d18O_c: Equilibrium carbonate d18O value

In isogeochem: Tools for Stable Isotope Geochemistry

Equilibrium carbonate d18O value

Description

d18O_c() calculates the equilibrium d18O value of a carbonate grown at a given temperature.

Usage

d18O_c(temp, d18O_H2O_VSMOW, min, eq)

Arguments

temp	Carbonate growth temperature (°C).
d18O_H2O_VSMOW	Water d18O value expressed on the VSMOW scale (‰).
min	Mineralogy. Options are as in a18_c_H2O().
eq	Equation used for the calculations. Options depend on mineralogy and are listed in a18_c_H2O().

Value

Returns the equilibrium carbonate d18O value expressed on the VSMOW scale (‰).

Note

Use to_VSMOW() and to_VPDB() to convert between the VSMOW and VPDB scales.

References

References are listed in the description of a18_c_H2O().
