Kondoolka batholith reinvestigated: an integrated approach

Abstract

The Kondoolka Batholith is an early Mesoproterozoic Hiltaba Suite granite that intruded into the late Paleaoproterozoic to early Mesoproterozoic Yalbrinda shear zone, no reactivation of the Yarlbrinda shear zone in the south is apparent in the batholith. The renewed investigation of the Kondoolka batholith is related to recent remapping of the area in the light of improved geophysical data. A review of the radiometric data, as part of preparing a state wide grid, discovered a geology boundary that incorporated two different granite units under the same unit in the historic mapping. Several other features were also identified as part of the reinvestigation of the batholith including a potential fault incorporated into the current geophysical interpretation for the map sheet. A multidisciplinary approach was taken, geologist and geophysicist working together in the field and the office to better understand the Kondoolka batholith
