Brucite-driven CO<inf>2</inf> uptake in serpentinized dunites (Ligurian Ophiolites, Montecastelli, Tuscany)
2017, LithosCitation Excerpt :The Cu–Fe ores are made up of sulphide nodules, hosted in a soapy and sheared assemblage of chlorite, Ca-rich amphibole and serpentine, that resembles Cu–Fe VMS oceanic deposits (Bertolani and Rivalenti, 1973; Boschi and Dini, 2015). Available petrologic-geochemical data on Tuscan serpentinized peridotites are limited (Boschi et al., 2009; Hébert et al., 1989; Langone et al., 2013; Mellini et al., 2005; Serri et al., 1985; Tribuzio et al., 2004), with only few detailed mineralogical and nano-structural studies (Rumori et al., 2004; Viti et al., 2005). The study area is located near the medieval village of Montecastelli (Southern Tuscany), at the periphery of the Larderello–Travale geothermal area (Fig. 1; Dini et al., 2005).

2012, Gondwana ResearchCitation Excerpt :The gabbro and gabbronorite are cut by plagioclase- and cpx-phyric diabasic intrusives and thondhjemite (Zhang et al., 1982). These compositions are typical of early fractionated crystal from primitive melt (Hébert et al., 1989). The volcanic section is made of purple to green massive and pillowed basalts.
