Abstract:

Geologically the Investigator Isles comprise three distinctive types of basement granite. Two of these are part of the Hiltaba Suite event, a state-wide series of voluminous predominantly granitic plutons that emplaced ∼1590 Ma ago, whilst the third is an older comagmatic dominantly granite suite outcropping at Seal Point, east Flinders Island. Zircon U–Pb dating of the granite from Pearson Island gave an age of 1590 ± 5 Ma, which demonstrates it is part of the Hiltaba Suite event. The Hiltaba Suite granite on Pearson and Waldegrave islands contain magmatic enclaves of intermediate to mafic composition in addition to fractured microgranite xenoliths, these features are in contrast to the homogeneous Calca Granite of Flinders Island.
