Till genesis

The project is associated with a larger project, financed by Formas. The aim is to study the physical composition of the till and see if and how there is a couple to bedrock properties. The project studies till from all different aspects. Two test areas associated with rock quarries have been studied in detail, one at Olunda near Uppsala, and one at Bäckseda near Vetlanda. Several geophysical tests have been made over a test area of till at each site. This includes georadar, resistivity, magnetic susceptibility, VLF and seismic. The total size distribution and lithological composition of the clasts has been studied at each site, from either sections or sample pits. The size distribution and the composition of the clasts are determined.
The aim of this x-job is to study the till in sections at these two sites with respect to till genesis. The present study of size distribution of the till is restricted to the geophysical test area. There are numerous sections around the rock quarry in several different orientations. All the sections need to be described in detail with respect to sedimentary structures and fabric analysis need to be done. The results of the sections can then be coupled to the existing data from the geophysics, and total size and shape distribution and petrographic analysis. Based on both the study of the sections and the previous data a model for the till genesis is to be made and related to the glacial history of the area.
The project requires good knowledge of Quaternary Geology.
The advisor of the project is Docent Joanne Fernlund. You will also work in close cooperation with other master students working on associated projects and well as doctorate student Mimmi Arvidsson responsible for the geophysical studies.
