sample_remark Early intrusion within the Omeo Zone with arc-type geochemistry. Magmatic crystallisation is expected to be 430-400 Ma (Middle Silurian to Early Devonian) based on ages of nearby intrusions. FROM ASUD: Biotite tonalite: coarse grained, grey I-type with rare round mafic igneous enclaves, fine grained grey muscovite-bearing S-type (refid 23029); non- and intensely magnetic phases; no distinctive radiometric response (refid 23030). Mafic and magnetic phase sampled.
