Definition
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
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%

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

All about Diamictite and Foidolite Properties
Know all about Diamictite and Foidolite properties here. All properties of rocks are important as they define the type of rock and its application. Diamictite belongs to Sedimentary Rocks while Foidolite belongs to Igneous Rocks.Texture of Diamictite is Clastic whereas that of Foidolite is Earthy. Diamictite appears Banded and Foidolite appears Dull. The luster of Diamictite is grainy, pearly and vitreous while that of Foidolite is subvitreous to dull. Diamictite is available in brown, buff colors whereas Foidolite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Diamictite are commemorative tablets, creating artwork, production of lime and that of Foidolite are cemetery markers, commemorative tablets, creating artwork.
