After all observations are made, a mudstone may be described, for instance, as a “gray, moderately bioturbated, discontinuous wavy-nonparallel-laminated, calcareous medium mudstone with abundant foraminifera and sparse pyrite nodules.” The same rock can be also referred to using a shortened, readily usable phrase such as a “bioturbated, calcareous medium mudstone.” We recommend the use of such phrases only after the variability in the studied mudstone succession has been fully characterized. | After all observations are made, a mudstone may be described, for instance, as a “gray, moderately bioturbated, discontinuous wavy-nonparallel-laminated, calcareous medium mudstone with abundant foraminifera and sparse pyrite nodules.” The same rock can be also referred to using a shortened, readily usable phrase such as a “bioturbated, calcareous medium mudstone.” We recommend the use of such phrases only after the variability in the studied mudstone succession has been fully characterized. |
