Definition
Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent
  
Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides

Formation
Teschenite 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.
  
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.

More about Teschenite and Mugearite
Here you can know more about Teschenite and Mugearite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Teschenite and Mugearite consists of mineral content and compound content. The mineral content of Teschenite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Teschenite vs Mugearite, the texture, color and appearance plays an important role in determining the type of rock. Teschenite is available in dark grey to black colors whereas, Mugearite is available in black, brown, light to dark grey colors. Appearance of Teschenite is Veined and Shiny and that of Mugearite is Dull and Soft. Properties of rock is another aspect for Teschenite vs Mugearite. The hardness of Teschenite is 7 and that of Mugearite is 6. The types of Teschenite are Not Available whereas types of Mugearite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Teschenite is black while that of Mugearite is white to grey.
