We will investigate the geometry of rational equivalence classes of points on a surface  . We will show that if   is a general projective K3 surface then these equivalence classes are dense in the complex topology. We will also show that if   has the property that these equivalence classes are Zariski dense, then  . To cite this article: C. Maclean, C. R. Acad. Sci. Paris, Ser. I 338 (2004).
