The *Isotope Geochemistry Group *of the Institute for Geochemistry and
Petrology invites applications for a PhD position to explore the Mg and Sr
stable isotope signature in evaporitic sequences.

The project includes a study of modern and ancient evaporites via
experiments, fieldwork, and laboratory analyses of natural samples. It is
aimed at developing new archives for seawater isotope composition of Mg and
stable-Sr and at using these archives to reconstruct past variations in
these isotope compositions of the ocean.

*Project background*

In recent years, the oceanic balance of Mg and stable-Sr isotopes (as δ26Mg
and δ88/86Sr values) has been investigated, demonstrating their
potential to trace past variations in the oceanic inputs and outputs of
these elements. However, the scarcity of past seawater δ26Mg and δ88/86Sr
record data, and differences between existing data-sets (all based on
Ca-carbonate archives), currently limit this approach. In this project, we
will explore and develop new evaporitic (non-Ca-carbonate) archives for
seawater δ26Mg and δ88/86Sr values and use them to reconstruct past
variations in seawater composition. In that framework, we will also study
the environmental conditions related to the formation of these evaporitic
sequences as well as their post-depositional preservation.

*Job description*

The position is funded for four years by the Swiss National Science
Foundation. It includes mainly geochemistry laboratory work as well as two
field trips for sampling (in Italy and Israel), sedimentary and
petrological study of the sequences, data analysis and modeling and
outcomes communication (in conferences and papers). The position offers the
student an excellent training in a world-leading Earth’s surface group and
laboratory as well as collaborations with geoscientists from different
countries.

*Your profile*

We seek an excellent team-oriented candidate with an MSc or equivalent
degree in Earth science or in other related natural sciences (e.g.,
oceanography, chemistry), and a strong motivation to work in the
laboratory. Very good communication and writing skills in English are
required. Experience in geochemical laboratories and/or mass spectrometry
and/or with evaporitic systems will be of advantage.

*ETH Zurich*

ETH Zurich is one of the world’s leading universities specialising in
science and technology. We are renowned for our excellent education,
cutting-edge fundamental research and direct transfer of new knowledge into
society. Over 30,000 people from more than 120 countries find our
university to be a place that promotes independent thinking and an
environment that inspires excellence. Located in the heart of Europe, yet
forging connections all over the world, we work together to develop
solutions for the global challenges of today and tomorrow.

*Interested?*

We look forward to receiving your online application with the following
documents: CV, motivation letter, course grades and transcripts, and the
names and email addresses of 1-2 referees. An online interview may be
required in later stages. Please note that we exclusively accept
applications submitted through our online application portal. Applications
via email or postal services will not be considered.
