Definition
Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%

Formation
Adamellite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma and is a variety of Monzogranite.
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.

More about Adamellite and Foidolite
Here you can know more about Adamellite and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adamellite and Foidolite consists of mineral content and compound content. The mineral content of Adamellite includes Apatite, Biotite, Chlorite, Orthoclase, Perthite, Plagioclase, Quartz, Titanite, Zircon and mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Adamellite vs Foidolite, the texture, color and appearance plays an important role in determining the type of rock. Adamellite is available in black, grey, orange, pink, white colors whereas, Foidolite is available in black, brown, green, grey, pink, white colors. Appearance of Adamellite is Veined or Pebbled and that of Foidolite is Dull. Properties of rock is another aspect for Adamellite vs Foidolite. The hardness of Adamellite is 6-7 and that of Foidolite is 1.5. The types of Adamellite are Granite whereas types of Foidolite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adamellite and Foidolite is white. The specific heat capacity of Adamellite is 0.79 kJ/Kg K and that of Foidolite is 0.79 kJ/Kg K.
