1.1 Definition

Shonkinite is a rare, dark-coloured and intrusive igneous rock which contains augite and orthoclase feldspar as its primary constituents

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

1.3 Etymology

From the name of Shonkin Sag ranges in the Highwood Mountains of north-central Montana, US

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

5 Formation

5.1 Formation

Shonkinites 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.
