Archaeological Significance
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.
Latite 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 Latite Properties
Know all about Mugearite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Mugearite and Latite belong to Igneous Rocks.Texture of Mugearite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Latite is Aphanitic to Porphyritic. Mugearite appears Dull and Soft and Latite appears Rough. The luster of Mugearite is while that of Latite is subvitreous to dull. Mugearite is available in black, brown, light to dark grey colors whereas Latite is available in black, brown, green, grey, pink, white colors. The commercial uses of Mugearite are creating artwork and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
