Short biogaphy:

Ana did her BSc (1998), MSc (crystallography/mineralogy/metallogeny-2002) and PhD (metallogeny-2011) at the Faculty of Sciences of Lisbon University, Portugal (FCUL). Her postgrad research focused on ore-forming systems associated with igneous layered intrusions, their petrogenesis and tectono-magmatic evolution. Between 2009-2013 she was invited Assistant Professor at the Geology Department of FCUL and research consultant for the mining industry. She started working in GUtech in 2014 and develops metallogenic and petrogenetic investigation at multiple levels of the Samail Ophiolite of Oman…

  • Petrogenesis of ophiolites, particularly mid and lower crustal gabbroic rocks.

Research Projects

  • Project title: Oman Drilling Project
    Period: 01/2015–12/2018
    Role: Co-investigator
    Funded by: International Continental Drilling Program
    Porject description:

    The Oman Drilling Project is a multi-national collaboration aimed at understanding the oceanic crust and mantle, carbon cycling in subduction zones and modern day carbon capture and its interactions with the hydrological cycle. A comprehensive drilling program is underway in the Semail Ophiolite, the largest and best exposed section of oceanic lithosphere in the World, collecting rocks, water, geophysical data and microbiological samples.
    I worked as staff scientist and liaison person between GUtech and the Project direction since January 2015. On-site scientific team between 8 January -5 February 2017 (Drill sites GT1, GT2). Shipboard party scientific team member aboard Deep Sea Drilling Vessel Chikyu for core logging 15 August-15 September 2017.

  • Project title: Esmeralda Vasco da Gama Shipwreck
    Period: 06/2013–09/2016
    Role: Co-investigator
    Funded by: Oman Ministry of Heritage and Culture
    Porject description:

    Consulting geologist of technical and scientific team that worked for the identification of the recovered historical artefacts. Provenance analysis of stone cannonballs.
