On the origin of vesuvianite-rich rodingites from the Western Carpathians, Slovakia

A petrochronological study of Fe Ti oxides in rodingites of the Western Carpathians, Slovakia

“…" 2013). The yellow star marks the investigated serpentinite and rodingite occurrence (see also Butek et al 2022). The red star marks the Dobšiná rodingite occurrence (Butek et al, 2021) where dating of perovskite formation allowed to constrain the age of serpentinization processes (Li et al 2014).…”

“…Rodingites are hosted by intensively serpentinized ultramafic bodies tectonically incorporated into Gemeric metasediments of Carboniferous age. For more details on the regional geology and the outcrop, the reader is referred to Butek et al (2022).…”

“…The investigated samples represent a product of intense rodingitization of a gabbroic protolith (Butek et al, 2022). They consist predominantly of vesuvianite, diopside, hydrated garnet and titanite.…”

“…Fe-Ti oxides (rutile, ilmenite, titanomagnetite, ulvospinel or magnetite) are common accessory minerals in many metamorphic, magmatic and also detrital rocks. Rodingites are no exception and often contain minor amounts of these phases, mainly rutile and ilmenite (Butek et al, 2022;Koutsovitis et al, 2018Koutsovitis et al, , 2013Laborda-López et al, 2018;Nishiyama et al, 2017). Any attempt to date the metasomatic process with rutile U-Pb geochronology requires a good understanding of 1) the relationship between fluid circulation and Fe-Ti oxide phase equilibria and 2) behaviour of the chemical and isotopic systems during and after mineral crystallization.…”

“…This study focuses on rodingitized gabbroic rocks associated with an ophiolite fragment in the Western Carpathians, the Bôrček serpentinite body, which has been presented in detail by Butek et al (2022). Through a combination of textural analysis and U-Pb LA-ICPMS dating, we discuss the reaction scheme of Ti-rich minerals during rodingitization, and demonstrate that hydrothermal rutile can provide a chronological record of the Cretaceous metasomatism and can help to discuss the timing of rodingite formation in the framework of the regional geodynamical evolution.…”
