International audienceIn this paper, we study the singular minimal foliation by the fibres of harmonic morphisms due to Burel from into where is a family of conformal metrics on . The map arises from a composition of a map to followed by a mapping of Hopf invariant kl. Regular fibres determine a foliation by minimal surfaces which becomes singular at critical points. In order to study the singular set we introduce a notion of multiple fibre and apply 4-dimensional intersection theory
