12.7.5 Summary (Collision-Related Basins)
This group of basins comprises intramontane
basins, Pannonian-type basins, and basins caused by lateral extrusion of continental blocks.
(Foreland basins are discussed in Sect. 12.6).
These complex basin types are interrelated and
also show affinities to rift basins, retroarc and
pull-apart basins.
Intramontane basins are commonly elongate,
narrow, and evolve during late orogenesis. They
primarily result from extension, but they often
show a strong strike-slip component, syn-depositional basin segmentation, and a late compressional phase.
These basins collect predominandy clastic and
lacustrine sediments derived from nearby sources reflecting the local clirnate. Many basins are
629
affected by vo1canism. The total sediment infillings can reach great thicknesses.
- Basins resulting from gravitational orogenie
collapse and lateral extrusion are normally dorninated by trans tension. In many aspeets, including their basin fill, they resemble intramontane basins.
Pannonian-type basins on thinned eontinental
erust are more complex both in their structural
and sedimentary evolution. Their subbasins
may display diaehronous subsidenee and different eoeval depositional environments of
their sediment fills (including relatively deepmarine eonditions). Their late-stage evolution
tends to be more uniform and eharacterized by
lacustrine and fluvial deposition.
