Project details

The goal of this project was to develop tectonic and isotopic models for the Musgrave Block. This is part of a broader program dealing with the Proterozoic tectonic evolution of the Australian continent. The underlying motivation is to provide a coherent integrated tectonothermal and isotopic framework. This project partly achieved this by:

1. Nd isotopic analysis of basal gneissic sequences in the Musgrave Block.

2. Creating a model of crust-mantle evolution through the crustal growth history of the Musgrave Block.

3. Determining age constraints on sequences within the Musgrave Block through Nd/Pb isotopic analysis.
