Two-stage release of gold from pyritic sediments during greenschist-facies metamorphism

Description

Data in the manuscript by Jian-Wei Li et al. to be published by Geochimica et Cosmochimica Acta as "Two-stage release of gold from pyritic sediments during greenschist-facies metamorphism".

Steps to reproduce

Trace element compositions of sulfides were determined using a Resonetics S–155–LR 193 nm ArF excimer laser ablation system coupled to an Agilent 7700x quadrupole inductively coupled plasma mass spectrometer (LA–ICP–MS). In situ sulfur isotope analyses were conducted via secondary ion mass spectrometry (SIMS) on a Cameca IMS–1280 instrument. Transmission electron microscopy (TEM) investigations were performed using an FEI Talos F200X G2 TEM at 200 kV and a FEI double Cs-corrected Titan Themis G2 TEM at 300 kV. Details of analytical methods are provided in the Supplemental Material.
