line, part of the regionally defined Protogine zone (Gorbatschev 1980). The left lateral offset in the zones of crustal ages (Stromberg 1976), which is also inferred from an offset in the aeromagnetic anomaly pattern (Riddihough 1972), is entirely consistent with the angularity of the present continental margin along the Jan Mayen fracture zone and apparently reflects the latter's inheritance of cratonic discontinuities. Riddihough (1972) similarly notes the coincidence in trend and continuity in the boundary between the Karalian and Svecofennian fold belts and the Senja fracture zone offnorthern Norway (Talwani & Eldholm 1977), implying similar tectonic inheritance.…”

“…Such a line would be a landward extrapolation of the trend of the Jan Mayen fracture zone NW of the Voring plateau and, according to the reconstruction by Talwani & Eldholm (1977), would have a landfall in Greenland between Kong Oscars Fjord and Gael Hankes Bay. Offsets are indeed recognizable as a change in the trend of the Greenland Caledonides and by contrasts within the Scandinavian Caledonides (Stromberg 1976) as discussed later.…”

Summary Gravity and magnetic data from the Appalachian-Caledonide area demonstrate the overall continuity of the orogen while identifying its segmentation into areas of contrasting structural style. The extension of this segmentation into ‘drift’-covered areas (e.g. the southern U.S.A.) and offshore areas (e.g. around Newfoundland and the British Isles) provides an orogen-wide framework into which structural detail established at outcrop can be accommodated. Linear gravity and magnetic anomalies often reflect contrasts within the Precambrian basement that have controlled tectonic events to the present. Such basement structure has been investigated by deep seismic profiling, which has also identified large-scale thrusting throughout the Appalachians and the Caledonides with some thrusts even extending into the upper mantle. Speculation to greater depths based on conductivity and P-wave travel-time residuals suggests that traces of the early Palaeozoic collision zone may still exist in the lower crust and upper mantle beneath the northern Appalachians. The loading imposed by thrust sheets during that collision produced foreland basins in the eastern USA whose form and sedimentary record indicate the magnitude and duration of thrusting. Palaeomagnetic results suggest transcurrent movement in Devonian-Carboniferous time, but the early Palaeozoic collisional choreography has not yet been uniquely defined.
