Using the lever rule the ratio of anorthite to diopside crystallizing at the eutectic is given by:-dg/dh = 42/58 Left of the eutectic we get a similar situation Diopside (g) crystallizes first, then at point d it is joined by anorthite (h).

Anorthite is the calcium-rich endmember of the plagioclase solid solution series, the other endmember being albite, NaAlSi 3 O 8.Anorthite also refers to plagioclase compositions with more than 90 molecular percent of the anorthite endmember. percent of the anorthite endmember.

As cooling continues further, the liquid will move down the liquidus toward These include olivine, pyroxene, amphibole, biotite, and plagioclase feldspars. Crystallization behaviour is illustrated best by using the NaAlSi3O8 (albite or Ab)–CaAl2Si2O8 (anorthite or An) plagioclase system shown in Figure 4.

In the system CaO-MgO-Al 2 O 3-SiO 2, the tetrahedron CaMgSi 2 O 6 (di)-Mg 2 SiO 4 (fo)-SiO 2-CaAl 2 SiO 6 (CaTs) forms a simplified basalt tetrahedron, and within this tetrahedron, the plane di-fo-CaAl 2 Si 2 O 8 (an) separates ...

Pure diopside g joins liquid d and anorthite h d is called the eutectic point: MUST reach it in all cases

is on the left and XPL on the right. From top to bottom: dunites, pyroxenites (note the exsolution lamellas From top to bottom: dunites, pyroxenites (note the exsolution lamellas in the orthopyroxene, and the intersticial plagioclase) , olivine-norite.

Liquidus temperatures in the alkali aluminosilicate systems are much more sensitive to composition than those in the equivalent Ca-aluminosilicate systems. The effect is evident when Al 2 O 3 is added at constant M x /Si ratio, as illustrated in Fig. 8.2 for the pseudobinary joins M x O·2SiO 2 -M x O·2SiO 2 ·Al 2 O 3.

Sodium oxide also has a strong effect at decreasing the liquidus temperature in the silica rich side of the Na 2 O–SiO 2 binary system. In the silica primary phases (cristobalite and tridymite), the addition of about 25% soda to pure silica will reduce the liquidus temperature from 1713 to 793 °C [ 3 ].
