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.
Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

All about Granodiorite and Mugearite Properties
Know all about Granodiorite and Mugearite properties here. All properties of rocks are important as they define the type of rock and its application. Granodiorite and Mugearite belong to Igneous Rocks.Texture of Granodiorite is Granular, Phaneritic whereas that of Mugearite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Granodiorite appears Veined or Pebbled and Mugearite appears Dull and Soft. The luster of Granodiorite is grainy, pearly and vitreous while that of Mugearite is not available. Granodiorite is available in black, grey, orange, pink, white colors whereas Mugearite is available in black, brown, light to dark grey colors. The commercial uses of Granodiorite are curling, gemstone, laboratory bench tops, tombstones and that of Mugearite are creating artwork.
