The mantle section of the ophiolite is made of diopside-bearing harzburgite, harzburgite and dunite characteristic of a lherzolite-harzburgite ophiolite type (LHOT). The plutonic section is essentially composed of troctolites, wehrlites and gabbros locally intruded by ilmenite-rich mafic dykes. All the rocks were strongly affected by an ocean-floor hydrothermal metamorphism. The composition and evolution of primary magmatic phases (olivine, clinopyroxene, plagioclase and spinel) throughout the lowermost magmatic sequence correspond to those described in oceanic cumulates (ODP data). The Limousin ophiolite is thus of MOR type instead of SSZ type. The whole lithological section, the mineral chemistry, the extensive hydrothermal oceanic alteration and the relatively thin crustal section are typical of a slow-spreading ridge ocean (i.e. Mid-Atlantic ridge). Comparison of the Limousin ophiolite with other ophiolites from European Variscides suggests that the oceanic domain was actively spreading during the Late Palaeozoic and extended from the Armorican massif to the Polish Sudetes.<\/jats:p>","DOI":"10.1180\/0026461067020322","type":"journal-article","created":{"date-parts":[[2006,6,3]],"date-time":"2006-06-03T17:34:56Z","timestamp":1149356096000},"page":"175-185","source":"Crossref","is-referenced-by-count":19,"title":["A Variscan slow-spreading ridge (MOR-LHOT) in Limousin (French Massif Central): magmatic evolution and tectonic setting inferred from mineral chemistry"],"prefix":"10.1180","volume":"70","author":[{"given":"J.","family":"Berger","sequence":"first","affiliation":[]},{"given":"O.","family":"F\u00e9m\u00e9nias","sequence":"additional","affiliation":[]},{"given":"J.C.C.","family":"Mercier","sequence":"additional","affiliation":[]},{"given":"D.","family":"Demaiffe","sequence":"additional","affiliation":[]}],"member":"7149","published-online":{"date-parts":[[2018,7,5]]},"reference":[{"key":"S0026461X00027882_ref13","doi-asserted-by":"publisher","DOI":"10.1038\/337729a0"},{"key":"S0026461X00027882_ref30","first-page":"137","volume-title":"Ophiolite Concept and the Evolution of Geological Thought","volume":"373","author":"Nicolas","year":"2003"},{"key":"S0026461X00027882_ref2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00320902"},{"key":"S0026461X00027882_ref28","doi-asserted-by":"publisher","DOI":"10.1016\/0009-2541(95)00033-I"},{"key":"S0026461X00027882_ref36","doi-asserted-by":"publisher","DOI":"10.1016\/0040-1951(90)90282-D"},{"key":"S0026461X00027882_ref41","doi-asserted-by":"publisher","DOI":"10.1016\/S0024-4937(03)00095-1"},{"key":"S0026461X00027882_ref27","doi-asserted-by":"publisher","DOI":"10.1016\/0012-821X(88)90048-9"},{"key":"S0026461X00027882_ref40","doi-asserted-by":"publisher","DOI":"10.1016\/0024-4937(88)90009-6"},{"key":"S0026461X00027882_ref16","doi-asserted-by":"crossref","first-page":"49","DOI":"10.1007\/s710-002-8215-9","article-title":"Relicts of eclogite-facies metamorphism in the Austroalpine basement Hochgr\u00f6ssen (Speik complex), Austria","volume":"74","author":"Faryad","year":"2002","journal-title":"Mineralogy and Petrology"},{"key":"S0026461X00027882_ref7","doi-asserted-by":"publisher","DOI":"10.1130\/0091-7613(1995)023<0049:TCUEAR>2.3.CO;2"},{"key":"S0026461X00027882_ref49","doi-asserted-by":"publisher","DOI":"10.1007\/s005310100200"},{"key":"S0026461X00027882_ref1","doi-asserted-by":"publisher","DOI":"10.1130\/0091-7613(1986)14<848:CMOACG>2.0.CO;2"},{"key":"S0026461X00027882_ref3","doi-asserted-by":"crossref","first-page":"795","DOI":"10.1111\/j.1525-1314.2005.00610.x","article-title":"Ocean-floor hydrothermal metamorphism in the Limousin ophiolite (Western French Massif Central): Evidence of a rare preserved Variscan oceanic marker","volume":"23","author":"Berger","year":"2005","journal-title":"Journal of Metamorphic Geology"},{"key":"S0026461X00027882_ref19","doi-asserted-by":"publisher","DOI":"10.1016\/0009-2541(89)90074-0"},{"key":"S0026461X00027882_ref38","first-page":"63","article-title":"Sr-Nd isotope and trace element evidence for a late Devonian active margin in northern Massif Central (France)","volume":"15","author":"Pin","year":"2002","journal-title":"Geodynamica Acta"},{"key":"S0026461X00027882_ref48","doi-asserted-by":"publisher","DOI":"10.1016\/0009-2541(93)90078-W"},{"key":"S0026461X00027882_ref32","doi-asserted-by":"publisher","DOI":"10.1016\/S0040-1951(00)00210-9"},{"key":"S0026461X00027882_ref9","doi-asserted-by":"publisher","DOI":"10.1139\/e77-105"},{"key":"S0026461X00027882_ref34","doi-asserted-by":"publisher","DOI":"10.1016\/S0024-4937(02)00166-4"},{"key":"S0026461X00027882_ref24","first-page":"65","volume-title":"Ophiolites: Ocean Crustal Analogues","author":"Malpas","year":"1990"},{"key":"S0026461X00027882_ref11","unstructured":"Dubuisson, G.
