Nanyang Technological University, Singapore* Dear colleagues and students, I am writing to advertise an exciting PhD opportunity at Nanyang Technological University in Singapore. The project will focus on charactersing pre-eruptive storage conditions and timescales of the 1815 Tambora eruption, Indonesia. This will involve: 1. Modelling trace element diffusion (Mg, Sr, Ba, Li) in plagioclase crystals from erupted pumice clasts and cumulate samples in order to determine timescales of pre-eruptive mixing, transport and storage. Diffusion profiles of Fe-Mg in clinopyroxenes may also be used as a complementary source of timescale information. 2. Tracking the evolution of volatile contents using apatite and melt inclusions. 3. Constraining magma storage depths using volatile contents of plagioclase and clinopyroxene-hosted melt inclusions, clinopyroxene-liquid thermobarometry and possibly phase equilibria experiments. 4. Assessing variations in final magma decompression rates by modelling the diffusion of water in clinopyroxenes and bubble number densities from different eruptive units. Applicants with a strong background and interest in volcanology, petrology and geochemistry are encouraged to apply. The initial deadline for the August 2024 intake is the *31st of January 2024.* More information about the PhD program can be found here: https://urldefense.com/v3/__https://www.ntu.edu.sg/education/graduate-programme/ase-doctor-of-philosophy-(phd)-(by-research)*additionaiInformation__;Iw!!IKRxdwAv5BmarQ!eWdh9eNsu18qh7mcYKRzGbZFWywzGuLsKxkOlZSyqYaBVHi5XuO1f8dRkqF-VvsX5E6AqfX9A2fhFxCG$ <https://urldefense.com/v3/__https://www.ntu.edu.sg/education/graduate-programme/ase-doctor-of-philosophy-(phd)-(by-research)*additionaiInformation__;Iw!!IKRxdwAv5BmarQ!br10URqePSEmzdToslYNU3BZFH3ZbWFLuqkA4N1rF8etPSjzNJz4HuxcgiEjBs7X1ZpB2G57KgCJH5Zk3bgbMQ$> Interested applicants please contact Dr. Euan Mutch (euan.mutch@xxxxxxxxxx) with copy of your CV for more information about the project and the application process.
