tatric_HfR Documentation

Hafnium isotopic dataset for the detrital zircons from the Tatric Unit (Slovakia)

Description

A dataset of in-situ (LA ICP-MS) Lu–Hf isotopic analyses and U–Pb ages for detrital zircons from the Tatric Unit (Western Carpathians, Slovakia) (Soejono et al. 2024).

Usage

sampleDataset("tatric_Hf")

Format

A data frame containing 179 detrital zircon analyses (Lu–Hf isotopic ratios and U–Pb ages) from 5 samples of metasedimentary rocks of the Tatric Unit.

Details

This is a subset of detrital zircon dataset from a comprehensive compilation of Soejono et al. (2024). Included here are only data from two metasandstones (UT3, UT6), two paragneisses (UT1, UT14) and a single micaschist (UT5) from the Lower and Upper complexes of the Tatric Unit (for sample locations, see Fig 1c below adopted from the original work).
