Why do magmas rise from the mantle and lower crust? What is the difference between a royalties and a basalt? A rock with a porphyritic: What are phenocrysts? A mafic magma: A silicic magma: As a mafic magma cools what are the first minerals to crystallize? The higher temperature minerals in the bowen's reaction series are enriched in and than the lower temperature minerals lower in What Wh minerals comprise the discontinuous portion of the Bowen's reaction series? at minerals comprise the continuous portion of the Bowen's reaction series? What As plagioclase crystallizes, it is more enriched in As olivine crystallizes, it is more enriched in Zoning in crystals results from: Crystal fractionation of plagioclase pushes the melt to higher --. Quartz is unstable in the presence of: The polymorphs of quartz that form at very high pressures are The polymorphs of quartz that form at high temperature and low pressure are The most abundant minerals in the Earth's crust are The solid solution series for feldspars that involve Ca Na and Al Si coupled substitutions is: The solid solution series for feldspars that involves Na and K substitution is: The solvus shows: minerals comprise the residual phases of the Bowen's reaction series? than the melt. than the melt The liquidus shows:Explanation / Answer
2) rheolites are the fine grained igneous rocks rich in silica. Where as basalt is extrusive igneous rock formed due to cooling of magma.rheolite is a coarse grained rock and basalt is a fine grained rock.
3)granite has a porphyritic texture.
4)mafic magma means the magma coming out is enriched with magnesium and ferrum or iron and also enriched with sodium and calcium.
5) magma or igneous rocks rich in silica.
6)usually mafic magma melts at high temperature so olivine and pyroxene rich in Mg and Fe and poor in Silica are the minerals that crystallize first and the rocks formed are mafic rocks.
7)higher temperature are rich in olivine and pyroxene containing Mg and Fe. Poor temperature has Silica.
8) mafic minerals like olivine and pyroxene has the discontinue s process in Bowens reaction series.
9) plagioclase feldspars rich in calcium and sodium are the continuous portion in Bowens reaction.
10) calcium is rich when plagioclase crystallize.
11) Magnesium is rich when olivine crystallize.
12)minerals which does not maintain chemical equilibrium with the magma.
