Son calcaire correspond au Jurassique sup\u00e9rieur ou Malm, soit entre 161.2 \u00b1 4.0 \u00e0 145.5 \u00b1 4.0 Ma. Plus pr\u00e9cis\u00e8ment suivant les endroits, il s&rsquo;agit des \u00e9tages du Tithonien, anciennement Portlandien (150,8 \u00b1 4 &#8211; 145,5 \u00b1 4 Ma) ou du Kimm\u00e9ridgien (155,7 \u00b1 4 &#8211; 150,8 \u00b1 4 Ma). Cette formation g\u00e9ologique pr\u00e9sente un paysage au doux relief. Les ondulations peu prononc\u00e9es sont entrecoup\u00e9es de vallons \u00e9vas\u00e9s o\u00f9 s&rsquo;\u00e9coulent des rus pour rejoindre l&rsquo;Aire ou la Cousances. Dans \u00ab\u00a0l&rsquo;Herborisations de l&rsquo;Argonne\u00a0\u00bb, le docteur George Beauvisage d\u00e9crit ainsi le changement g\u00e9ologique argonnais : \u00ab\u00a0A cette diff\u00e9rence g\u00e9ographique correspond exactement une importante diff\u00e9rence g\u00e9ologique entre ces deux r\u00e9gions de l&rsquo;Argonne. Entre l&rsquo;Aisne et l&rsquo;Aire, on est sur le cr\u00e9tac\u00e9 inf\u00e9rieur ; les hauteurs de la for\u00eat d&rsquo;Argonne sont form\u00e9es par l&rsquo;\u00e9tage de la craie tufau (gaize et gr\u00e8s vert sup\u00e9rieur) et la Biesme coule sur le gault. De l\u00e0, toutes ces couches se relevant vers l&rsquo;est, on voit affleurer successivement dans cette direction le calcaire portlandien, sur lequel coulent l&rsquo;Aire et la Cousance, les marnes kimm\u00e9ridgiennes dans le fond de la vall\u00e9e du ruisseau de Wadelaincourt\u00a0\u00bb<sup>2<\/sup><\/p>\n\n\n\n<figure class=\"wp-block-image is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"550\" height=\"367\" src=\"https:\/\/argonne.jlfrance.fr\/wp-content\/uploads\/2026\/10\/calcaire-meuse-20227.jpg\" alt=\"Calcaire meuse 20227\" class=\"wp-image-287\" style=\"aspect-ratio:1.4986376021798364;width:550px;height:auto\" srcset=\"https:\/\/argonne.jlfrance.fr\/wp-content\/uploads\/2026\/10\/calcaire-meuse-20227.jpg 550w, https:\/\/argonne.jlfrance.fr\/wp-content\/uploads\/2026\/10\/calcaire-meuse-20227-300x200.jpg 300w, https:\/\/argonne.jlfrance.fr\/wp-content\/uploads\/2026\/10\/calcaire-meuse-20227-500x334.jpg 500w\" sizes=\"(max-width: 550px) 100vw, 550px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Except\u00e9 \u00e0 l&rsquo;ancienne carri\u00e8re d&rsquo;Aubr\u00e9ville ou en bordure de la D20 entre Ipp\u00e9court et Vadelaincourt et de la D21 entre Julv\u00e9vourt et Ipp\u00e9court, peu de zones d&rsquo;affleurement permettent d&rsquo;observer le calcaire en Argonne meusienne.
