Archaeological Significance
Formation
Latite 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.
Novaculite forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The formation of Novaculite can be either of chemical or biological origin.

More about Latite and Novaculite
Here you can know more about Latite and Novaculite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Novaculite consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Novaculite includes Quartz, Silicon. You can also check out the list of all Igneous Rocks. When we have to compare Latite vs Novaculite, the texture, color and appearance plays an important role in determining the type of rock. Latite is available in black, brown, green, grey, pink, white colors whereas, Novaculite is available in black, brown, green, grey, red, white colors. Appearance of Latite is Rough and that of Novaculite is Glassy or Pearly. Properties of rock is another aspect for Latite vs Novaculite. The hardness of Latite is 5-5.5 and that of Novaculite is 7. The types of Latite are Rhomb porphyries whereas types of Novaculite are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Latite is white while that of Novaculite is . The specific heat capacity of Latite is 0.92 kJ/Kg K and that of Novaculite is 0.74 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Latite is heat resistant, pressure resistant whereas Novaculite is heat resistant, impact resistant, pressure resistant, wear resistant.
