A scientifically based explanation for the areal/temporal distribution of the existing deposits is therefore needed.
The first and last units have the least areal extent.
We take an areal+typological approach to evaluate hypotheses relating to the origin of the construction.
Initial areal cell densities of 104 to 105 cells per slide were used.
Finally, we were careful to take into account lateral displacement and areal magnification.
It is the migration through a seaway which allows previously restricted marine communities to extend their areal distribution and colonize new environments.
This categorisation resulted in a significant areal effect.
Such a stipulation empowers regional governments to establish areal norms for different activities, taking into account local conditions.
