Description Usage Arguments Value Note References See Also Examples

View source: R/d18O.R

Description

temp_d18O() calculates carbonate growth temperature from oxygen isotope data.

Usage

1
temp_d18O(d18O_c_VSMOW, d18O_H2O_VSMOW, min, eq)

Arguments

d18O_c_VSMOW

Carbonate d18O value expressed on the VSMOW scale (‰).

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 listed in a18_c_H2O().

Value

Returns the carbonate growth temperature (°C).

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().

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

d18O_H2O() calculates the d18O value of the ambient water from the d18O value of a carbonate and its growth temperature.
