4.3.1.3 Engineering geology<br />

According to drilling data of Male Island for the last 20 years, the stratums of the Male Island<br />

could be divided to following soil elements: artificial fill (Q ml 4 ), loosing-state fine ~ medium<br />

sand (Q m al<br />

4 ), coral fragment mixed medium-dense sand (Q 4 ), coralline algae limestone which is<br />

underlying below 10~13 m. The Pleistocene coralline algae limestone deposits to several meters<br />

in drilling pore which is less 40 m depth, the brown part of Figure 5.16 shows data for boreholes<br />

where Pleistocene coralline algae limestone and the yellow part shows Holocene coralline rocks<br />

were reached.<br />
