They represent evaporation of the old formation waters, with a characteristic increase in the heavier isotopes. Only sabkha waters in areas of tidal flooding (the narrow creek areas) can be shown to be evaporated seawater. The δ18 O and δD values of the residual brine increase to about +...

An unknown element Q has two known isotopes: ^{60}Q and ^{63}Q. If the average atomic mass is 62.0 amu, what are the relative percentages of the isotopes? Boron has two stable isotopes, ^10 B (mass = 10.012938 amu) and ^11...
A section of caudal penduncle muscle was dried at 55 °C, ground and ≈1 mg was used for carbon and nitrogen stable isotope quantitation at the University of California at Davis Stable Isotope Facility. We also measured isotopes from tissue sampled from mussels (filter-feeding basal pelagic...
Although stable isotopes have been widely used to quantify the relative contribution of external and local organic C sources in coastal ecosystems, there is a cross overlap between the δ13C values of mangrove and terrestrial plants. In subsequent research, it would be useful to separate multiple ...
