Definition
Trachyandesite is an extrusive igneous rock.
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

Archaeological Significance
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.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

More about Trachyandesite and Diamictite
Here you can know more about Trachyandesite and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Trachyandesite and Diamictite 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 Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Trachyandesite vs Diamictite, 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, Diamictite is available in brown, buff colors. Appearance of Trachyandesite is Dull and Soft and that of Diamictite is Banded. Properties of rock is another aspect for Trachyandesite vs Diamictite. The hardness of Trachyandesite is 4-5 and that of Diamictite is 2-3. The types of Trachyandesite are Basaltic Trachyandesite whereas types of Diamictite are Bedded Diamictite and Laminated Diamictite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Trachyandesite and Diamictite is light to dark brown. The specific heat capacity of Trachyandesite is 0.84 kJ/Kg K and that of Diamictite is 0.75 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 Diamictite is heat resistant, impact resistant.
