**5. Chemical and mineralogical characteristic of diverse magma in diverse tectonic environment**

The Petrographic Classification of magma erupting in diverse tectonic regimes (**Figure 10**)—(1) Distention environment of thin oceanic crust (≈10 km) with the formation of basaltic magmas (e.g., Island and Atlantic rift). (2) Tectonic regime of hot-spot into an internal oceanic plate with the production of basaltic magma (e.g., Hawaii Island and Emperor submerged chain). (3–4) Compressive environment (subduction regime) with insular and continental arcs with the production of rocks with an evolved composition (felsic, andesitic, and rhyodacitic) (e.g., Japan, New Zealand, Chile, and Alaska). (5) Volcanic activity within a continental plate as a hot-spot with the formation of less-evolved and evolved composition, such as basaltic, andesitic, and rhyodacitic (e.g., Etna volcano). (6) Distention environment within a continental crust with the formation of basaltic, andesitic, and rhyodacitic (e.g., Africa rift valley).
