The sedimentary and tectonic evolution of the Bangemall Basin Western Australia and implications for mineral exploration

Summary

The middle Proterozoic Bangemall Group is subdivided into three vertically juxtaposed subgroups which reflect major phases of the basin’s tectono-sedimentary evolution.

The distribution of sedimentary environments in time and space was controlled by regional tectonic events, and shows a cyclic pattern.

The evolution of the basin shows similarities to that of failed rifts.
