Understanding which subduction-zone architectures and structural boundary conditions favour the subduction of MTDs, primarily deposited in oceanic trenches, is therefore highly significant. We use bathymetric and seismic reflection data from modern convergent margins to show that a large landslide volume and long runout, in concert with thin trench sediments, increase the chances for an MTD to become subducted. In regions where the plate boundary develops within the upper plate or at its base (non-accretionary margins), and in little-sedimented trenches (sediment thickness &lt;2 km), an MTD has the highest potential to become subducted, particularly when characterized by a long runout. On the contrary, in the case of a heavily sedimented trench (sediment thickness &gt;4 km) and short runout, an MTD will only be subducted if the thickness of subducting sediments is higher than the thickness of sediments under the MTD. The results allow identification of convergent margins where MTDs are preferentially subducted and thus potentially alter plate-boundary seismicity.<\/jats:p>","DOI":"10.1144\/sp500-2019-174","type":"journal-article","created":{"date-parts":[[2019,12,19]],"date-time":"2019-12-19T09:15:14Z","timestamp":1576746914000},"page":"115-128","update-policy":"https:\/\/doi.org\/10.1144\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Structural constraints on the subduction of mass-transport deposits in convergent margins"],"prefix":"10.1144","volume":"500","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5625-493X","authenticated-orcid":false,"given":"Jacob","family":"Geersen","sequence":"first","affiliation":[{"name":"GEOMAR Helmholtz Centre for Ocean Research Kiel, Wischhofstrasse 1\u20133, 24148 Kiel, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5325-0263","authenticated-orcid":false,"given":"Andrea","family":"Festa","sequence":"additional","affiliation":[{"name":"Dipartimento di Scienze della Terra, Universit\u00e0 degli Studi di Torino, Via Valperga Caluso 35, 10125 Torino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0720-1927","authenticated-orcid":false,"given":"Francesca","family":"Remitti","sequence":"additional","affiliation":[{"name":"Dipartimento di Scienze Chimiche e Geologiche, Universit\u00e0 di Modena e Reggio Emilia, via Campi 103, 41125 Modena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1881","published-online":{"date-parts":[[2020,3,13]]},"reference":[{"key":"e_1_3_4_2_1","volume-title":"AGU Fall Meeting Abstracts","author":"Barnes P.","year":"2018","unstructured":"BarnesP., GamboaD., BellR.E., MooreG.F., MountjoyJ.J., PaganoniM. and RabinowitzH. 2018.
