Petrology and petrogenesis of the Mount ... SpringerLink

This batholith may represent the plutonic counterpart of the highalumina basalt association. A petrogenetic model is developed in which this intrusive series evolved from one batch of magnesian highalumina basalt, represented by the oldest intrusive phase, by successive crystal fractionation of ascending residual magma.

Synthetic model for the emplacement of the Egersund^Ogna massiftype anorthosite. (a) Ponding at the base of the crust of the paren tal highalumina basalt, which started crystallizing at c. 1011 kbar. (b) Ascent of the magma to a second chamber at kbar, where it crystallized most of the HAOM (5^7 wt % Al2O3) and labradorite plagioclase.

The origin of island arc highalumina basalts | SpringerLink

Abstract. A detailed examination of the hypothesis that highalumina basalts (HAB) in island arcs are primary magmas derived by 50–60% partial melting of subducted ocean crust eclogite shows that this model is unlikely to be viable. Evidence suggests that the overwhelming majority of arc HAB are porphyritic lavas,...

On highalumina mare basalts

A group of crystalline clasts in breccia 14063 are also aluminous mare basalts with higher TiO2, Na2O, Mg/Fe ratio and lower FeO than other aluminous mare basalts. Composition of ilmenite clinopyroxene, and plagioclase confirm that crystallization took place from a melt with high TiO2 and Mg/Fe.

Basalt New World Encyclopedia

High alumina basalt may be silicaundersaturated or oversaturated. It has greater than 17% alumina (Al 2 O 3 ) and is intermediate in composition between tholeiite and alkaline basalt; the relatively aluminarich composition is based on rocks without phenocrysts of plagioclase.

Basalt (pronounced / b ə ˈ s ɔː l t /, / ˈ b æ s ɒ l t / or / ˈ b æ s ɔː l t / ) is a common extrusive igneous (volcanic) rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of a planet or moon. Flood basalt describes the formation in a series of lava basalt...

Nickel in highalumina basalts

Abstract New analyses of highalumina basalts reveal an average nickel content higher than previously indicated. Ni in highalumina basalts correlates with magnesium in the same way as it does in other basalt types. There is therefore no reason, based on Ni contents, to hypothesize a special origin...

Igneous Rocks Plate Tectonics

Thus, these calcalkaline basalts are often referred to as high alumina basalts. Recall that the Feenrichment trend exhibited by the tholeiitic and alkaline rock series can be explained by crystal fractionation involving removal of early crystallizing Mgrich olivines and pyroxenes from the parental basaltic magmas.

Nickel in highalumina basalts ScienceDirect

Ni in highalumina basalts correlates with magnesium in the same way aa it does in other basalt types. There is therefore no reason, based on Ni contents, to hypothe size a special origin for highalumina basalts and it is permissible (based on Ni contents) to form andites by fractional crystallization from highalumina basalts.
