2020, Chemical GeologyCitation Excerpt :Surface-derived fluids in the LTGF contain Ba due to interaction with the carbonate-evaporite sequences in the UR (Cavarretta et al., 1982). These observations are also consistent with the temperature – secondary permeability dependence discussed above for the granite samples and published fluid inclusion data (Cathelineau et al., 1994; Boiron et al., 2007). Initial formation of the HT vein white mica was during an intrusive or contact metamorphic episode and after cooling of the system below 400 °C, surficial-derived fluids interacted at various degrees with the vein and host rock white mica and variably lowered their δ18O values.
Formation of magmatic brine lenses via focussed fluid-flow beneath volcanoes
2018, Earth and Planetary Science LettersCitation Excerpt :Direct sampling is relatively limited spatially, due to the challenges of deep drilling into hot rocks and the difficulty of recovering pristine fluids. Deep boreholes drilled through geothermal reservoirs in Japan (Kakkonda; Kasai et al., 1998) and Italy (Lardarello; Cathelineau et al., 1994) have identified brines as an important component of the subsurface fluid inventory. However, in both cases the fluids are recovered at temperatures lower than those at which they would have been released from the parent magmas.
