The Jurong Formation forms the west and southwest of the Singapore Island. The formation consists of sedimentary rocks of late Triassic to early Jurassic age. The rocks include various types of mudstone, sandstone, shale, conglomerate, phyllite, slate and limestone. They have been intensely folded with their structural strike generally oriented NW-SE and faulted with the faults generally aligned parallel with or perpendicular to the fold strike. The Jurong Formation has been studied for the potential development of rock caverns. Extensive investigations including geological mapping, seismic reflection surveys, and deep coring have been conducted. This paper presents some of the results from the investigations and discusses the potential of cavern development in the Jurong Formation.
