Definition
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%
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
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.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

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