Deep groundwater characteristics provide valuable information on oil and gas extraction
and evolution of hydrosphere, and nonmetallic and metallic elements in deep groundwater …

This study aims at identifying the sources and fate of salinity in the Djebeniana basin
(Tunisia) aquifers. Groundwater samples from the shallow Plio-Quaternary (PQ) phreatic …

The foundations of stable isotope geochemistry were laid in 1947 by Urey's classic paper on
the thermodynamic properties of isotopic substances and by Nier's development of the …

Here we report on a set of six apatite reference materials (chlorapatites MGMH# 133648,
TUBAF# 38 and fluorapatites MGMH# 128441A, TUBAF# 37, 40, 50) which we have …

Significant bromine (Br) isotope composition variations are found in natural salts and brines,
which are often even larger than those of co-existing chlorine isotope compositions. The …

Chloride is the most important anion in ore-forming hydrothermal fluids, and chlorine
isotopes are therefore potentially sensitive tracers of the origin and evolution of ore-forming …

Marine evaporitic halite, precipitating from the advanced stage of extremely evaporated
seawater, is the most common and abundant evaporitic mineral. The extent to which lithium …

We investigate the chlorine isotope disequilibrium between chlorides in pore fluids and
chlorides in seawater and infer its consequences for chlorine isotope exchange between …

Because of the large-scale recycling of volatile chlorine from the interior to the surface of the
Earth, it is possible to use the isotopic composition of this element (δ 37 Cl) in serpentinite to …

Abstract Published values, near 1.0003, of the fractionation factor for stable Cl isotopes
between halite and brine (α hal-br) fail to account for several sets of δ 37 Cl data for marine …
