Archaeological Significance
Formation
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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.

All about Benmoreite and Mudstone Properties
Know all about Benmoreite and Mudstone properties here. All properties of rocks are important as they define the type of rock and its application. Benmoreite belongs to Igneous Rocks while Mudstone belongs to Sedimentary Rocks.Texture of Benmoreite is Glassy, Massive, Porphyritic, Scoriaceous, Trachytic, Vesicular whereas that of Mudstone is Clastic. Benmoreite appears Rough and Dull and Mudstone appears Rough and Dull. The luster of Benmoreite is earthy while that of Mudstone is dull. Benmoreite is available in black, brown, light to dark grey colors whereas Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. The commercial uses of Benmoreite are commemorative tablets, creating artwork, curling and that of Mudstone are creating artwork, pottery.
