RISDebates—The future of hydrological sciences: A (common) path forward? A call to action aimed at understanding velocities, celerities and residence time distributions of the headwater hydrograph
Investigating geochemistry and the stable isotope (δ 18O & δ 2H) composition of Karde Carbonate lake water (NE Iran)
's salt (Na2SO4) in the upper hand basin.
In the classical plot of δ 18O vs δ 2H, the isotopic signature of lake water samples (-6.82‰, -48.3‰) plot further to (LMWL) comparing to the local ground water (-8.21‰, -57.5‰) and upstream river (-8...

Stable isotope aspects of modern molluscs, brachiopods, and marine cements from cool-water carbonates, Lacepede Shelf, South Australia
Abstract--The isotopic composition of some modern gastropods, bivalves, and brachiopods from the
Lacepede Shelf of South Australia were investigated to determine the isotopic equilibrium and disequilibrium
states of biogenic and non...

Petrography and Geochemical Signatures in Cracks Filling Calcite Sequences in Septarian Concretions, Sanganeh Formation, Kopet-Dagh Basin, NE Iran
isotopes signatures reveal that the septarian concretions are multiphase and display several stages of cementation (G2 to G4). The earliest carbonate matrix (septarian body, called G1) with δ13 C and δ18 O values of 0.01‰ and -21‰ PDB, respectively...
