Nickel in high-alumina basalts - pubs.er.usgs.gov

The typical volcanic rocks of most island arcs and eugeosynclines, and of some continental environments, are basalt, andesite, and dacite, of high alumina content. The high-alumina basalt differs from tholeiitic basalt primarily in having a greater content of the components of calcic plagioclase

Basalt - Wikipedia

For a basalt magma simultaneously crystallizing plagioclase, clinopyroxene, and olivine, a possible result is the selective removal of mafic minerals and the preferential retention of plagioclase crystals along the intrusion margin. This represents a possible mechanism for generating plagioclase-phyric magmas of high-alumina basalt composition. In this study, a combined basalt crystallization ...

Origin of high-alumina basalt, andesite, and dacite magmas

High-alumina basalt occurs at eight localities in the Taupo Volcanic Zone associated with the Okataina, Maroa and Taupo calderas. At Tarawera the basalt is associated with a series of craters aligned NNE, and at K Trig. a series of scoria cones of similar alignment.

High‐alumina basalts (HABs) that occur throughout the central part of the Taupo Volcanic Zone (TVZ) are associated particularly with faulting, and many occur where faults intersect caldera margins. For convenience, the basalts are described in terms of three geographic‐tectonic segments

At intermediate dephs high-alumina basalt magmas are formed (Mount Fuji, Southern Yatsugatake Volcanic Group, Mount Ontake, for instance) and at dephs greater than 250 km alkali olivine basalt ones (Oki-Dōgo, for instance). Hisashi Kuno contributed to unfold this causal correlation.

Basalt ~ Learning Geology

The term Alumina is usually applied to cermamics based predominantly on aluminium oxide and products containing more than 85% are often referred to as high density alumina. Alumina ceramic has been developed and optimized for maximum wear resistance and corrosion resistance.

High-alumina basalt may be silica-undersaturated or -oversaturated (see normative mineralogy). It has greater than 17% alumina (Al2O3) and is intermediate in composition between tholeiite and alkali basalt; the relatively alumina-rich composition is based on rocks without phenocrysts of plagioclase.
