Spain

Juan C. Larrasoaña is a geologist specialized in the application of palaeomagnetic techniques to a wide range of studies in Earth Sciences. One of his research interests is the magnetostratigraphic dating of fossil-bearing marine and continental successions, which provides the basis for interpreting the palaeontological record in terms of evolutionary changes. Since 2009, Juan C. Larrasoaña is a staff scientist in the Zaragoza headquarters of the Spanish Geological Survey (IGME).
