If magmas are related to each other by some processes, that process would have to be one that causes magma composition to change. Any process that causes magma composition to change is called magmatic differentiation.Over the years, various process have been suggested to explain the variation of magma compositions observed within small regions.
The means that the overall composition of the magma near the top of the magma chamber will become more felsic, as it is losing some iron- and magnesium-rich components. This process is known as fractional crystallization. The crystals that settle might either form an olivine-rich layer near the bottom of the magma chamber, or they might remelt ...
This process is called fractional crystallization. Also, basaltic magmas have enough excess heat to partially melt the continental host rocks through which they are ascending. Because continental rocks are generally higher in silica, potassium, and sodium than are oceanic rocks, this process of assimilation and mixing can also play. Read More
Fractional crystallization and accumulation of crystals formed during the differentiation process of a magmatic event are known as cumulate rocks, and those parts are the first which crystallize out of the magma.Identifying whether a rock is a cumulate or not is crucial for understanding if it can be modelled back to a primary melt or a primitive melt, and identifying whether the magma has ...
The data is presented in the form of a "precompiled" spreadsheet which contains selected analyses culled from the GEOROC database and a USGS Open File report. Students make graphs from the data to learn about the petrologic processes related to the eruption and in situ crystallization of basaltic magma.

Oct. 22 (UPI) -- Most volcanic eruptions are of the basaltic variety. The eruptions are typically rather tame. Every once in a while, however, the same types of eruptions turn violent and explosive. New research suggests rapid magma crystallization is responsible for the dark side of basaltic eruptions. Hazardous basaltic eruptions are known as Plinian eruptions, named for Pliny the Elder, the ...

A new paper, "Magma fragmentation in highly explosive basaltic eruptions induced by rapid crystallization", published in the journal Nature Geoscience, proposes an explanation for this discrepancy. When magma is rapidly expelled from a volcano, it undergoes rapid cooling.
9 days ago· Previously, scientists argued the process of magma crystallization was too slow to account for explosive basaltic eruptions, but the latest research — published this week in the journal Nature Geoscience — showed that under right temperatures and chemical conditions, the process can occur surprisingly fast.
This glass is the residual material left after crystallization of pyroxene and feldspar, analogous to rhyolitic melt which may be generated from fractional crystallization of a basaltic magma.
In discussing the crystallization of a granitic magma it is sometimes assumed that there is a simple pro rata increase of the water content of the residual liquid as crystallization proceeds; i.e., it is assumed that, when the proportion of crystals amounts to one-half, the amount of water in the liquid is doubled, and when the crystals are nine-tenths, the water is increased tenfold.
Sep 23, 2019· The minerals that make up igneous rocks crystallize at a range of different temperatures.
Basalt magma carries the heat necessary for melting into the lower and middle crust, but partial melting and magmatic differentation combine to favor production of magmas more felsic than basalt. In the ocean basins, basaltic magma only encounters a thin mafic crust on its way to the surface.
1) Demonstrated that as a basaltic magma cools, minerals tend to crystallize in a systematic fashion, based on their melting temperatures 2) During the crystallization process, the composition of the remaining liquid portion of the magma also continually change
Crystallization of basaltic magma as recorded by variation of crystal-size in dikes. By HELMUT G. F. WINKLER, D.Phil. Department of Mineralogy and Petrography, University of GSttingen. [Taken as read November 25, 1948.] I T is a familiar fact that in dikes, lava-flows, and sills the grain-size
Crystallization of Magma and Lava produced from the melting of mantle usually produced basaltic magmas, compositions that are referred to as mafic because of their high proportions of Mg and Fe.Mantle rocks themselves are called ultramafic.

5 days ago· A new paper from scientists at The University of Manchester has discovered why some volcanic eruptions are more explosive than others. Basaltic eruptions are the most common form of volcanic eruption, and for the most part, they involve relatively tame magma .
In this exercise, students use geochemical data from volcanic glasses and minerals in lavas and drill cores from the solidified Kilauea Iki lava lake to learn about the petrologic processes related to the eruption and in situ crystallization-differentiation of basaltic magma.

What describes how an entire suite of silicate minerals can form from a single basaltic magma as it cools and crystallizes? ... Mineral crystals that form early in the crystallization process will have better-developed crystal faces ...
High-temperature fractional crystallization of relatively water-poor granite magmas may produce single-alkali-feldspar granite, and lower-temperature crystallization of relatively water-rich magma may produce two-feldspar granite. During the process of fractional crystallization, melts become enriched in incompatible elements.
