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
Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Picrite 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 vs Picrite 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 Picrite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diamictite and Properties of Picrite. Learn more about Diamictite vs Picrite in the next section. The interior uses of Diamictite include Decorative aggregates and Interior decoration whereas the interior uses of Picrite include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Diamictite and Picrite, 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 Picrite include As a sintering agent in steel industry to process iron ore, Cement manufacture, For road aggregate, Manufacture of magnesium and dolomite refractories, Roadstone, Used for flooring, stair treads, borders and window sills..
More about Diamictite and Picrite
Here you can know more about Diamictite and Picrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Picrite consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Picrite, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors. Appearance of Diamictite is Banded and that of Picrite is Rough and Shiny. Properties of rock is another aspect for Diamictite vs Picrite. The hardness of Diamictite is 2-3 and that of Picrite is 6.8. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Picrite are Oceanite. 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 Picrite is white, greenish white or grey. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Picrite is 0.88 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 Picrite is heat resistant.
