[48] can be applied to ASCs as a solution; in particular, quanti- tative isotope measurements of 15N2 gas were used to increase the reliability and reduce the cost. In compu- tational experiments, standardization is also important to ensure that the simulated activity and selectivity can ...
These isotope evidences indicate contribution of juvenile sources in petrogenesis of the Tarom-Olya pluton. Geochemical and isotopic data suggest that the parental magma of the Tarom-Olya pluton was mainly derived from a sub-continental lithospheric mantle source, which was metasomatized by fluids ...
