Vienna: Wilhelm Brauchmüller. p. 72. <q>v. Richthofen's Namen gleichfalls ganz fallen zu lassen, dafür liegt wol nicht derselbe Grund vor. Dass die Oligoklasgruppe der "Quarztrachyte", dies muss der Name für die ganze Reihe bleiben, von der Orthoklasgruppe oder den "Rhyoliten" getrennt werden müsse, dafür plaidirte Roth gleichfalls schon in seiner Arbeit. Unser 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).</q></cite><span title="ctx_ver=Z39.88-2004&rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Abook&rft.genre=book&rft.btitle=Geologie+Siebenb%C3%BCrgens&rft.place=Vienna&rft.pages=72&rft.pub=Wilhelm+Brauchm%C3%BCller&rft.date=1863&rft.aulast=Ritter+von+Hauer&rft.aufirst=Franz&rft.au=Stache%2C+Guido&rft_id=https%3A%2F%2Farchive.org%2Fdetails%2Fbub_gb_CYwAAAAAcAAJ&rfr_id=info%3Asid%2Fen.wikipedia.org%3ADacite" class="Z3988"></span></span> </li> <li id="cite_note-3"><span class="mw-cite-backlink"><b><a href="#cite_ref-3">^</a></b></span> <span class="reference-text"><link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1238218222"><cite id="CITEREFTrollDonaldsonEmeleus2004" class="citation journal cs1">Troll, Valentin R.; Donaldson, Colin H.; Emeleus, C.
