ARCEx congratulates PhD fellow Tore Aadland at the Department of Geosciences, University of Bergen, for successfully defending his PhD thesis titled “Disentangling time from siliciclastic sedimentary rocks”.

Dr. Aadland was supervised by Prof. William Helland-Hansen, UiB, and Snorre Olaussen, UNIS.

In his project, Tore investigated the amount of geological time that has been preserved in the stratigraphic rock record. He has worked on the topic by deriving mathematical models describing how quickly sediments have been deposited over geological time, and by analyzing satellite images from the last 30 years to find empirical models that calculate the migration rate of modern coastlines dominated by river deltas.

The work outlines a new methodology for the analysis of sedimentary rocks using data from these modern coastlines to understand how long it has taken to deposit sediments in deep geological time.

This can give us a better understanding of the spatial dimensions and depositional history of sedimentary packages and the filling history of sediment basins that could potentially contain oil and gas-bearing sediments.
