The recent deposits of the Comowine phase are found to the north, those of the Moleson phase in
the middle and the ones of the Wanica phase in the south of the study area. The seismic lines are
projected in the Comowine and Moleson phase.

The Coastal Plain of Suriname is formed on sediments that have been deposited since the Late
Cretaceous. The sediments are known as the Corantijn Group.
Drinking water is withdrawn from three major aquifers within this Corantijn Group: the AA-Sand
A
aquifer, the Coesewijne aquifer and the Zanderij aquifer, found in the formations of th the th same
respective names (note: the A-Sand Sand Formation in which the aquifer is found has been renamed
Burnside Formation; Wong, 1989).
