A new slab is formed at the overriding plate owing to the regional compression and the density contrast of the continental block and oceanic plate . or doubly convergent wedge.

The Cenozoic plate tectonics of the Indonesian region have generated a complex assemblage of micro-continental blocks and marginal ocean basins surrounded by extensional margins, subduction zones and major transcurrent faults.

The original paleogeographic position of the continental blocks is debated, but some studies suggest a Gondwana affinity of many allochthonous terranes, whereas others infer a Siberian or Tarim origin for the same blocks.
15.
These islands have emerged from the abysses as a result of gigantic underwater volcanic eruptions that happened thousands of kilometres to the east of the continental block made up of Africa and Madagascar.
16.
The oceanic plate is subducting southwards underneath the continental block which is being buoyed by the rock which is subsequently being melted ( partial melting ) by the high temperatures and pressures associated with the process.

They concluded that this supported their original conjecture that the variations were due to an increasing " crustal " component in subducted sediments as the continental blocks in the north were approached ( China and Taiwan ).
18.
In his survey article, Storey concludes that " from the currently available evidence, plumes are not the ultimate driving force for continental breakup, " although they may be the main cause of splitting off smaller continental blocks.

The code that handles consists of songs and instrumental pieces with a focus harboring native rhythms and airs both Ecuador and Latin America rescuing own musical roots and common that make us a cultural continental block from the origins of our history as American peoples.

Britain during this period ( late Precambrian / early Cambrian ) lay about 70 degrees south of the equator at the margin of a large ocean ( to the north ) and with a large continental plate to the south, the ocean is accepting sediment from the continental block.
