Revised but simplified geological map of Singapore derived from our interpretation of all available BCA data, including offshore bathymetrical data that provides some measure of constraint on fault patterns offshore.
The map shows the principal geological units with the major fold, thrust, and fault structures superimposed.
The Mesozoic Jurong and Sentosa group outcrops are shown undivided for clarity (cf. Figure 3).
‘Murai Reservoir’ is highlighted as a key exposure of the Murai Thrust in western Singapore; NTU – Nanyang Technological University campus (see text). Named brittle faults are labelled: HRF - Henderson Road Fault; PRF - Pepys Road Fault; NSF - Nee Soon Fault; SF – Seletar Fault; BTFZ - Bukit Timah Fault Zone. Boxed area is shown in more detail in Figure 5. The inset strain ellipse shows the array of fault orientations in Singapore in relation to a predicted maximum compressive stress direction, σ1 (redrawn after McClay, 2013).
