“…For example, in peralkaline systems, zirconium shows a high solubility and a highly incompatible nature in the melt until the final stages of crystallization (Bowden 1966, Larsen 1973, Watson 1979, Dunn & McCallum 1982, Linthout 1984, Rubin et al 1993. The high solubility of Zr in alkali-rich magmas can be attributed to the fact that Zr acts as a network modifier (Linthout 1984).…”

“…It is located north of the town of Van Horn and is reached from State Highway 54. The regional and local geology around Marble Canyon have been described by Bridge (1966aBridge ( , 1966bBridge ( , 1980Bridge ( , 1986, Gregg and Sibley (1984), Price and Henry (1986), Henry andPrice (1986), andPrice et al (1986), and their discussions are summarized here. The canyon is elongate, approximately 1.5 km long and 1 km wide.…”

“…Although there are studies that have examined the influence of inorganic ligands on the solubility of silicate and phosphate phases (Saxena 1966, Kraynov 1969, Giere 1989, Rubin et al 1993, Fayek and Kyser 1997, Cherniak 2000, Poitrasson et al 2000, Cherniak and Watson 2001, Trocellier and Delmas 2001, Geisler et al 2002, Nagy et al 2002, few studies have considered the influence of organic ligands. Organic ligands have been shown to occur in subsurface fluids (e.g., Carothers and Kharaka 1978, Giordano and Kharaka 1994, Fein 1994) and, they can enhance porosity in sedimentary basins by dissolution of silicate minerals such as feldpars (Fein 1994).…”

“…O ácido fluorídrico (HF) é o único ácido capaz de dissolver, embora com dificuldade, o zircão (Rubin et al 1993). A presença de fluorita, bastnaesita e oxifluoreto de ETR nos granitos greisenizados e greisens desenvolvidos sobre a fácies g1b mostra que o F era um elemento comum no fluido hidrotermal.…”

“…Como esse fluido também era aquoso (Botelho 1992), pode ter havido a formação de HF que levaria à destruição parcial do zircão durante o hidrotermalismo. Elementos comumente considerados muito pouco móveis, como Zr e ETR, podem ser transportados para fora do sistema na forma de fluoretos (Kosterin 1953, Alderton et al 1980Baker 1985;Pointer et al 1988;Rubin et al 1993;Aja et al 1996 entre outros). Por ser pobre nos ETR (tabela 2), a diminuição na quantidade de zircão durante a greisenização não afetou o conteúdo dos ETR em rocha.…”
