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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

More about Rhomb Porphyry and Turbidite
Here you can know more about Rhomb Porphyry and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Rhomb Porphyry and Turbidite consists of mineral content and compound content. The mineral content of Rhomb Porphyry includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Rhomb Porphyry vs Turbidite, 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, Turbidite is available in black, brown, green, grey, pink colors. Appearance of Rhomb Porphyry is Rough and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Rhomb Porphyry vs Turbidite. The hardness of Rhomb Porphyry is 5-5.5 and that of Turbidite is 3. The types of Rhomb Porphyry are Igneous rock whereas types of Turbidite are Sedimentary rock. 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 Turbidite is white, greenish white or grey.
