Formation

Formation
Trachyandesite 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.  
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

More about Trachyandesite and Jaspillite

Here you can know more about Trachyandesite and Jaspillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Trachyandesite and Jaspillite consists of mineral content and compound content. The mineral content of Trachyandesite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase and mineral content of Jaspillite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Trachyandesite vs Jaspillite, the texture, color and appearance plays an important role in determining the type of rock. Trachyandesite is available in black, brown, light to dark grey colors whereas, Jaspillite is available in red, reddish brown colors. Appearance of Trachyandesite is Dull and Soft and that of Jaspillite is Banded and Glassy. Properties of rock is another aspect for Trachyandesite vs Jaspillite. The hardness of Trachyandesite is 4-5 and that of Jaspillite is 3. The types of Trachyandesite are Basaltic Trachyandesite whereas types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Trachyandesite is light to dark brown while that of Jaspillite is white. The specific heat capacity of Trachyandesite is 0.84 kJ/Kg K and that of Jaspillite is 3.20 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Trachyandesite is heat resistant, pressure resistant, wear resistant whereas Jaspillite is heat resistant, impact resistant, wear resistant.
