3-3-3-3-3-3-3-3-3-3-3-3-3 From: "LLEWELLIN, EDWARD W." <ed.llewellin@xxxxxxxxxxxx> Dear All, We invite applications for a Postdoctoral Research Associate (PDRA) to join the Department of Earth Sciences at Durham University as part of the project â??Multi-scale investigation of rheology and emplacement of multi-phase lavaâ??. The project is funded jointly by the UKâ??s Natural Environment Research Council and the USAâ??s National Science Foundation, and involves collaboration among Prof Ed Llewellin (Durham), Dr Einat Lev (Lamont-Doherty Earth Observatory, University of Colombia), Prof Alan Whittington (University of Texas at San Antonio), Prof Julia Hammer (University of Hawaii), and Dr Hannah Dietterich (USGS). The Durham component of the project will undertake laboratory investigation of the rheology of two- and three-phase analogue lavas, as an integral part of the broader study, which focusses on the emplacement of lavas during the 2018 eruption of the Lower East Rift Zone (LERZ) of Kilauea, Hawaii. Analogue suspensions of bubbles and rigid particles in Newtonian liquids will be prepared and their rheology characterized using Durhamâ??s state-of-the-art rheometry suite. The successful applicant will undertake two broad suites of experiments: 1. Textural characteristics will be matched to the range of natural textures from the LERZ eruption, and a bespoke model for the evolving rheology of the LERZ lavas will be developed. Results will feed into numerical models for emplacement of the LERZ lavas. 2. A general and fundamental study of the rheology of multiphase suspensions with bubble and particle fractions in the mid-range. This is the range that is most relevant to flows of lava and magma, but is currently poorly understood. The successful candidate will work with members of the international project team to integrate rheological results within the broader study.
