The possibility to observe matter effects in neutrino oscillations from initial muon neutrinos is discussed for Earth baselines. The physics of the problem suggests a no-go theorem. The way out to this is found. A magnetized iron detector for baselines above 7000 Km can detect fake CPT odd asymmetries for the survival probabilities of neutrinos and antineutrinos. The asymmetry is sensitive to both the sign of the neutrino mass difference and the connecting mixing (1,3) between solar neutrino and atmospheric neutrino sectors.
