Rutile in diamondiferous metamorphic rocks: New insights from trace-element composition, mineral/fluid inclusions, and U-Pb ID-TIMS dating

From microanalysis to supercontinents: Insights from the Rio Apa Terrane into the Mesoproterozoic SW Amazonian Craton evolution during Rodinia assembly

“…The high F content of white‐mica between 0.65% and 0.04% from sample FMR162 supports the presence of F‐rich fluids and a metasomatic origin of rutile. HFSE‐enriched rutile has been an important pathfinder for ore deposits across different tectonic settings (Porter et al, 2020; Rezvukhina et al, 2021; Scott et al, 2011; Scott & French, 2005; Tollo & Haggerty, 1987), and the presence of this HFSE‐enriched niobian rutile in two samples of the Caracol Complex is promising for tracking potential deposits of critical metals (e.g., Nb and Ta).…”

Deep Subduction in Earth history: Seeking for traces in the sedimentary record

“…In contrast to zircon, rutile growth is more common in HP metamorphic rocks and less frequent in mantle rocks, igneous rocks, and hydrothermal systems (e.g., Force 1980;Zack & Kooijman 2017). Consequently, rutile of high-pressure metamorphic origin is inherently enriched in the sediment factory and rutile growth at UHP conditions is confirmed by reports of coesite (Hart et al 2016) and diamond inclusions (Massonne 2003;Rezvukhina et al 2021). Furthermore, the chemical composition of rutile enables to discriminate (i) mantle rutile by higher aluminum and magnesium contents (Smythe et al 2008) as well as higher zirconium to hafnium ratios (Pereira et al 2019) compared to crustal rutile, and (ii) igneous and hydrothermal rutile from metamorphic rutile by concentrations and ratios of niobium, tantalum, zirconium, hafnium, tungsten, antimony, zinc, vanadium, chromium, and iron (Clark & Williams-Jones 2004;Agangi et al 2019;Pereira et al 2019).…”

“…Besides garnet, coesite and diamond inclusions have been frequently detected in other host minerals like zircon (e.g., Parkinson & Katayama 1999;Massonne 2003), clinopyroxene (e.g., Smith 1984Shatsky & Sobolev 1993), and chromite (e.g., Robinson et al 2004;Yamamoto et al 2009). In addition, they were also found in tourmaline (e.g., Ota et al 2008;Marschall et al 2009), rutile (e.g., Hart et al 2016;Rezvukhina et al 2021), kyanite (e.g., Massonne 2003;Taguchi et al 2019), titanite (Ogasawara et al 2002), zoisite (Shatsky & Sobolev 1993), epidote (Zhang et al 1995), and dolomite .…”
