be due to alluvial deposits. The underlying probable weathered zone increases
from almost non-existent on IPMR 13 to reach the thickness of
20 m for a maximum depth of 30 m on IPMR10 (Fig. 8). This deepening
of the weathered zone may be related to the fracture zone in the vicinity of
IPMR10. A relatively long signal decay time reveals a small amount of clay
in the weathered zone. Higher water content and a longer decay time suggest
that more water is stored in this area than in KB Tanda area.
