Benmoreite and Argillite


Argillite and Benmoreite


Definition

Definition
An iron rich extrusive rock found as a member of the alkali basalt magma series   
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   

History
  
  

Origin
Isle of Mull, Scotland   
Unknown   

Discoverer
Ben More   
Unknown   

Etymology
From the name of discoverer, Ben More   
From Latin Argilla (clay) and -ite in English which became agrilla+ -ite = Argillite

Formation

Formation
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.   
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.
