Formation

Ijolite 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.

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.

All about Ijolite and Latite Properties

Know all about Ijolite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Ijolite and Latite belong to Igneous Rocks.Texture of Ijolite is Earthy, Granular whereas that of Latite is Aphanitic to Porphyritic. Ijolite appears Banded and Foilated and Latite appears Rough. The luster of Ijolite is greasy to dull while that of Latite is subvitreous to dull. Ijolite is available in brown, buff, cream, green, grey, pink, white colors whereas Latite is available in black, brown, green, grey, pink, white colors.
