Cassini considers that the geological setting may have some affinity with intracontinental 'hot-spot' epithermal gold mineralisation, rather than the more common island arc
setting found elsewhere along the Pacific Rim.
The Kermadec Islands are a subtropical island arc
in the South Pacific Ocean.
The Chilas Complex is a ~40 wide and 300 long composite plutonic body exposed in the central part of Kohistan island arc
, which formed first as intra-oceanic island arc
in the Neo-tethyan oceanic crust and later transformed into Andean-type continental margin after the closure of back-arc basin.
Many also take place hidden from view on the sea floor, with some of the most active underwater volcanoes located in the Tonga-Kermadec island arc
in the south-west Pacific.
Large-scale island arc
volcanic activities happened in intermediate and late Jurassic epoch, which belongs to a set of rock association dominated by andesite.
The largest and southernmost of the Mariana Island Arc
, Guam is located east of the Philippines.

But the existence of this enormous island arc
, which they believed to have stretched between Baltica and Siberia, does not agree perfectly with the data from regional geology.

As a result of this subduction, there exists both intermediate focus earthquakes within the subducted plates and a chain of active volcanoes along the island arc
. Although the Lesser Antilles is considered one of the most seismically active regions in the Caribbean, few of these events have been greater than M7.0 over the past century.
