Formation
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.
Foidolites is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Mugearite and Foidolite Properties
Know all about Mugearite and Foidolite properties here. All properties of rocks are important as they define the type of rock and its application. Mugearite and Foidolite belong to Igneous Rocks.Texture of Mugearite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Foidolite is Earthy. Mugearite appears Dull and Soft and Foidolite appears Dull. The luster of Mugearite is not available while that of Foidolite is subvitreous to dull. Mugearite is available in black, brown, light to dark grey colors whereas Foidolite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Mugearite are creating artwork and that of Foidolite are cemetery markers, commemorative tablets, creating artwork.
