  We establish the existence of semiclassical states for a nonlinear
Klein-Gordon-Maxwell-Proca system in static form, with Proca mass 1 on a closed
Riemannian manifold.
  Our results include manifolds of arbitrary dimension and allow supercritical
nonlinearities. In particular, we exhibit a large class of 3-dimensional
manifolds on which the system has semiclassical solutions for every exponent
p>2. The solutions we obtain concentrate at closed submanifolds of positive
dimension as the singular perturbation parameter goes to zero
