Definition
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

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.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

All about Granodiorite and Oolite Properties
Know all about Granodiorite and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Granodiorite belongs to Igneous Rocks while Oolite belongs to Sedimentary Rocks.Texture of Granodiorite is Granular, Phaneritic whereas that of Oolite is Clastic or Non-Clastic. Granodiorite appears Veined or Pebbled and Oolite appears Rounded and Rough. The luster of Granodiorite is grainy, pearly and vitreous while that of Oolite is pearly to shiny. Granodiorite is available in black, grey, orange, pink, white colors whereas Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. The commercial uses of Granodiorite are curling, gemstone, laboratory bench tops, tombstones and that of Oolite are creating artwork, jewelry, used in aquariums.
