This dolomite #quarry operated from 1899-1951 and was owned by the Dominion Iron and Steel Company (acronym: DISCO!). The #mineral dolomite has many uses, including for acid neutralization in the chemical industry, in stream restoration projects and as a soil conditioner.

DISCO made steel with #CapeBreton #coal and #iron from #Newfoundland in #Sydney's #WhitneyPier neighbourhood (named for Henry Melville Whitney, DISCO's president). #Steel is iron and carbon, and the carbon is derived from coal.

This particular spikefren is from Adelaide Mine, Tasmania, sticking with “everything cute in Australia can secretly kill you” theme.

#Fluorite: a honkin’ massive cube of calcium fluorite with that particular dull-waxy translucence I wanna pet so bad.
No UV light to see if it’d fluoresce pretty colours for me.
From Nikolaevskiy Mine in Russia where hot sulfide solutions crystallized in limestone caverns.
