The Slab Component and Island Arc Igneous Rocks

Explain how to create slab components on igneous rocks of arc arcs. Let's consider the environmental arcs of the front and rear arc basins that form the subduction of the oceanic plate under the oceanic plate. Volcanic activity is concentrated in the volcanic arc and is usually almost above the leading edge of the subduction plate. Grooves are often formed where the plate encounters and begins to jump. Fisch, Meschede and Blakey), a basin where the pre-sink basin is closest to the subduction / trench and then the main arc and the far arc side is close to the receding arc is formed in a series of basins (Mitchell and Reading, 1971; Frisch, Meschede and Blakey) ). .

Igneous rocks are rocks that crystallize from lava and magma. Melt consists of various components of existing rock melting in the subduction zone or inside the mantle. Because the molten metal is very hot, it will rise through the colder country rocks. As it moves, it cools and forms various types of rocks through a process called fractional crystallization. Igneous rocks can be seen on the mid-ocean ridges, arc volcanic areas or plate hot spots

The uniqueness of these islands is in stark contrast to our understanding of global plate tectonics and volcanoes formed around the Pacific Rim volcanic zone. Kilauea and Hawaiian volcanic zones are moved by geological hotspots in the central Pacific.

Island arcs are groups of islands or islands formed from volcanic activity along the subduction zone. Subduction occurs when marine lithosphere sinks to continental or oceanic lithosphere. Submerged rocks melt into magma in the asthenosphere and some rock surfaces surfaced to form volcanoes. On the ocean floor, these volcanoes gradually form islands. The arc of each island is next to the deep groove. The arc of most islands is part of the circle of fire around the Pacific Ocean, but it is also found in the Aegean Sea and the Caribbean Sea.
