mineral deposit - Hydrothermal solution | Britannica

Hydrothermal mineral deposits are those in which hot water serves as a concentrating, transporting, and depositing agent. They are the most numerous of all classes of deposit. Hydrothermal deposits are never formed from pure water, because pure water is a poor solvent of most ore minerals. Rather, they are formed by hot brines, making it more ...

Abstract. Major magnesite deposits are hosted either by ultramafic or sedimentary rocks. Ultramafic rock-hosted magnesite ores consist mainly of talc-magnesite rocks (Simandl and Ogden, 1999) or they form "Kraubath-type" high-grade magnesite veins and stockworks (Zachman and Johannes, 1989; Paradis and Simandl, 1999).
