Archaeological Significance
Formation
Hornblendite 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.
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

More about Hornblendite and Whiteschist
Here you can know more about Hornblendite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Whiteschist consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite and mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Hornblendite vs Whiteschist, the texture, color and appearance plays an important role in determining the type of rock. Hornblendite is available in black, brown, green, grey colors whereas, Whiteschist is available in green, grey, white colors. Appearance of Hornblendite is Foliated and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Hornblendite vs Whiteschist. The hardness of Hornblendite is 6-7 and that of Whiteschist is 1.5. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite whereas types of Whiteschist are -. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hornblendite is white to grey while that of Whiteschist is white. The specific heat capacity of Hornblendite is 0.84 kJ/Kg K and that of Whiteschist 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.Hornblendite is heat resistant, pressure resistant, wear resistant whereas Whiteschist is heat resistant.
