Definition
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism
Monzogranite is a type of igneous rock and belongs to biotite granite rocks that are considered to be the final fractionation product of magma

Formation
Slate is a low grade metamorphic rock that is generally formed by metamorphosis of mudstone or shale, under relatively low pressure and temperature conditions.
Monzogranite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Slate and Monzogranite Properties
Know all about Slate and Monzogranite properties here. All properties of rocks are important as they define the type of rock and its application. Slate belongs to Metamorphic Rocks while Monzogranite belongs to Igneous Rocks.Texture of Slate is Foliated whereas that of Monzogranite is Porphyritic. Slate appears Dull and Monzogranite appears Veined or Pebbled. The luster of Slate is dull while that of Monzogranite is dull to grainy with sporadic parts pearly and vitreous. Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue colors whereas Monzogranite is available in black, grey, orange, pink, white colors. The commercial uses of Slate are blackboards, commemorative tablets, laboratory bench tops, standard material for the bed of billiard table, standard material for the beds of pool and snooker table, tombstones, used in aquariums, writing slates and that of Monzogranite are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
