Formation
Foidolites 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.
  
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

The uses of Foidolite in construction industry include As dimension stone, Cement manufacture, For road aggregate and that of Oolite include Cement manufacture, Cobblestones, Landscaping.
More about Foidolite and Oolite
Here you can know more about Foidolite and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Oolite consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Foidolite vs Oolite, the texture, color and appearance plays an important role in determining the type of rock. Foidolite is available in black, brown, colourless, green, grey, pink, white colors whereas, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Foidolite is Dull and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Foidolite vs Oolite. The hardness of Foidolite is 1.5 and that of Oolite is 3-4. The types of Foidolite are Not Available whereas types of Oolite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Foidolite and Oolite is white. The specific heat capacity of Foidolite is Not Available and that of Oolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Foidolite is heat resistant, wear resistant whereas Oolite is heat resistant, wear resistant.
