The PESA SA/NT Branch has played a drum roll and announced the winners of the Branch’s two research prizes for 2021.
The 2021 NTGS / PESA Student Prize for the best NT-focussed and energy-related thesis or paper has been awarded to Darwinaji Subarkah for his paper titled Unraveling the histories of Proterozoic shales through in situ Rb-Sr dating and trace element laser ablation analysis.

The paper was published in Geology in September 2021 and is reportedly the first work anywhere in the world where the deposition age of shales have been successfully retrieved using a novel laser-based reaction cell mass spectrometry technique.
In addition, the 2021 DEM-Cooper Energy-PESA Prize for the best SA-focussed and energy-related thesis or paper has been awarded to Monica Jimenez-Lloreda for her extended abstract and associated APPEA presentation Controls on gravity-driven normal fault geometry and growth in stacked deltaic settings: a case study from the Ceduna Sub-basin. The extended abstract was published in the APPEA Journal in July 2021 and Monica also presented her work at a PESA SA / NT Branch Technical Lunch in late 2021.
