Recent research has shown that material from this plume modified the melts in the Palaeotethys subduction zone. However, it remains poorly understood whether, in turn, the subduction of Palaeotethys affected the formation of the Emeishan LIP. We report here geochronological, petrological, geochemical and isotopic studies of a gabbroic intrusion located in Jiangwei, in the Dali area of the Emeishan LIP. The gabbro has a weighted mean SHRIMP U\u2013Pb age of\n            <jats:italic>c.<\/jats:italic>\n            262\u2005Ma. The key geochemical features include: depletion in Nb, Ta and Ti; enrichment in Th, U and Sr; low light to heavy rare earth element ratios;\n            <jats:sup>87<\/jats:sup>\n            Sr\/\n            <jats:sup>86<\/jats:sup>\n            Sr\n            <jats:sub>(t)<\/jats:sub>\n            values of\n            <jats:italic>c.<\/jats:italic>\n            0.707; and\n            <jats:inline-formula>\n              <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" overflow=\"scroll\">\n                <mml:mi>\u03b5<\/mml:mi>\n              <\/mml:math>\n            <\/jats:inline-formula>\n            Nd\n            <jats:sub>(t)<\/jats:sub>\n            values of\n            <jats:italic>c.<\/jats:italic>\n            \u22120.21. We conducted pMELTS thermodynamic modelling and batch-melting calculations to evaluate the origin and evolution of the gabbro based on real components of low-Ti picrites and xenoliths from the Yangtze lithosphere. Our results show that 3% melting of a hydrated spinel peridotite source from the Yangtze lithosphere can produce magma equivalent to the gabbroic intrusion. Integrating this conclusion with the tectonic background of the western Yangtze plate and the volcano-stratigraphic record of the Emeishan LIP, we infer that the early-stage magmatism of the Emeishan LIP was triggered by Palaeotethys back-arc extension with fluid modification from the subducting slab.\n          <\/jats:p>\n          <jats:p content-type=\"supplementary-material\">\n            <jats:bold>Supplementary material:<\/jats:bold>\n            Tables S1\u2013S7 are available at\n            <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" specific-use=\"dataset is-supplemented-by\" xlink:href=\"https:\/\/doi.org\/10.6084\/m9.figshare.c.5433267\">https:\/\/doi.org\/10.6084\/m9.figshare.c.5433267<\/jats:ext-link>\n          <\/jats:p>","DOI":"10.1144\/jgs2020-224","type":"journal-article","created":{"date-parts":[[2021,5,25]],"date-time":"2021-05-25T11:50:13Z","timestamp":1621943413000},"update-policy":"https:\/\/doi.org\/10.1144\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Low-Ti gabbroic pluton in Dali, SW China: new evidence for back-arc lithospheric melting inducing early-stage magmatism of the Emeishan large igneous province"],"prefix":"10.1144","volume":"178","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3104-0529","authenticated-orcid":false,"given":"Bei","family":"Zhu","sequence":"first","affiliation":[{"name":"School of Geoscience and Technology, Southwest Petroleum University, Chengdu, Sichuan 610500, China"},{"name":"Key Laboratory of Orogenic Belts and Crustal Evolution, Ministry of Education, School of Earth and Space Sciences, Peking University, Beijing 100871, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaojie","family":"Guo","sequence":"additional","affiliation":[{"name":"Key Laboratory of Orogenic Belts and Crustal Evolution, Ministry of Education, School of Earth and Space Sciences, Peking University, Beijing 100871, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaonan","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Geoscience and Technology, Southwest Petroleum University, Chengdu, Sichuan 610500, China"},{"name":"State Key Laboratory of Oil and Gas Reservoir Geology and Exploration, Southwest Petroleum University, Chengdu, Sichuan 610500, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ning","family":"Ye","sequence":"additional","affiliation":[{"name":"School of Geoscience and Technology, Southwest Petroleum University, Chengdu, Sichuan 610500, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziye","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Geoscience and Technology, Southwest Petroleum University, Chengdu, Sichuan 610500, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Baiwen","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Geoscience and Technology, Southwest Petroleum University, Chengdu, Sichuan 610500, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1881","published-online":{"date-parts":[[2021,6,25]]},"reference":[{"key":"e_1_3_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0009-2541(03)00165-7"},{"key":"e_1_3_5_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-444-42148-7.50008-3"},{"key":"e_1_3_5_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-246X.2009.04238.x"},{"key":"e_1_3_5_5_1","doi-asserted-by":"publisher","DOI":"10.18814\/epiiugs\/2013\/v36i3\/002"},{"key":"e_1_3_5_6_1","doi-asserted-by":"publisher","DOI":"10.1029\/JB089iS02p0B525"},{"key":"e_1_3_5_7_1","doi-asserted-by":"publisher","DOI":"10.1029\/2001GC000217"},{"key":"e_1_3_5_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.lithos.2010.04.008"},{"key":"e_1_3_5_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.oregeorev.2011.07.005"},{"key":"e_1_3_5_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.lithos.2017.01.013"},{"key":"e_1_3_5_11_1","first-page":"2646","article-title":"The composition and age of subcontinental lithospheric mantle beneath Maguan, Yunnan province: cnstraints from Re\u2013Os isotopes of mantle-derived peridotitic xenoliths","volume":"27","author":"Huang X.","year":"2011","unstructured":"Huang, X., Mo, X., Yu, X., Li, Y. and Li, X. 2011.
