100%, Zurich, fixed-term

The Institute of Geochemistry and Petrology at the Department of Earth Sciences of ETH Zurich invites applications to undertake a fully funded PhD (4 years) on the timescales of magmatic and volcanic systems. Magmatic systems tend to incrementally grow over protracted periods of time. However, certain magmatic systems, including melt extraction zones, subvolcanic systems and associated ore deposits offer ideal conditions for the growth of minerals several orders of magnitude faster than traditional growth rates as a consequence of significant cooling- or decompression-driven undercooling. A promising method to constrain the growth rate of minerals relies on the in-situ analysis of stable isotopes, as these are expected to fractionate during rapid crystal growth.

Job description

You will perform high-temperature experiments simulating the growth of minerals at relevant magmatic conditions. You will develop SIMS analytical protocols and determine the kinetic fractionation of stable isotopes as a function of mineral growth rates. High-resolution in-situ analysis of natural magmatic minerals from variety of volcanic and plutonic environments will allow to constrain subvolcanic processes occurring on short magmatic timescales. Although some experimental or analytical experience is desirable, a keen interest in using a multifaceted approach to characterize petrological and geochemical processes is most important. You are expected to fulfill some laboratory and/or teaching duties. Reviewing the applications will start early October, the position will be filled once a suitable candidate is found. The position is available in early 2022, the annual salary is according the ETH standards .

Your profile

• Master degree (or equivalent) in Earth Sciences
• Strong interest in geochemistry, igneous petrology, numerical modeling
• Knowledge of experimental petrology is an advantage but not a requirement
• Motivated at targeting scientific problems from a multidisciplinary perspective
• Strong motivation to carry out high-temperature and high-pressure experiments
• Enthusiasm for working independently and in a collaborative and structured manner
