The age of undeformed dacite intrusions within the Kolaka Fault zone, SE Sulawesi, Indonesia

White, Lloyd; Hall, Robert; Armstrong, Richard

Description

We present petrologic, geochemical and U-Pb sensitive high resolution ion microprobe (SHRIMP) data from previously undocumented dacite intrusions from the SE Arm of Sulawesi. The dacites occur in a strand of a major fault (the Kolaka Fault) that crosses the SE Arm of Sulawesi and northern Bone Bay. U-Pb SHRIMP dating shows the "Kolaka Dacite" yields zircon grains and overgrowths that range between ca. 4 and 7. Ma, indicating active magmatism in SE Sulawesi at this time. The youngest age...[Show more]
