3. Concentrating natural phenomena, deposits, reserves and production
3.1 Magnesium concentrator phenomena
They are at the origin of sedimentary-type deposits resulting from the evaporation of seawater. The genesis of evaporites is complex, as a result of reworking, flooding, meteorological variations, leaching by rainwater or the decomposition of double salts, such as carnalite, which decomposes into sylvinite. However, the evaporitic series can be considered, from bottom to top, as the following sedimentary sequence:

Economic data
1. World magnesite production
In 2007, world mine production of magnesite totaled over 4.5 Mt (excluding the United States). It came mainly from China (1.87 Mt), Turkey (0.93 Mt), North Korea (1.85 Mt), Russia (0.35 Mt), Spain (0.15 Mt) and Greece (0.15 Mt). In addition to this production, some 10.1 Mt of magnesite were extracted from seawater and salt lakes; for Japan and the USA, production from seawater was 5...
