Biography

I am a keen and highly motivated young geologist with extensive training from both academic and industry environments. Throughout my university years and up to my present career in industry, I have focused on courses and research topics pertaining to ore geology, structural geology, geochemistry, mineralogy and geological mapping techniques.

In June 2016 I have graduated the master program "Evaluation of Sedimentary Basins and Mineral Resources" at the University of Bucharest, Faculty of Geology and Geophysics. During the master project I had the opportunity to work in collaboration with the Exploration department of the Boliden Mineral A.B. mining company on the Petiknäs North VMS deposit in Northern Sweden. The aims of the project were to describe the stratigraphic model of the deposit, the alteration halos and to generate geological, geochemical and alteration vectors to ore. The conducted work included: the remapping of the stratigraphy, alteration and mineralization from drill cores both within and outside the ore deposit and studies of physical volcanology, petrography, ore mineralogy and lithogeochemical techniques.

As for my industry experience, I have worked more than one year as a project geologist doing geological mapping for a company that is providing geological studies for large infrastructure projects. Moreover, I have also worked in the mining industry as an exploration geologist for Porphyry Copper deposits in SW Romania.

I came to Leeds in October 2017 for my PhD program. Here, I will broaden my knowledge in structural geology, geochemistry and ore deposits and I will try to understand the feedback relationships between the structural featrues and the geochemical changes associated with fluid transport in orogenic gold deposits.

Project details

Project title

Mineralized veins: How did they get there? A combined physiochemical approach to vein formation

Supervisors

Dr Taija Torvela and Dr Rob Chapman

Funding

Leeds Doctoral Scholarship

Start date

1 October 2017

Project outline

The propose study will use both geochemistry and structural techniques to study the genesis of hydrothermal mineralized veins in gold deposits from the Caledonides of Ireland, Scotland, and N. America. The project will characterise the paragenesis and geochemistry of mineralized veins and their associated alteration which may then be mapped into a structural evolution model.

The project aims to address two key knowledge gaps:

  • Scaling: what is the relative importance of fractures of various dimensions and connectivity as traps for mineralizing fluids?
  • Integration: what are the feedback relationships between structural features (stress and damage) and lithological/chemical changes associated with fluid transport?
