Le tephra (t\u00e9phra) de Rocourt est un niveau de retomb\u00e9es volcaniques, qui recouvre une bonne partie de la Belgique (Rocourt est une localit\u00e9 belge) (Juvign\u00e9, 1993), dat\u00e9 entre 78\u00a0000 et 80\u00a0000 ans.

Deux localit\u00e9s sources possibles\u00a0avaient \u00e9t\u00e9 propos\u00e9es : Dreiser Weiher et Pulvermaar, situ\u00e9s dans l\u2019Eifel ouest. Mais ceci ne semble pas correspondre \u00e0 la r\u00e9alit\u00e9. En effet le tephra de Rocourt est caract\u00e9ris\u00e9 par la pr\u00e9sence d\u2019orthopyrox\u00e8ne et d\u2019amphibole en grande quantit\u00e9 ce qui n\u2019est pas le cas de Dreiser Weiher et Pulvermaar. Inversement, ceux-ci contiennent des olivines et des clinopyrox\u00e8nes calciques (fassa\u00eftes) inconnus \u00e0 Rocourt.<\/p>\n
