Paleohydrogeological events recorded by stable isotopes, fluid inclusions and trace elements in fracture minerals in crystalline rock, Simpevarp area, SE Sweden

Trace metal distribution and isotope variations in low-temperature calcite and groundwater in granitoid fractures down to 1km depth

“…Bath and Ruotsalainen, 2000;Tullborg et al, 2008). Additionally, the small volumes often carrying only minor amounts of U (commonly <0.02 ppm, Drake and Tullborg, 2009) have generally disabled successful U-series dating (cf. Gascoyne et al, 2004), in contrast to other settings (e.g.…”

“…In Proterozoic and Archaean crystalline settings, fracture-calcite studies have mostly focused on hydrothermal precipitates (e.g. Blyth et al, 2000;Gehö r et al, 2002;Drake and Tullborg, 2009;Sandströ m and Tullborg, 2009), which are abundant and often >100 Ma (cf. Drake et al, 2009b;Sandströ m and Tullborg, 2009).…”

Paleo water–rock interaction determined through isotopic tracing (Sr, O, C, U) in fracture-fill minerals: Evidence from the Vienne granitoids (France)

“…It is well agreed that the 87 Sr/ 86 Sr ratio shows conservative behaviour between the originating fluids and derived solids (Boulègue et al, 1981;Casanova et al, 1999;Barrat et al, 2000;Drake and Tullborg, 2009). Hence the composition of the fluids from which the AEM precipitated can be estimated from 87 Sr/ 86 Sr ratios in the solid phases.…”

“…In addition, generations of matrix and fracture-fill minerals may also contain some sort of geochemical record (e.g. O, C, Sr isotopes) of the compositions of the groundwaters from which they precipitated (Clauer et al, 1989;Stuckless et al, 1991;Marshall et al, 1992;Gao et al, 1992;Tullborg et al, 2008;Drake and Tullborg, 2009). Isotope tracers are useful tools for deciphering the origin of fluids and diagenetic conditions (Suchy et al, 2000;Morad et al, 2010); fluids and hydrothermal systems (Hecht et al, 1999;Barker et al, 2009;Staude et al, 2011) and deep fluid processes in fault systems (Kopf et al, 2003;Boiron et al, 2003).…”
