Cratón
Is éard is cratón ann ná (Gréigis: κράτος kratos neart) áit ársa agus chobhsaí de chuid na mór-roinne litisféarach, ina mbíonn an litisféar comhdhéanta den dá sraith is uachtaraí den Domhain, an screamh, agus an mhaintlín uachtaireach.
Go minic, i ndiaidh timthriallta de nascadh agus scoilteadh a n-ilchríoch, bíonn cratóin go ginearálta le fáil ar an taobh istigh de na plátaí teicteonacha. is iondúil go mbíonn siad comhdhéanta de sean bonnlach criostalach, a d'fhéadfadh a bheith clúdaithe le charraig dhríodair níos óige. Bíonn screamh tiubh agus fréamhacha doimhne litisféaracha acu, a leathnaíonn a oiread agus cúpla céad ciliméadar isteach sa mhaintlín.
