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
Rhomb-porphyry is a porphyritic igneous rock with abundant wedge or lens shaped anorthoclase or feldspar phenocrysts

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

Due to some exceptional properties of Diamictite and Rhomb Porphyry, 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 Rhomb Porphyry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Diamictite and Rhomb Porphyry
Here you can know more about Diamictite and Rhomb Porphyry. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Rhomb Porphyry consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Rhomb Porphyry includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Rhomb Porphyry, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Rhomb Porphyry is available in black, brown, green, grey, pink, white colors. Appearance of Diamictite is Banded and that of Rhomb Porphyry is Rough. Properties of rock is another aspect for Diamictite vs Rhomb Porphyry. The hardness of Diamictite is 2-3 and that of Rhomb Porphyry is 5-5.5. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Rhomb Porphyry are Igneous rock. 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 Rhomb Porphyry is white. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Rhomb Porphyry is 0.92 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 Rhomb Porphyry is heat resistant, pressure resistant.
