Definition
Rhyodacite is an extrusive volcanic rock intermediate in composition between dacite and rhyolite
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

Formation
Rhyodacite 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 Rhyodacite and Diamictite
Here you can know more about Rhyodacite and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Rhyodacite and Diamictite consists of mineral content and compound content. The mineral content of Rhyodacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon 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 Rhyodacite vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Rhyodacite is available in black to grey, dark greenish - grey colors whereas, Diamictite is available in brown, buff colors. Appearance of Rhyodacite is Skeletal and that of Diamictite is Banded. Properties of rock is another aspect for Rhyodacite vs Diamictite. The hardness of Rhyodacite is 5.5-6 and that of Diamictite is 2-3. The types of Rhyodacite are Not Available 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 Rhyodacite is black while that of Diamictite is light to dark brown. The specific heat capacity of Rhyodacite is 1.12 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.Rhyodacite is heat resistant whereas Diamictite is heat resistant, impact resistant.
