  • PyroxeniteMineral and Healing Properties

    The pyroxene-rich rocks which result from the contact metamorphism of impure limestones are described as pyroxene hornfelses (calc-silicate hornfelses). The igneous pyroxenites are closely allied to the gabbros and norites from which they differ by the absence of feldspar and to the peridotites which are distinguished from them by containing
