the modulus of deformation of granular soils varies with the magni tude of confining or lateral pressure. the first observation is illustrated by figure which ;shows a typical stress-strain curve for a crushed limestone specimen tested triaxially. Ex cept for a small curved section at the beginning, there is a sizeable portion
the thickness of the gumai formation varies and is as much as 2,700 thick in basins. the formation thins at basin margins and across highs the gumai formation is the regional seal for the batu raja limestone in south sumatra but also contains some reservoir intervals.
indonesia harbors some of the oldest known surviving cave art. previously, the earliest dated rock art from this region was a figurative painting of a sulawesi warty pig this image from leang bulu sipong in the limestone karsts of maros-pangkep, south sulawesi, was created at least 43,900 years ago based on uranium-series dating.
