Definition
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite

Archaeological Significance
Formation
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.
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 Mudstone and Granodiorite Properties
Know all about Mudstone and Granodiorite properties here. All properties of rocks are important as they define the type of rock and its application. Mudstone belongs to Sedimentary Rocks while Granodiorite belongs to Igneous Rocks.Texture of Mudstone is Clastic whereas that of Granodiorite is Granular, Phaneritic. Mudstone appears Rough and Dull and Granodiorite appears Veined or Pebbled. The luster of Mudstone is dull while that of Granodiorite is grainy, pearly and vitreous. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Granodiorite is available in black, grey, orange, pink, white colors. The commercial uses of Mudstone are creating artwork, pottery and that of Granodiorite are curling, gemstone, laboratory bench tops, tombstones.
