Definition
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite
Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature

Formation
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

All about Granodiorite and Blueschist Properties
Know all about Granodiorite and Blueschist properties here. All properties of rocks are important as they define the type of rock and its application. Granodiorite belongs to Igneous Rocks while Blueschist belongs to Metamorphic Rocks.Texture of Granodiorite is Granular, Phaneritic whereas that of Blueschist is Foliated. Granodiorite appears Veined or Pebbled and Blueschist appears Dull and Banded. The luster of Granodiorite is grainy, pearly and vitreous while that of Blueschist is dull. Granodiorite is available in black, grey, orange, pink, white colors whereas Blueschist is available in blue, bluish - grey, purple, shades of blue colors. The commercial uses of Granodiorite are curling, gemstone, laboratory bench tops, tombstones and that of Blueschist are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
