Boninite is an unusual, plagioclase-free magnesian andesite, occurring as vesicular pillow lavas and hyaloclastites, accompanied by andesites and dacites in Chichi-jima, Bonin Islands. The Bonin Islands belong to the Izu-Mariana arc and consist of dominant volcanic rocks and subordinate sedimentary rocks of late Oligocene-early Miocene age. The chemistry of boninite is characterized by high contents of MgO. Cr and Ni similar to primitive basalts, but apparently in ill accord with its relatively… 

Ferropigeonite quartz dacites from Chichi-jima, Bonin Islands: Latest differentiates from boninite-forming magma

Chichi-jima, Bonin Islands, consists of dominant Eocene submarine volcanic rocks, comprising boninites, andesites and dacites, and subordinate sedimentary rocks. The dacites occur frequently in

Petrology and geochemistry of boninite series volcanic rocks from the Mariana trench

Boninite series volcanic rocks have been recovered from three dredge hauls on the inner slope of the Mariana Trench. These hauls included olivine boninites, boninites, boninitic andesites and

Petrology and Geochemistry of Boninite-Series Volcanic Rocks, Chichi-Jima, Bonin Islands, Japan

An Eocene submarine boninite-series volcanic center is exposed on the island of Chichi-jima, Bonin Islands, Japan. Five rock types—boninite, bronzite andesite, dacite, quartz dacite, and

CHROME-SPINELS IN A BASANITIC LAVA FROM NANZAKI VOLCANO, IZU PENINSULA

Spinels (sensu lato) in the Nanzaki basanitoid show a continuous compositional variation from chromian spinel (sense stricto) enclosed in the magnesian olivine and augite phenocrysts to titaniferous

28. MINERAL CHEMISTRY OF FOREARC VOLCANIC ROCKS FROM THE IZU-BONIN ARC, HOLES 792E AND 793B1

The Izu-Bonin forearc basement volcanic rocks recovered from Holes 792E and 793B show the same phenocrysts assemblage (i.e., Plagioclase, two pyroxenes, and Fe-Ti oxides ±olivine), but they differ in

ORIGIN OF CRETACEOUS HIGH MAGNESIAN ANDESITES FROM SOUTHEAST KALIMANTAN

High magnesian andesites are found in the Cretaceous Haruyan volcanics in Southeast Kalimantan. The rocks have Mg# 67 – 69, but low concentrations of Ni (44 – 60 ppm), Cr (37 – 411 ppm) and, except

The Izu-Bonin forearc basement volcanic rocks recovered from Holes 792E and 793B show the same phenocrysts assemblage (i.e., Plagioclase, two pyroxenes, and Fe-Ti oxides ±olivine), but they differ in

Petrology and Geochemistry of Boninites from the North Termination of the Tonga Trench: Constraints on the Generation Conditions of Primary High-Ca Boninite Magmas

We report here a detailed mineralogical, geochemical, and experimental study of a high-Ca boninite suite from the northern termination of the Tonga trench. Most samples are strongly olivine

The boninite revisited

Boninite occurring in Chichi-jima, Bonin Islands, is a rare rock, no exact equivalent known anywhere, and is a vesicular, feldspar-free glassy andesite according to SiO2 content (56-59%), consisting

Chemical analyses of over seventy lavas or dykes containing spinel lherzolite inclusions of high pressure mineralogy, show that most host magmas are of alkali olivine basalt or basanite composition

Minor-Element Distribution in Olivine

Microprobe analyses of natural igneous olivines from many rocks confirm that Ni increases and Mn de-decreases with increasing Mg content. A strong crystal-chemical control is apparently not
