As it has long been in relatively stable tectonic setting, it provides the favourable geologic conditions for oil-gas generation, accumulation and preservation.
由于盆地长期处于相对稳定的大地构造环境，这就为油气的生成、聚集、保存提供了有利的地质条件。

The process of generation and differentiation of granitoid magmas is con trolled not only by physical-chemical condition, but also is related to regional tectonic event.
花岗质岩浆的生成、分异过程不仅与物理-化学条件有关，而且受控于区域构造。

The source is abundant in this area, tectonic movement and petroleum hydrocarbon generation have good match.
