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.
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 Benmoreite and Blueschist Properties
Know all about Benmoreite and Blueschist properties here. All properties of rocks are important as they define the type of rock and its application. Benmoreite belongs to Igneous Rocks while Blueschist belongs to Metamorphic Rocks.Texture of Benmoreite is Glassy, Massive, Porphyritic, Scoriaceous, Trachytic, Vesicular whereas that of Blueschist is Foliated. Benmoreite appears Rough and Dull and Blueschist appears Dull and Banded. The luster of Benmoreite is earthy while that of Blueschist is dull. Benmoreite is available in black, brown, light to dark grey colors whereas Blueschist is available in blue, bluish - grey, purple, shades of blue colors. The commercial uses of Benmoreite are commemorative tablets, creating artwork, curling and that of Blueschist are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
