B. they come from a variety of source rocks. C. the magmas' heat can melt varied rock from the walls of the magma chamber. D. the …Fractional Crystallization Also Makes Magma Richer In Silica. A magma chamber is a space within the Earth that's filled with molten rock. If the magma in a magma chamber has a low viscosity—meaning it flows easily

Earth has a layered structure that consists of the inner core
extinct or post-subduction zone settings (Fig. 1).If subduction zone magmas have high metal contents ...There are three major types of magma. Basaltic (or mafic) magma predominates in nonexplosive volcanic eruptions. It is a high-temperature magma (1 located on the volcanic front of the Izu arc (Figure 1) but not nearly so much as the …Large to giant porphyry Cu deposits are typically associated with magmas from either active

According to Bowen's Reaction Series ( …The cooling behaviour of intermediate magmas lie somewhere between those of mafic and felsic magmas. Typical mafic rocks are gabbro (intrusive) and basalt (extrusive). Typical intermediate rocks are diorite and …The precursor basaltic magmas with high Nb/Ta values may be derived from a subarc mantle modified by silicic melts or solute-rich supercritical fluids with high Nb/Ta …Viscosity of Magmas.

Although there are many exceptions to this trend mafic magmas typically have 1% to 3% volatiles What happens as the relative amount of silica in a magma or lava increases? Viscosity increases Viscosity decreases Volcanic eruptions become more explosive Volcanic eruptions become less …Usually magmas rise in stages
