Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

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.
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

Latite vs Shale Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Latite vs Shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Latite and Properties of Shale. Learn more about Latite vs Shale in the next section. The interior uses of Latite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Shale include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Latite and Shale, they have various applications in construction industry. The uses of Latite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Shale include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Latite and Shale
Here you can know more about Latite and Shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Shale consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Latite vs Shale, 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, Shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Latite is Rough and that of Shale is Muddy. Properties of rock is another aspect for Latite vs Shale. The hardness of Latite is 5-5.5 and that of Shale is 3. The types of Latite are Rhomb porphyries whereas types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Latite and Shale is white. The specific heat capacity of Latite is 0.92 kJ/Kg K and that of Shale is 0.39 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 Shale is heat resistant, impact resistant.
