Features
Constitutes upper part of the Earth's mantle, Generally rough to touch, Host rock for Diamond, Is one of the oldest rock
Available in Lots of Colors and Patterns, It is One of the Oldest, Strongest and Hardest Rock
Archaeological Significance
Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.
Alkali fledspar granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

More about Peridotite and Alkali Feldspar Granite
Here you can know more about Peridotite and Alkali Feldspar Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Alkali Feldspar Granite consists of mineral content and compound content. The mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Alkali Feldspar Granite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Alkali Feldspar Granite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Alkali Feldspar Granite is available in black, grey, orange, pink, white colors. Appearance of Peridotite is Rough and Shiny and that of Alkali Feldspar Granite is Veined or Pebbled. Properties of rock is another aspect for Peridotite vs Alkali Feldspar Granite. The hardness of Peridotite is 5.5-6 and that of Alkali Feldspar Granite is 6-7. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Alkali Feldspar Granite are Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite and Alkali Feldspar Granite is white. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Alkali Feldspar Granite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Peridotite is heat resistant, pressure resistant, wear resistant whereas Alkali Feldspar Granite is heat resistant, wear resistant.
