  1. Pyroxenite is an ultramafic igneous rock consisting essentially of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite. They are classified  into clinopyroxenites, orthopyroxenites, and the websterites which contain both pyroxenes. Basically dark rocks high in magnesium and iron

     

    Micaceous pyroxenite found near syenite but I don't know much else.
