2019/11/5· Magnesium, manganese, strontium, and barium are four commonly studied metals in bivalve shells and are frequently utilized as proxies for environmental conditions (Freitas et al., 2005; Immenhauser et al., 2005; Klein et al., 1996a; Poulain et al., 2015; ).

It''s Elemental - The Element Barium

Barium is pronounced as BAR-ee-em. History and Uses: Barium was first isolated by Sir Humphry Davy, an English chemist, in 1808 through the electrolysis of molten baryta (BaO). Barium is never found free in nature since it reacts with oxygen in the air, forming barium oxide (BaO), and with water, forming barium hydroxide (Ba (OH) 2) and hydrogen
