The Mt. Read Volcanics: strontium and neodymium isotope geochemistry

Strontium and neodymium isotope analysis have been carried out in an attempt to answer some of the questions relevant to the genesis of the Mt. Reid Volcanics and their contained ores. The isotope geochemistry of the low-grade metamorphosed basalt-andesite-dacite-rhyolite suite reveals a complex interaction between mantle and crust, with both isotopes highlighting the importance of the crustal component as a potential ore source. 4 refs., 2 figs
