Conclusions
The continental masses of the craton are affected by different
structural disturbances due to extensional and collisional setups. It is
with reference to the occurrence of normal and thrust faults. The amount
of strike-slip components can vary. In the realm of the present study,
therefore, I have addressed the continental setups in a short and
descriptive way with the help of existing literatures. A simple
association of intracratonic sag basin, rift basin and passive margin
basin is proposed in an extensional set up and a trench, forearc,
back-arc and foreland basin is proposed for a collisional set up in
active margins. As Nature is not uniform, these models can just serve as
a generalized idea but hypotheses keep coming.
However, the role of tectonics never really ends here and plays an
important part in a marine setup where sea levels, sediment supply and
their rates differ causing events of transgression and regression and
sediment accumulation leading to different depositional tracts.
Accomodation discussed in sequence stratigraphy in sedimentary basins
refers to the vertical space available for sediments to fill in.
Tectonic activity, sea level & sediment supply are some important
parameters that will govern the events of transgression & regression,
in marine setups.
