Boogardie quarry
From Wikipedia, the free encyclopedia
Boogardie quarry is a quarry on Boogardie Station, 35 km from Mount Magnet in the Mid West region of Western Australia, that is a location of a rare deposit of orbicular granite.
The station is the location of a quarry with the incidence of orbicular granite.[1][2]
The quarry and its contents were a feature item in The Australian geologist newsletter, as "National Rock Garden — Boogardie orbicular granite GSA Rock of the Month — March 2013".[3]
The granite sphere at the Mines Department core library in Carlisle was donated by Mark Creasy in 2004.[4][5]
Another sphere containing the granite is located in Forrest Place in Perth.
