An effect of flat slab subduction would have been a magmatic arc gap.
The chapters on mid-ocean ridges and subduction zones were disappointing.
For example the basalts could be inferred to have intraplate characteristics, and the andesites to be subduction-related.
Continuous subduction also leads to off-scraping of the metamorphic blocks under low-temperature conditions.
They are, however, characteristic features of subduction-related magmas or of continental tholeiites, including flood basalts.
Evolution of retreating subduction boundaries formed during continental collision.
Thus, fluids associated with subduction may have been responsible for triggering partial melting of lithosphere already experiencing decompression as a result of extension.
With continuing subduction the pelagic sediments might have been dragged beneath the accretionary prism leading to compaction and expulsion of large amounts of pore fluids.
