3-year Postdoc in Geochronology

3-year post-doc fellowship in geochronology with focus on fractured and weathered basement on and offshore Norway.

Applications are invited for one post-doc position within the Norwegian Research Council (RCN) project “BASE – Basement weathering and fracturing on- and offshore Norway”.

The position is available from January 2022, has a duration of 36 months and is based at NGU in Trondheim.

Research Project BASE aims to gain new geological (subsurface) understanding of fractured and weathered basement rocks on- and offshore Norway. Largely relying on recently drilled onshore basement wells and existing offshore shallow boreholes, we will improve the current understanding of offshore unconventional crystalline basement plays, while also further strengthening the correlations between the off- and onshore domains. BASE addresses the following key question for which we are inviting applications from early-career scientists in the field of low-temperature geochronology.

Post Doc Project: When and how long were the main periods of crustal stability, resulting in peneplanation and deep weathering?

The aim of the project is to constrain when basement rocks in key target areas in Norway were undergoing periods of extended crustal stability and peneplanation resulting in deep weathering, and periods of exhumation, by applying several low temperature geochronological and thermochronological methods.

NGU hosts state of the art K-Ar and 40Ar/39Ar laboratories for clay minerals, mineral separates and in-situ 40Ar/39Ar analyses, in addition to 3 LA-ICP-MS instruments. We wish to upgrade our Apatite Fission Track analytical capabilities with in-situ laser-ablation ICP-MS analyses of U and trace element concentrations in apatite and combine fission track counting and track length data with contemporaneous acquisition of apatite U-Pb data. These data will be combined with other thermochronological methods to resolve the long-term thermal histories of the study areas.

We seek a post-doctoral geoscientist with documented skills on method development using the LA-ICP-MS and a strong research interest in thermochronology to develop our laboratory and collect thermochronological data. Previous experience with fission track analysis is beneficial but not required.

The successful candidate should preferably have a background in Earth Sciences, ideally with experience in crystalline basement geology, LA-ICP-MS analyses and low-temperature geochronology. Experiences in the use of Geographical Information Systems (GIS), and visualization tools are desirable for the position. Good laboratory skills are beneficial. Applicants must have completed their Ph.D. education at the time the position starts.

NGU offer a favourable working environment, unique scientific challenges, and good possibilities for international collaborations.

NGU wishes to have a diverse and inclusive work environment. We welcome all qualified applicants - regardless of, for example, age, gender, national or ethnic background, ability to function, or gaps in the CV.

Remuneration of the position will be according to the Government's main agreement on wages, as follows: Scientist with PhD degree (code 1109).

For further information, please contact project coordinators Jochen Knies (jochen.knies@ngu.no), Roelant van der Lelij (roelant.vanderlelij@ngu.no) and/or Head of The Laboratories Ida Noddeland (ida.noddeland@ngu.no).

The lists of applicants are publicly available information. Only in special cases will this information be held back.

NGU is Norway’s geological survey. We map national geology, and disseminate and present data in order to meet society’s needs for basic geological knowledge. NGU is owned by the Ministry of Trade, Industry and Fisheries. Our mission and activity are designed to stimulate added value and sustainable economic growth.
