Source rocks in Qom formation entered hydrocarbon generation stage for the basin quickly subsidence in late Cenozoic ( about 4-5Ma), meanwhile source rocks in Jurassic have entered highly matured stage, generated lots of gas.

Qom组在新生代中晚期（约4Ma-5Ma）盆地快速沉降阶段进入生油阶段，而此时侏罗系已达到过成熟阶段，大量生成干气。

Superposition between the basin basement flexure under load and eustatic change of sea level or subsidence due to compaction with different way should produce various types of tectono-depositional episode. There are also some backland basins and relict back-are basins associated with foreland basins during the Late Triassic.
