Covadonga Brime was worn on 26 September 1950 in the town of Oviedo, Asturias, north-west Spain. She achieved her degree in Geological Sciences in June 1973 from the University of Oviedo, was awarded her PhD in Sciences (Geology) on 26 May 1978 (Oviedo University) and received her ‘Proficiency in English’ (Cambridge University) in June 1978. In October 1975, she joined the ETSIMO (Higher Technical School of Mining Engineers of Oviedo). She worked there as an assistant professor from October 1975 until February 1983 and then at the Department of Geology (Oviedo University) until 13 January 1987, when she was promoted to Profesor Titular de Universidad (Associate University Professor) chair, which she held until she retired 25 years later on 22 June 2012 (Fig. 1).

Passionate about teaching and learning, Covadonga was an excellent, disciplined, punctual, modest and well-organized teacher (as good an educator as she was) and lecturer (as an expert in mineralogy). She was not a mineralogist in the traditional sense, however. In Covadonga's courses, which always carried her personal style, the themes of her carefully structured and first-rate lectures were updated continuously and developed to be as clear as possible. Her practical sessions focused mainly on helping the students with basic knowledge of minerals and rocks, not just studying minerals in a traditional fashion (using hand specimens and under the microscope) but also providing context in terms of the processes and environments in which the rocks and minerals were formed, the relationships between ore deposits, their geochemistry, magmatism and geodynamics, the analytical methods used to characterize them and their role in the natural and environmental sciences. She also provided practical sessions using computer programs in which students learned to analyse actual mineralogical data. Covadonga worked hard to make sure that both her theoretical and practical classes along with fieldwork were presented in perfect harmony.

Covadonga was keen that her graduate students learned not just the fundamentals of mineralogical research; she also focused on encouraging them to think critically (in science and in everyday life), to analyse complex mineralogical problems and to devise effective solutions, all valuable skills they would draw upon for the rest of their professional careers in either an academic or industrial environment. She also engaged students in activities or assignments that provided them with opportunities to practise or apply what they were learning in theoretical sessions. Her practical exercises were designed to provide the students with the knowledge and skills that support other courses throughout their degree course in geology. The exam questions she posed were based on the resolution of selected practical mineralogical problems and on writing assignments, which encouraged the students to keep up with required reading, to attend classes and practical sessions regularly and to make logical arguments based on the facts at hand. Her mineralogical seminars, which culminated in student presentations, and Covadonga's insightful comment on each one represented a collegial effort that her students remembered and appreciated after graduation, especially those who developed professional careers in laboratories, mines or in construction or extraction companies.

Appreciative of her influence on them, some of her students wrote warmly about Covadonga in their messages of condolence upon her passing away: ‘She made the subject of each lecture (e.g. the principles of thermodynamics, phase diagrams and mineral stability) so easy to understand!’ ‘She was super demanding but at the same time fair, accessible and an endearing person.’ ‘She rewarded effort well.’ ‘Some lecturers, e.g. Covadonga, have such an influence that their students never forget them.’ And ‘She was a woman who argued for equal rights for men and women in society and at work, and fought discrimination, whether negative or positive.’ Covadonga would have been delighted to read these messages.

In addition to her teaching and her relationships with her students, we must also make mention of the research work – so strongly related to her teaching – that Covadonga did, as well as the national and international collaborations and friendships that she maintained over many years and the many conferences and debates in which she participated (Fig. 2). From her debut on the international scene at the VI International Clay Conference held in Oxford in July 1978 until her retirement, Covadonga built strong international collaborations and mentored younger generations of geologists, passing on to them her interest in extending our academic knowledge and advancing analytical techniques. As the Spanish representative, Covadonga joined International Geological Correlation Programme (IGCP) No. 294 (1989–1993) on ‘Very Low-Grade Metamorphism’ (led by Professors Richard Bevins and Doug Robinson) and attended all of the meetings and field trips at select locations around the world. She was also a member of the ‘Illite Crystallinity Working Group’ (led by Professor Hannah Kish). Covadonga also served as the Chair of the Committee on Electronic Communications on behalf of The Clay Minerals Society (April 2010) upon invitation by the President, Dr Derek Bain.

Covadonga was widely known as an expert in the study of the processes and transformations in rocks during the early stages of metamorphic recrystallization and low-degree metamorphism all over the world, but especially in north-west Spain, eastern Austria and in the Carnic Alps (Austria and Italy). The following lists many of her collaborations throughout her career: with Susana García López, Mariluz Valín, Fernando Bastida and Jesus Aller she studied the tectonothermal evolution of the western nappes in the Cantabrian Zone (Variscan Belt of north-west Spain). Together with Jose Antonio Sáenz de Santa María, she worked on the low-grade metamorphism in the Asturian Central Coalfield (north-west Spain). She worked with the late John A. Talent and the late Ruth Mawson on the correlation between clay minerals and organic maturity indicators for the Silurian to Tournaisian of eastern inland Australia, and she studied thermal evolution in the Townsville Hinterland of north-eastern Australia. She worked with Robin Offler on low- and very-low-grade metamorphism in the Nambucca Block in the southern New England Fold Belt in eastern Australia. She collaborated with Enrique Estrada on clay digenesis in the San Jorge Gulf Basin (Argentina). Denny Eberl was her collaborator for work on the crystal-growth mechanisms of diagenetic low-grade illites determined using the shapes of crystal thickness distributions. Finally, she partnered with María Christina Perri, Monica Pondrelli, Claudia Spalletta and Corrado Venturini for work on the thermal evolution of the pre-Variscan sequence of the Carnic Alps (Austria and Italy).

All the while, Covadonga also managed to develop another of her passions: brachiopods (Fig. 3). With Fernando Alvarez and Gordon B. Curry, she conducted a comparative study of the structure (microstructure and composition) and growth of fossil and Recent Brachiopoda, taking their shells as an example of the controlled formation of biominerals. She also studied the variation in shell morphology and problems associated with the compilation of data matrices for phylogenetic analysis and the preparation of electronic databases.

She was invited to give two lectures, the first at Nanjing Academia Sinica (China) with the title ‘Geological Evolution of the Iberian Peninsula, Spain’ on 28 May 1992, and the second at Ruprecht Karls Universität, Heidelberg (Germany), with the title ‘Diagenesis in the Palaeozoic rocks of the Cantabrian Mountains, Spain’ on 2 December 1999. She attended 25 conferences in 11 countries, at which she presented 15 papers. She was an active member of 15 societies, of which four were Spanish. She made sabbatical visits at various universities and research centres around the world.

In 2012, Oviedo University awarded her a gold medal for her dedication to the institution.

Academic achievement is only part of the story, of course. Covadonga will be remembered as a jovial and very generous person, a strong woman but patient with her students, for her warmth and kindness, her ability to inspire, encourage and support, her willingness to give sound, considered advice when asked, her deeply held sense of ethics and integrity, with a sharp mind and a wonderful sense of humour, a love of irony and an ability to see the funny side of most things, who was a joy to work with in the lab and in the field. Covadonga, we will miss your smiling face around here!

Covadonga suffered breast cancer in 2011, lived with a pacemaker from 2016 onwards and, having been diagnosed with chronic lymphoid leukaemia in 2019, died in August 2022 at the age of 72.

To finish, I will copy here a beautiful wish in Irish that Kevin Murphy sent me just after Covadonga has departed this world:

Kevin also performed a detailed and very much welcome review of this appreciation.

I treasure the written tributes from graduate students and colleagues and the many happy memories that will sustain me at this difficult time.
