| Abstract: | The Maoming Basin is one amongst a group of Cretaceous-Tertiary basins in South China-347 samples were collected from drill
cores MR and MB and section MS (110° 54′ E. 21° 45′ N). Most of the lithological units are of Tertiary age. The cores include
the Laohuling. Shangcun, Huangniuling and Youganwo formations. The MR core (874m in length) has recorded the polarity history
from Normal Zone 18 to Normal Zone 11 on the Geomagnetic Polarity Time Scale (GPTS). The strata were formed from about 42Ma
to 32Ma, that is from Late Eocene to Early Oligocene. A mean sedimentation rate of this stratigraphic column is 8.1 cm/ka. |
