- Comments
- DdBq-VP, Romaines River: The silt enclosing the whale bone dated by S-3047 also enclosed marine shells dated to 12,800 +/- 130 BP (GSC-4858). Grant comments that "On one hand, and taking account of the error range, the shell and bone ages are in reasonable agreement, considering they derive from the same horizon, yet are on different materials. They are thus considered to corroborate one another. On the other hand, the 12.8 ka shell date appears too young in relation to the 13,100 +/- 180 date (GSC-4095; Blake, 1988) on shells in the immediate overlying gravel. The greater age of the stratigraphically higher shells may possibly be explained if they were reworked from the older underlying muds upslope by falling sea level, but this scenario is considered unlikely as most are intact. Despite the imperfect sequence, the three dates are considered to be in reasonable agreement, and an average age of about 13 ka BP is imputed to the series. This dated section (Grant, 1987, 1991) is in the marginal zone of the Robinsons Head Readvance and relates to an associated deglacial relative sea level of about 21 m."
