摘要：The new chances offered by elementary particles as probes of the internal structure of our planet are briefly
reviewed, by paying particular attention to the case of high energy neutrinos. In particular, the new results
concerning the shadow of mountains on ντ flux at Pierre Auger Observatory is briefly discussed, and moreover
the possibility to use the tail of atmospheric neutrinos to probe the core/mantle transition region is just sketched.
