Argillite and Granodiorite


Granodiorite and Argillite


Definition

Definition
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  
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite

Formation

Formation
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.  
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

All about Argillite and Granodiorite Properties

Know all about Argillite and Granodiorite properties here. All properties of rocks are important as they define the type of rock and its application. Argillite belongs to Sedimentary Rocks while Granodiorite belongs to Igneous Rocks.Texture of Argillite is Clastic, Polished whereas that of Granodiorite is Granular, Phaneritic. Argillite appears Rough and Dull and Granodiorite appears Veined or Pebbled. The luster of Argillite is waxy and dull while that of Granodiorite is grainy, pearly and vitreous. Argillite is available in dark grey to black, pink, red, white colors whereas Granodiorite is available in black, grey, orange, pink, white colors. The commercial uses of Argillite are fire resistant, used to manufracture paperweights and bookends and that of Granodiorite are curling, gemstone, laboratory bench tops, tombstones.
