it is best to define the area of core loss as the interval heading. For example:
99.4. to 101.6: No Recovery. Interpreted to be intensely fractured zone. Drillers reported blocking off, core probably ground up during drilling.
103.4 to 103.7: Open Joint?. Drillers reported 0.3-ft drop of drill rods during drilling and loss of all water. Joint surfaces in core do not match.
0.7 to 11.6: Silty Sand. Poor recovery, only 6.2 ft recovered from interval. Classification based on recovered material and wash samples.
0.9 to 3.2: Rockbitted. No samples recovered. (Usually this would be subheaded under a previous description, inferring the materials are the same as the last recovered).

Notes to answerer
Asker: bonsoir, je viens de lire un article disant que la diaclase est une sorte de fissure, or fissure se traduit aussi par joint, je me demande s'il y a un moyen d'être certain qu'on parle bien de la diaclase et pas d'un joint, d'une fissure.
