Bas de la coupe de gauche. La formation gris-bleu basale est le fantôme de roche en place. On y distingue les fins filons de calcite subverticaux qui témoignent de l’altération in situ de la roche mère. Au-dessus, la formation est un limon argileux ravinant le fantôme de roche.
Bottom part of the left section. The grey bottom formation is the non-removed ghost-rock. One can see thin calcite vertical joints which are the witnesses of the in situ weathering of the bedrock. To the top, the clayed loamy formation is incising the ghost-rock.
