The University of Plymouth, United Kingdom, invites applications for a 3.5-year PhD studentship in Geological Sciences, focusing on the project "Hot rocks and hidden metals: The porosity puzzle of the Cornubian batholith." This research will investigate the porosity and mineralization processes within the Cornubian batholith, a significant geological formation in the UK known for its metal resources. The project is part of the ARIES Doctoral Training Partnership, offering advanced training and research opportunities in geology and earth sciences. Supervised by Professor Nazrul Khandaker, the successful candidate will join a vibrant research community at the University of Plymouth. The project will involve fieldwork, laboratory analysis, and data interpretation related to mineralogy, petrology, and geochemistry. The research aims to enhance understanding of subsurface porosity and its implications for metal resource exploration and extraction. The studentship is funded for 3.5 years, typically covering tuition fees and providing a stipend for living expenses in line with UKRI rates. Applicants should hold a strong undergraduate degree (2:1 or above) or a relevant master's qualification in geological sciences or a closely related field. Experience or interest in mineralogy, petrology, or geochemistry is desirable. English language proficiency may be required for non-native speakers. To apply, candidates should use the University of Plymouth's online application portal, selecting the ARIES Doctoral Training Partnership studentship for Geological Sciences. The application process requires submission of academic transcripts, references, and other supporting documents as specified on the university website. The studentship will commence on 1 October 2026, and the application deadline is 1 October 2026. For more information and to apply, visit the project page or use the provided application link.
