Analytical/Numerical Modeling of Komatiite Lava Emplacement and Thermal Erosion at Perseverance, Western Australia
We have applied a thermal-fluid dynamic-geochemical model to investigate the emplacement and erosional potential of Archean komatiite flows at Perseverance, Western Australia. Perseverance has been proposed as a site of large-scale thermal erosion by large-volume komatiite eruption(s), resulting in a 100-150-m-deep lava channel containing one of the world's largest komatiite-hosted Fe-Ni-Cu-(PGE) sulfide deposits. Using constraints based on field, theoretical, and geochemical data, we have...[Show more]
