  1. 1. Studying magmatic systems through chemical analyses on clinopyroxene - a look into the history of the Teno ankaramites, Tenerife

    University essay from Lunds universitet/Geologiska institutionen

    Author : Vendela Haag; [2020]
    Keywords : clinopyroxene; sector zoning; concentric zoning; mass wasting; magma recharge; Earth and Environmental Sciences;

    Abstract : Clinopyroxenes have the ability to crystallize over and respond to a large range of temperatures, pressures and chemical compositions, and thus, they are ideal for studies regarding the history of magmatic systems. In this thesis, the chemistry and zoning of four clinopyroxene crystals from an ankaramite sample from the Teno massif, Tenerife, were analysed. READ MORE
