modelZhong {imputeREE}

Model REE contents using the method of Zhong et al. (2019)

Description

This function apply the logarithmic regression using the method of Zhong et al. (2019). This method considers the relationship between the logarithm of the REE atomic number vs their chondrite normalized values. For more information refer to the Zhong et al. (2019) and Carrasco-Godoy and Campbell (2023) for a discussion of its limitations to calculate La or Ce*.

Usage

modelZhong(
  dat,
  exclude = c("La", "Pr", "Ce", "Eu", "Y"),
  Calibrate = F,
  chondrite = PalmeOneill2014CI,
  prefix = NULL,
  suffix = NULL
)

Arguments

dat

A data frame with REE data in ppm

exclude

a string: vector including elements that should be omitted from modelling. La, Ce and Eu are the default. Ce and Eu should be always included

Calibrate

Logical (T or F). If True, the model is calibrated using the correction factors. By default it is the reciprocal of the median REE from the work of Carrasco-Godoy and Campbell is used.

chondrite

an option from: PalmeOneill2014CI, Oneill2014Mantle, McDonough1995CI

prefix

A prefix in your columns e.g. ICP_La

suffix

A suffix in your columns e.g. La_ppm

Value

a dataframe
