Comments |
---|---|---|
Coherent with silt laminae | 125.80–142.00 | Laminated clay couples with black mottled bands and silt laminae |
MTD 2-1 | 142.00–145.82 | Folds and small-scale normal faults; homogenized zone at the base |
Coherent with silt laminae | 145.82–151.40 | Laminated clay couples with black mottled bands with silt laminae |
MTD 2-2 | 151.40–154.83 | Recumbent folds and small-scale normal and reverse faults; homogenized zone in the upper and lower part |
Homogenized zone | Homogenized, relatively soft interval; transitional zone to coherent layers in the lower part | |
Coherent layers | Laminated clay couples with black mottled bands with silt laminae | |
MTD 2-3 | 173.34–180.1 | Several-meter-scale folds; homogenized zone in the lower part |
180.1–183.6 | Laminated clay couples with black mottled bands | |
MTD 2-4 upper | 183.6–188.67 | Inclined layers; recumbent folds are shown by faint dark mud laminae |
MTD 2-4 middle | Slightly inclined (–10°) layers; a few microscale normal faults; no recumbent folds or homogenized zone | |
