Phonolite - Wikipedia

Phonolite is an uncommon shallow intrusive or extrusive rock, of intermediate chemical composition between felsic and mafic, with texture ranging from aphanitic (fine-grained) to porphyritic (mixed fine- and coarse-grained). Phonolite is a variation of the igneous rock trachyte that contains nepheline or leucite … See more Unusually, phonolite forms from magma with a relatively low silica content, generated by low degrees of partial melting (less than 10%) of highly aluminous rocks of the lower crust such as tonalite, monzonite See more Phonolites can be of interest as dimension stone or as aggregate for gravels. Rarely, economically mineralised phonolite-nepheline syenite alkaline complexes can be associated with rare-earth mineralisation, uranium mineralisation and See more Phonolite is a fine-grained equivalent of nepheline syenite. They are products of partial melting, are silica-undersaturated, and have feldspathoids in their normative mineralogy. Mineral assemblages in phonolite occurrences are … See more Nepheline syenites and phonolites occur widely distributed throughout the world in Canada, Norway, Greenland, Sweden, the United Kingdom, the Ural Mountains, the Pyrenees, … See more • Woolley, A.R., Alkaline rocks and carbonatites of the world See more WebMay 8, 2024 · phonolite A fine-grained, porphyritic, extrusive, igneous rock consisting of essential alkali feldspar ( sanidine or anorthoclase ), nepheline, sodic pyroxene, and sodic … phone counsellingWebParent material of lamprophyres is probably alkaline olivine basalt . Movement of alkaline olivine basalt magma toward the surface might induce decompressive melting, and the resulting magma could be injected into fractures resulting from compressive failure . Mafic phenocrysts would have formed early, before injection how do you make cinnamon sugar pecans

"The main minerals are alkali feldspar, nepheline, clinopyroxene (±), amphibole (±), and biotite (±). Nepheline is the main feldspathoid. Quartz and orthopyroxene are absent. According to the IUGS classification nomenclature (International Union of Geological Sciences, Streckeisen, 1978), nepheline syenite has 10% < F/(F + A + P) < 60% and P/(A + P) < 10% (where F – feldspathoids, A – alkali feldspar, and P – plagioclase volume fractions). Phonolite is the fine-grained equivalent. In … " - Phonolite material
