It usually occurs together in the same igneous complex with peridotite. Pyroxenite mostly forms by accumulation of pyroxene crystals in the mafic-ultramafic igneous intrusions. It forms variously shaped igneous bodies like sills, layers, dikes, etc.<\/p><p>Pyroxenite is a common rock in the lower part of the oceanic crust, where it is associated with depleted peridotite. \u201cDepleted\u201d means that peridotite has gone through partial melting to yield\u00a0basaltic melt, which forms the upper part of the oceanic crust (sheeted dikes and pillow lavas). Depleted peridotite is rich in orthopyroxene and associated pyroxenites are usually either or olivine ortho pyroxenites. Pyroxenite may occur as xenoliths\u00a0in volcanic rocks.<\/p><p>Metamorphic rocks with a pyroxenite composition should be named differently. These rocks are usually high-grade granulites. The rock name pyroxenite should be reserved to true igneous rocks to avoid unwanted confusion and ambiguity.<\/p><p>Pyroxenite and peridotite may host economically important metals like chromium, nickel, platinum, iridium, osmium, etc. Serpentine and\u00a0talc\u00a0are mined from metamorphosed ultramafic rocks.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-89fddbc elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"89fddbc\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-9e2bf9c\" data-id=\"9e2bf9c\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-7763b4c elementor-widget elementor-widget-text-editor\" data-id=\"7763b4c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Pyroxenite is\u00a0<b>an ultramafic igneous rock consisting essentially of minerals of the pyroxene group, such as augite, diopside, hypersthene, bronzite or enstatite<\/b>.
