Barite

open access: yes, 1988
More than 150 occurrences or deposits of barite (barium sulphate, BaSO 4) have been recorded in Canada; however, deposits of economic significance are confined largely to Newfoundland, Nova Scotia, Ontario and British Columbia. There are three main producers of barite at present: one with a mine at Brookfield, N.S., another with mines near Matachewan ...

Barium isotope (re-)equilibration in the barite-fluid system and its implications for marine barite archives [PDF]

open access: yes
Variations in the Ba isotopic composition of seawater are largely driven by the extent of barite precipitation in the marine photic zone and replenishment of Ba by upwelling and/or continental inputs.
