Repository: Late fluid flow in a primitive asteroid revealed by Lu–Hf isotopes in Ryugu

This repository contains data generated in Iizuka et al. "Late fluid flow in a primitive asteroid revealed by Lu–Hf isotopes in Ryugu". Included herein are 4 spreadsheets that contain information on the chemical and isotopic compositions of 4 Ryugu samples (A0106, A0106-A0107, C0107, and C0108), along with those of 6 carbonaceous chondrites (CI Orgueil and Alais, CM Murchison, CV Allende, and ungrouped chondrites Tagish Lake and Tarda).
