Definition
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
Hornfels is a metamorphic rock formed by the contact between mudstone or other clay rich rock, and a hot igneous body, and represents a heat altered equivalent of the original rock

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Hornfels is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Diamictite and Hornfels
Here you can know more about Diamictite and Hornfels. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Hornfels consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Hornfels includes Andalusite. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Hornfels, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Hornfels is available in brown, dark greenish - grey, green, reddish brown colors. Appearance of Diamictite is Banded and that of Hornfels is Dull. Properties of rock is another aspect for Diamictite vs Hornfels. Hardness of Diamictite and Hornfels is 2-3. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Hornfels are Biotite hornfels. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diamictite is light to dark brown while that of Hornfels is unknown. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Hornfels is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diamictite is heat resistant, impact resistant whereas Hornfels is heat resistant, impact resistant, pressure resistant.
