1 Definition

1.1 Definition

Nepheline Syenite is a holocrystalline plutonic rock resembling syenite but containing nepheline and lacking quartz

Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate

1.2 History

1.3 Etymology

From origin of a Palaeozoic nepheline syenite from northern Shanxi Province, China

From Latin Argilla (clay) and -ite in English which became agrilla+ -ite = Argillite

5 Formation

5.1 Formation

Nepheline Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

An argillite is a fine-grained sedimentary rock mainly composed of clay particles which forms from lithified muds which contain variable amounts of silt-sized particles.

Nepheline Syenite vs Argillite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Nepheline Syenite and Argillite Reserves. Nepheline Syenite is a holocrystalline plutonic rock resembling syenite but containing nepheline and lacking quartz. Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes.
