Magnesite Deposits of Central Ceará, Brazil

Description: From introduction: The purpose of this study was to investigate the quantity and quality of [Central Ceara, Brazil] magnesite, and the writer concludes that this group of deposits constitutes one of the major reserves of high-grade magnesite in the Western Hemisphere.
