The type of magma associated with oceanic hot spots - mafic Decompression melting in this setting forms a long, submarine ridge - divergent boundary When mafic magma rising from the mantel rises through this type of crust, it will form int-felsic magma - Continental crust Shield volcanoes may form here, when magma upwells from the asthenosphere - hot spot The type of magma that most commonly forms at subduction zones - int-felsic magma This tectonic setting can form an explosive caldera - ...
