This is based upon the following factors: (1) the presence of Early Palaeozoic basement and stratigraphic correlation of sequences between the autochthonous and previously proposed allochthonous terranes; (2) isotopic evidence for similar deep crustal structure across the different terranes; (3) ocean island basalt magmas and deep marine sedimentary rocks formed during continental margin extension within the previously proposed accretionary wedge sequence (i.e. not formed against an active oceanic arc); (4) the distribution of magnetic susceptibility measurements and aeromagnetic data locating the palaeo-subduction zone along the west of the Peninsula; (5) a lack of clear palaeomagnetic distinction between the terranes. The following alternative tectonic history is proposed: (1) amalgamation and persistence of Gondwana; (2) subsequent silicic large igneous province magmatism and extension; (3) development and history of Andean subduction until its cessation in the Cenozoic. A number of features in the Antarctic Peninsula correlate with those of other circum-Pacific margins, supporting a global evaluation of allochthonous v. autochthonous margin development to aid our understanding of crustal growth mechanisms.\n          <\/jats:p>","DOI":"10.1144\/jgs2014-110","type":"journal-article","created":{"date-parts":[[2015,8,5]],"date-time":"2015-08-05T01:10:30Z","timestamp":1438737030000},"page":"822-835","source":"Crossref","is-referenced-by-count":100,"title":["Autochthonous v. accreted terrane development of continental margins: a revised\n            <i>in situ<\/i>\n            tectonic history of the Antarctic Peninsula"],"prefix":"10.1144","volume":"172","author":[{"given":"A.","family":"Burton-Johnson","sequence":"first","affiliation":[{"name":"British Antarctic Survey, High Cross, Madingley Road, Cambridge CB3 0ET, UK"}]},{"given":"T.
