This thickening cannot be explained readily by Caledonian thrust tectonics alone, and suggests that thrusting was superimposed upon a pre-Caledonian non-layer-cake template giving rise to a thrust-parallel thickness change of Torridon Group strata in the thrust belt. Cross-section constructions within the culmination constrain discrete abrupt thickness changes of the Torridon Group succession preserved within the Coire nan Clach and Toll Ban thrust sheets. We infer the existence of a pre-existing discontinuity in the form of either a set of pre-Caledonian faults striking parallel or sub-parallel to the long-lived Loch Maree Fault in its southwestern wall, or palaeovalleys creating locally greater thicknesses of Torridon Group sediments in the pre-thrust template. Such palaeovalleys may have been eroded along pre-existing discontinuities. In either case, these discontinuities will have contributed to generating step-wise thickness changes in preserved Torridon Group strata prior to Cambro-Ordovician overstep and then contributed to controls on the observed (lateral) variations in thrust architecture and the northwards step-wise thinning of the Achnashellach Culmination towards the Loch Maree Fault. This northern termination of the Achnashellach Culmination demonstrates the importance of the pre-thrust template in constraining the three-dimensional architecture of lateral changes within fold-and-thrust belts.\n          <\/jats:p>","DOI":"10.1144\/sjg2015-002","type":"journal-article","created":{"date-parts":[[2016,10,19]],"date-time":"2016-10-19T02:39:28Z","timestamp":1476844768000},"page":"103-109","source":"Crossref","is-referenced-by-count":1,"title":["Evidence for pre-Caledonian discontinuities in the Achnashellach Culmination, Moine Thrust Zone: the importance of a pre-thrust template in influencing fold-and-thrust belt development"],"prefix":"10.1144","volume":"52","author":[{"given":"Tomas","family":"Cain","sequence":"first","affiliation":[{"name":"Basin Dynamics Research Group, Geography, Geology and the Environment, Keele University, William Smith Building, Keele, Staffordshire ST5 5BG, UK"}]},{"given":"Graham","family":"Leslie","sequence":"additional","affiliation":[{"name":"British Geological Survey, The Lyell Centre, Research Avenue South, Edinburgh, EH14 4AP"}]},{"given":"Stuart","family":"Clarke","sequence":"additional","affiliation":[{"name":"Basin Dynamics Research Group, Geography, Geology and the Environment, Keele University, William Smith Building, Keele, Staffordshire ST5 5BG, UK"}]},{"given":"Michael","family":"Kelly","sequence":"additional","affiliation":[{"name":"Basin Dynamics Research Group, Geography, Geology and the Environment, Keele University, William Smith Building, Keele, Staffordshire ST5 5BG, UK"}]},{"given":"Maarten","family":"Krabbendam","sequence":"additional","affiliation":[{"name":"British Geological Survey, The Lyell Centre, Research Avenue South, Edinburgh, EH14 4AP"}]}],"member":"1881","published-online":{"date-parts":[[2016,10,18]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0191-8141(96)80012-5"},{"key":"e_1_3_2_3_1","doi-asserted-by":"crossref","unstructured":"Beacom L.E.
