Further west towards the hinterland, crystalline basement is increasingly involved in this thrusting, imbricate stacking occurring beneath the d\u00e9collement in antiformal windows. The sedimentary successions were derived from the Cryogenian rifted margin of Baltica, the Ediacaran\u2013Cambrian drifted margin, and Ordovician and Silurian foreland basins. During the Early\u2013Late Ordovician (Floian\u2013Sandbian), hinterland-derived turbidites were deposited in response to early Caledonian accretion of subducted complexes belonging to the outermost margin of Baltica, now preserved in the higher allochthons. Following a quiescent period during the Late Ordovician (Hirnantian) and early part of the Llandovery, collision of Laurentia and Baltica reactivated the foreland basins, with flysch and molasse deposition during the Llandovery\u2013Wenlock. Collisional shortening during this Scandian orogenic episode continued into the Devonian. High- and ultrahigh-pressure (HP\/UHP) metamorphism accompanied Baltica's underthrusting of Laurentia in the deep hinterland, and prominent basement-cored antiforms developed towards the foreland during the advance of the orogenic wedge over the foreland basin onto the Baltoscandian platform.<\/jats:p>","DOI":"10.1144\/m50-2018-7","type":"journal-article","created":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T21:09:28Z","timestamp":1578690568000},"page":"495-515","update-policy":"https:\/\/doi.org\/10.1144\/crossmark-policy","source":"Crossref","is-referenced-by-count":22,"title":["Chapter 20\u2003Lower thrust sheets in the Caledonide orogen, Sweden: Cryogenian\u2013Silurian sedimentary successions and underlying, imbricated, crystalline basement"],"prefix":"10.1144","volume":"50","author":[{"given":"David G.","family":"Gee","sequence":"first","affiliation":[{"name":"Department of Earth Sciences, Uppsala University, Villav\u00e4gen 16, SE-752 36 Uppsala, Sweden"}]},{"given":"Michael B.","family":"Stephens","sequence":"additional","affiliation":[{"name":"Department of Civil, Environmental and Natural Resources Engineering","place":["Lule\u00e5, Sweden"]},{"name":"Lule\u00e5 University of Technology","place":["Lule\u00e5, Sweden"]}]}],"member":"1881","published-online":{"date-parts":[[2020,1,10]]},"reference":[{"key":"e_1_3_4_2_1","series-title":"Sveriges geologiska unders\u00f6kning","volume-title":"The Scandinavian Alum Shales","author":"Andersson A.","year":"1985","unstructured":"AnderssonA., DahlmanB., GeeD.G. & Sn\u00e4llS. 1985.
