Syn-metamorphic recrystallization and release of trace elements may be responsible for formation of diverse accessory minerals parageneses (Cook, 1996;Cook et al, 1998;Hofmann and Knill, 1996;Marshall et al, 1998;Eremin et al, 2007;Taylor et al, 2010). fO 2 and fS 2 conditions may play a key role as well in the remobilization of element like Ge, as this will control which Ge-mineral crystallizes.…”

“…In published studies silver‐rich members of the tetrahaedrite group have been regarded as primary crystallization products (Wu & Petersen, 1977; Hackbarth & Petersen, 1984; Arlt & Diamond, 1998; Sack, 2002; Sack et al ., 2003), solid state reaction products (Cook, 1996; Cook et al ., 1998; Sack & Goodell, 2002; Sack et al ., 2002, 2005), or products resulting from element incompatibilities (Johnson et al ., 1988; Ebel & Sack, 1989, 1991). Sack and coworkers have interpreted, in tetrahedrite, the compositional variations by Zn↔Fe substitution in the assemblages of tetrahedrite + sphalerite and Cu↔Ag substitution in the assemblage of tetrahedrite + bournonite + galena, in terms of the solid state reaction during the cooling process.…”

Chemical compositions of tetrahedrite-Ag-rich tetrahedrite-freibergite solid solutions (Ag-rich tetrahedritess) and homogenization temperatures of fluid inclusions in quartz and carbonates of seventeen samples from nine veins in the El Zancudo deposit, Antioquia, Colombia, were investigated to reveal the origin of silver in Ag-rich tetrahedrite ss, to derive their crystallization temperatures and to examine the relationship between chemical compositions of Ag-rich tetrahedritess and their crystallization temperatures. The ores consist of arsenopyrite, pyrite, sphalerite, Ag-rich tetrahedritess, galena, boulangerite, andorite, owyheeite, diaphorite, jamesonite, miargyrite, bournonite, chalcopyrite, and electrum. Ag-rich tetrahedritess forms about 10 volume % of the total ores and is one of the most common and widely distributed sulfosalts in this deposit. Ag-rich tetrahedrite ss is rich in Ag (1.13 to 31.02 wt%) and Sb (22.93 to 29.82 wt%), and poor in As (0.06 to 2.43 wt%), consistent with the reported incompatibilities of Ag and As in Ag-rich tetrahedritess. The Zn/(Zn + Fe)-, Ag/(Ag + Cu)-and Sb/(Sb + As + Bi)-atomic ratios exhibit some variations among the veins. Ag-rich tetrahedritess with higher Ag/(Ag + Cu) ratios coexist with diaphorite, whereas those with lower ratios are not associated with this sulfosalt. Ag-rich tetrahedrite ss in the assemblages of Ag-rich tetrahedritess + sphalerite and of Ag-rich tetrahedritess + bournonite + galena shows no Zn ↔ Fe and Cu ↔ Ag variations between core and rim, respectively, negating the possibility of solid state reaction during cooling. Ag-rich tetrahedritess is thus regarded as primary phase. Homogenization temperatures of primary fluid inclusions in quartz and carbonates co-existing with Ag-rich tetrahedrite ss define the mineralization temperatures of 134 to 263°C. Independent crystallization temperatures of Ag-rich tetrahedrite estimated based on Zn/(Zn + Fe) and Ag/(Ag + Cu) ratios of the Ag-rich tetrahedrite ss associated with silver minerals such as miargyrite, andorite and diaphorite using Sack's thermochemical database lie in a range between 170 and~250°C. Both results are thus in good agreement.
