Nachweis der Altersverschiedenheit spricht nur um so dringender dafür. Für den Geologen genügen vielleicht die Namen "jüngerer" und "älterer" Quarztrachyt. Soll jedoch entsprechend der Sonderbezeichnung für die jüngere Gruppe, auch für die ältere Gruppe der Quarztrachyte ein besonderer Name eingeführt werden, so möchte der Name "Dacit" vielleicht entsprechend sein, da die Gruppe im alten Dacien eine besonders hervorragende Rolle zu spielen scheint).

Once at the cold surface, the sodium rich magma crystallizes plagioclase, quartz and hornblende. Accessory minerals like pyroxenes provide
