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
Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities

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.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

More about Teschenite and Scoria
Here you can know more about Teschenite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Teschenite and Scoria consists of mineral content and compound content. The mineral content of Teschenite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Teschenite vs Scoria, 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, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Teschenite is Veined and Shiny and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Teschenite vs Scoria. The hardness of Teschenite is 7 and that of Scoria is 5-6. The types of Teschenite are Not Available whereas types of Scoria are Not Available. 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 Scoria is white. The specific heat capacity of Teschenite is Not Available and that of Scoria is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Teschenite is impact resistant, pressure resistant, wear resistant whereas Scoria is heat resistant, impact resistant, pressure resistant, wear resistant.
