Description

Lund University, Faculty of Science, Department of Geology

Lund University was founded in 1666 and is repeatedly ranked among the world's top 100 universities. The University has around 44 000 students and more than 8 000 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.

Lund University welcomes applicants with diverse backgrounds and experiences. We regard gender equality and diversity as a strength and an asset.

Subject description It is widely recognized that the expansion of silica biomineralization in the oceans has affected the evolutionary competition for dissolved Si. There is a widely accepted idea that the appearance of siliceous organisms contributed to a marine DSi decline in the late-Precambrian/early Phanerozoic, based largely on inferences from chert petrology, but direct evidence for this event is missing. The Ediacaran-Cambrian is a critical period when the earliest siliceous fossils (siliceous sponges and radiolarians) are recorded, accompanied by fluctuations in marine redox conditions, terrigenous inputs, climate and biological innovations. The aim of this project is to explore the silicon cycle evolution through the Ediacaran-Cambrian periods and its interaction with other geological/biological processes.

Work duties The main duties involved in this post-doctoral position is to conduct research. Teaching may also be included, but no more than 20% of working hours. The position shall include the opportunity for three weeks of training in higher education teaching and learning.

  • Investigate changes in reverse weathering intensity during the late- Precambrian/early Phanerozoic.
  • Use scanning electron microscope applying SEM-EDS) to determine elemental composition.
  • Measure C, S, Si, Sr, and O isotopes and mapping with Raman spectroscopy.
  • Investigate the preservation of sponge silica from different sediment archives.
  • Writing manuscripts.
  • Administration related to the work duties listed above.
  • Qualification requirements Appointment to a post-doctoral position requires that the applicant has a PhD, or an international degree deemed equivalent to a PhD, within the subject of the position, completed no more than three years before the date of employment decision.

  • Very good oral and written proficiency in English.
  • Determine clay mineralogy using scanning electron microscope (SEM) and with electron backscatter diffraction (EDS).
  • Measure C, S, Si, Sr, and O isotopes to investigate geological process
  • Experience in working with samples from marine sediment archives.
  • Knowledge to connect variation in biomineralisation of organisms with the biogeochemical changes in the environment.
  • Assessment criteria and other qualifications This is a career development position primarily focused on research. The position is intended as an initial step in a career, and the assessment of the applicants will primarily be based on their research qualifications and potential as researchers.
