Brief
Description
Sundaland
is a complex and unusual continental region assembled during
the Triassic. Today it includes extensive shallow seas surrounded
by subduction and collision zones, and during the Pleistocene
it was emergent. It is often assumed to be a region of long-term
stability. However, important Cenozoic deformation is recorded
in the numerous deep sedimentary basins alongside young
elevated highlands. The region has exceptionally high rates
of sediment production despite a relatively small land area
and low elevation. In size, heat flow, crust and mantle
character the region resembles the Basin and Range province
or the East African Rift, but is quite unlike them in tectonic
setting. We invite contributions addressing the timing,
nature and causes of crustal subsidence and elevation, the
character and source of sediment filling the basins, and
the nature of the crust and mantle beneath the region, which
will contribute to understanding the Cenozoic history of
this region. |
