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
Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

Diamictite vs Pumice Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Diamictite vs Pumice characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diamictite and Properties of Pumice. Learn more about Diamictite vs Pumice in the next section. The interior uses of Diamictite include Decorative aggregates and Interior decoration whereas the interior uses of Pumice include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Diamictite and Pumice, they have various applications in construction industry. The uses of Diamictite in construction industry include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone and that of Pumice include As dimension stone, Cement manufacture, For road aggregate, In landscaping and horticulture, Making natural cement, Production of lightweight concrete blocks.
More about Diamictite and Pumice
Here you can know more about Diamictite and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Pumice consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Pumice, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Diamictite is Banded and that of Pumice is Vesicular. Properties of rock is another aspect for Diamictite vs Pumice. The hardness of Diamictite is 2-3 and that of Pumice is 6. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Pumice are Scoria. 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 Pumice is white, greenish white or grey. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Pumice is 0.87 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 Pumice is impact resistant, pressure resistant.
