• Erebus is the world's only presently erupting phonolite volcano.
• Phonolite occurs in the related Pilanesberg Complex and Pienaars River Complex.
• This mountain is a volcanic cone consisting of trachyte and phonolite.
• It is filled with small volume tephritic phonolite and phonolite lava flows.
• It is filled with small volume tephritic phonolite and phonolite lava flows.
• Later activity produced trachyte and phonolite plugs and lava flows.
• It is made of a type of rock called phonolite.
• Rock types are made up of phonolite and ignimbrite.
• These include nephelinite, basanite and peralkaline phonolite, trachyte and comendite lavas.
• Created in 2009, it is made of a number of phonolite stones.
• Phonolite is the fine-grained extrusive equivalent.
• Units within the complex include carbonatite, nepheline syenite, phonolite, and ijolite.
• A few geological processes and tectonic events can melt the necessary precursor rocks to form phonolite.
• Phonolite covers most of its surface.
• The majority of the basalt and phonolite cones sit directly on the sandstones of the Middle Bunter.
• During the Tertiary volcanic magma streams broke through the sandstone layer and solidified into basalt and phonolite.
• Faujasite occurs in vesicles within basalt and phonolite lava and tuff as an alteration or authigenic mineral.
• Mont Gerbier de Jonc was formed 8 million years ago when a volcano erupted molten phonolite lava.
• The Heldburger Castle Hill is also made of basaltic rock that phonolite ( Sparkling Stone ) is called.
• The dikes or sills consist either of phonolite, tinguaite, lamprophyre micromalignite, lamprophyre micromelteigite, or carbonatite.
