Figure B3-2.2 View towards Fort Canning Hill from the Central Business District, and a few locations
where FCBB have been encountered (according to Shirlaw et al., 2003).
Pencil for scale
Hard clay and rock fragments
with faint fabric roughly
parallel to stained
discontinuity
Stained sandstone along
discontinuity (possibly orthogonal
to bedding). Evidently open to
elements for longer time than
discontinuity below.
Hard red clay and rock fragment infill-
probably due to opening rather than
transport of the whole mass as in a
landslide
Strong, medium grained
sandstone (probably
Jurong). Note lack of
weathering along angular
discontinuity (possibly
bedding-parallel).

not a weathered product of the sandstone and, anyway, the contained boulders in the FCBB
generally show little weathering. The red clay sometimes appears as an in

joint structure in sandstone blocks
