Supplemental Material: 40Ar/39Ar age evidence for an impact-generated hydrothermal system in the Devonian Siljan crater, Sweden

Abstract

Supplemental Material 1: Item S1 (additional information on ⁴⁰Ar/³⁹Ar age spectra of biotite), and Item S2 (additional information on ⁴⁰Ar/³⁹Ar age spectra of amphibole); and Supplemental Material 2: Tables S1–S4 (Ar isotopic ratios, apparent ages, J values, Ar isotopic abundances, and Ca/K and Cl/K ratios).
