PhD: Testing the impact vs. volcanic hypotheses for mass extinctions
Applications are invited for a PhD fellowship/scholarship at Graduate School of Natural Sciences, Aarhus University, Denmark, within the Geoscience programme. The position is available from 1 February 2021 or later. Application deadline 1 November 2020 at noon (11.59 AM CEST).
Testing the impact vs. volcanic hypotheses for mass extinctions
Research area and project description:
This Ph.D. focuses on testing the possible causes of mass extinctions in the geological record. Mass extinctions are catastrophic biological turnovers showing losses of up to 80% of all species. There are essentially two competing hypotheses to explain such severe stress on marine and terrestrial global ecosystems: extraterrestrial impact and large-scale volcanism. In this research project the Ph.D. student will address these hypotheses mainly through geochemical analyses and interpretation of sedimentary records of mass extinction intervals and in associated magmatic rocks of large igneous provinces. Altogether these geochemical records of volcanic or extraterrestrial forcing will be related to proxies for ecosystem turnover. Initially, this project will focus on sedimentary records of the end-Triassic mass extinction and the possible relationship to the Central Atlantic Magmatic Province. Other mass extinction intervals will also be included.
The position is funded by the Independent Research Fund Denmark (DFF) and the work will be carried out in an international research environment.
Qualifications and specific competences:
The PhD candidate must have a M.Sc. (for the 3-year PhD programme) or 4-years of studies (for the 4-year PhD programme) in Geoscience. A candidate with experience in analytical geochemistry is preferred. Further experience with igneous, sedimentary or extra-terrestrial rocks, large igneous provinces, or mass extinction intervals in the sedimentary record are considered advantageous, but not required.
Place of employment and place of work:
The place of employment is Department of Geoscience, Aarhus University, Høegh-Guldbergs Gade 2, DK-8000 Aarhus C, Denmark. The research will also involve the Geological Survey of Denmark and Greenland.

Before you apply
Information and attachments:
Please be aware that you must have all relevant appendices, attachments, addresses for referees, etc. ready when you apply, as the entire application must be uploaded to the system in one go.
Documentation of language skills:
The English language requirement at the graduate school is comparable to an "English B level" in the Danish upper secondary school ("gymnasium").
English language qualifications comparable to an "English B level" are documented by one of the following tests:
When to take the test and how to upload the documentation:
The test result must not be more than two years old at the time of application.
The English language test should be taken before applying for admission and uploaded under "language skills documentation" in the online application form.
It is possible to apply for admission before you have taken the test. In this case documentation stating that you have signed up for a test (please state expected submission date) must be uploaded. If the test result is not part of the original application the test result is to be sent to email@example.com no later than one month after the application deadline.
The following applicants are exempted from documenting their English qualifications/taking a test:
The programme committee may request further information or invite the applicant to attend an interview.
