Abstract
Numerical integrations in the frame of Sun-Mars-Jupiter-Saturn model over 1Myr have been performed in order to investigate the orbital evolution of asteroid fragments produced in the innermost asteroid belt (2.07–2.13AU). Fragments injected in the vicinity of the V6 secular resonance enhance their eccentricities and become Mars-crossers. Close encounters to Mars will then lead to a random walk in semi- major axes. Two different mechanisms may occur to produce Earth-crossers. In the first case, the fragment enters the 4/1 mean motion resonance and becomes an Earth-crosser within at least 2.6 * 105 years. In the second case, which involves only the secular resonance V6 the shortest timescale for deriving meteorites is of the order of 5.6 * 105years.
