Formasi Ignimbrite lan Nepheline Syenite


Formasi Nepheline Syenite lan Ignimbrite


Tatanan

tatanan
ignimbrites sing kawangun saka dicampur banget lingkungan diurutake saka awu vulkanik utawa tuff lan pumice lapilli, umum karo pecahan lithic kasebar.   
syenites nepheline sing kawangun amarga aktivitas igneous alkalin lan umumé kawangun ing wilayah dharatan crustal nglukis utawa ing zona subduksi cordilleran.
