Definition

Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions

Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

Formation

Lherzolite 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.

Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

All about Lherzolite and Diamictite Properties

Know all about Lherzolite and Diamictite properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite belongs to Igneous Rocks while Diamictite belongs to Sedimentary Rocks.Texture of Lherzolite is Grenue whereas that of Diamictite is Clastic. Lherzolite appears Glassy, Vesicular and Foilated and Diamictite appears Banded. The luster of Lherzolite is subvitreous to dull while that of Diamictite is grainy, pearly and vitreous. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Diamictite is available in brown, buff colors.
