A new lithostratigraphical framework for Singapore is proposed, based on the analysis of c.
20,000 m of core recovered from 121 c. 205 m deep boreholes and augmented with 218
field localities from across Singapore. The new framework describes a succession dating

were used to constrain the ages of key sedimentary units. The oldest known sedimentary
rocks in Singapore are found to be the deformed Carboniferous (Mississippian) Sajahat …
