High-precision dating of the Kalkarindji large igneous province, Australia, and synchrony with the Early–Middle Cambrian (Stage 4–5) extinction
The voluminous Kalkarindji flood basalts erupted in Australia during the Cambrian and covered >2 × 106 km2. New U-Pb and 40Ar/39Ar age data from intrusive rocks and lava flows yielded statistically indistinguishable ages at ca. 511 Ma, suggesting a relatively brief emplacement for this province....
