En JOurs) 1,27· 10~-loglo 1 (8) Quelques valeurs de v et t en fonction de a sont donnees dans Ie Tableau II et representees sur la Fig. 1. Les mouvements de l'atmosphere peuvent modifier ces resultats dans certains cas, mais d'une fa90n generale on peut s'en servir dans la discussion des relations entre les essaims meteoriques et leurs influences dans la basse atmosphere. La majeure difficuIte des collectes terrestres est dans la separation correcte des composantes cosmique et terrestre. Un des criteres generalement admis et assez sensible est la presence du nickel.
Les memes carrotages ont fourni quelques informations sur les spherules magnetiques [10]. 10-17 gcm- 2sec- 1 en spherules bien entendu. 44 P. LINK: b) Les filtrages de l'air aux iles de Hawaii par PETTERSON [11] ont ete efi'ectues a l'altitude de 3 km. Les resultats sont positifs dans 29 de 31 cas en ce qui concerne la presence de nickel. La microanalyse a donne les resultats moyens suivants Ni 14,3· 1O- 15g cm- 3 Fe 1577· 1O-15g cm- 3 On a donc Ie rapport Ni:Fe=K o=0,9%. m. Pour en calculer l'accretion il faut connaitre la I vitesse de chute.
