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

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

More about Rhomb Porphyry and Diamictite
Here you can know more about Rhomb Porphyry and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Rhomb Porphyry and Diamictite consists of mineral content and compound content. The mineral content of Rhomb Porphyry includes Alkali feldspar, Biotite, Plagioclase, Pyroxene 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 Rhomb Porphyry vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Rhomb Porphyry is available in black, brown, green, grey, pink, white colors whereas, Diamictite is available in brown, buff colors. Appearance of Rhomb Porphyry is Rough and that of Diamictite is Banded. Properties of rock is another aspect for Rhomb Porphyry vs Diamictite. The hardness of Rhomb Porphyry is 5-5.5 and that of Diamictite is 2-3. The types of Rhomb Porphyry are Igneous rock 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 Rhomb Porphyry is white while that of Diamictite is light to dark brown. The specific heat capacity of Rhomb Porphyry is 0.92 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.Rhomb Porphyry is heat resistant, pressure resistant whereas Diamictite is heat resistant, impact resistant.
