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
From the place of origin called Shoshone riverin Wyoming
Durable Rock, Medium Hardness Rock

Decorative Aggregates, Homes, Interior Decoration
As Building Stone, As Facing Stone
As Dimension Stone, Cobblestones, Rail Track Ballast, Roadstone
Cemetery Markers, Creating Artwork
Intermediate volcanic rock
Has High structural resistance against erosion and climate, Very fine grained rock
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.

Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat
From French, Latin lignum wood + -ite1

for Road Aggregate, Steel Production
Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite
Generally rough to touch, Helps in production of Heat and Electricity, Used as fossil fuel
Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.
