Mount Newman
Australia
The Mount Newman experience has shown that spectrometry can be used to trace marker layers within a faulted iron formation.
 |
Mount Newman, in Australia, is an iron deposit within a banded Iron formation (BIF). |
 |
A borehole spectrometric survey was completed to aid stratigraphic correlation. A total of 5 logs were recorded allowing units to be traced over a distance of 300 km. |
|
Results show that not all shale layers produce a strong gamma-ray response, but several are distinct markers, which enable stratigraphic correlation. |
