\nLe boudinage<\/strong> est une structure tectonique ductile form\u00e9 par allongement\/\u00e9tirement<\/u>. Cela se forme lorsqu\u2019il y a un contraste de r\u00e9sistance entre niveau comp\u00e9tent et niveau incomp\u00e9tent.\n<\/p>\n<\/div>\n\n\n\n

\nLa roche<\/a> est une alternance de banc calcaire (gris clair) et marneux (marron). Les strates grossi\u00e8res ont \u00e9t\u00e9 \u00e9tir\u00e9es pour former des boudins marneux (d\u00e9formation ductile).\n<\/p>\n\n\n\n
