Shoshonite and Diamictite


Diamictite and Shoshonite


Definition

Definition
Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass  
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

Formation
Shoshonite 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 Shoshonite and Diamictite Properties

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