Grand Rapids, Michigan
1988 Matrix Secondary Mineral(s) Probably named for the Greek word gypsos meaning plaster. Gypsum mining in Grand Rapids started in the spring of 1843 when Richard E. Butterworth uncovered a layer of it while plowing. This turned into the Grand Rapids Gypsum Co. in 1860 (and bought by Domtar Industries Inc. in 1981), which is the oldest continuously operating gypsum mine in in the world. The Alabastine mine was a competetor who's output was used to make sparkling/glittering alabastine paint.

Seathwaite mine
Borroudale, Cumbria, England
acquired 1997 Matrix Secondary Mineral(s) The Seathwaite mine supplied the first ever pencil factory in Keswick, England. It was named from the Greek verb graphein meaning to write by Abraham Gottlob Werner in 1789 according to the Encyclopaedia Britannica.
According to: http://www.pencils.com/history.html "Graphite came into widespread in the 16th century, following the discovery of a large graphite deposit in Borrowdale, England. As the story goes, a passerby found bits of shiny, black graphite clinging to the roots of a fallen tree. The whole countryside was abuzz with talk about this mysterious mineral, which soon came to be known as "plumbago" or, more commonly, "Blacklead."
The traditional name for Borrowdale graphite in the local nomenclature was "wadd". (Molly Lefebure, Cumberland Heritage, 1970)
Dana's 6th says that the name plumbago originated with Brommell in 1739 and that the earlier use of the name by Agricola was for galena. Dana's 1st has graphite meaning "I write" but Dana's 6th has it meaning "to write". Dana gives credit to Werner for the name graphite.

It has been claimed that graphite from the mine in Cumbria gave an interesting term to the English vocabulary. When it was discovered that you could make writing instruments from the processed graphite, the discovery was a major advance in communication and espionage. The Crown forbid the unauthorized mining and exportation of graphite. From the dumps of the graphite mine, intrepid souls secretly would try to collect and extract the graphite and bring the material to the big city, London, where they would surreptitiously try to sell their contraband. The authorities would easily be able to arrest the miscreants because of the graphite stains on their hands; from these soiled hands we get "black market".
