The above shows that granulite facies metamorphism occurred in the crust of (increasing) thickness and caused by strong tectonic disturbance and regional high heat flow.

The deep crust-mantle structure of the basin controlled the heat flow, the types of sags, the abundance of petroleum, and the distribution and accumulation of oil and gas.

The volcanic activities have relations to the heat-flow upwelling, crust thinning, upper mantle and lower crust melting, and upward movement of the melt materials along the block boundaries.
