The boron isotope composition of calcium carbonate shells of marine organisms has the unique potential to record surface ocean pH, allowing the calculation of atmospheric pCO 2 due to the established relationship between pH and the partial pressure of (atmospheric) CO2 (pCO 2).This "paleo-pH meter" allows scientists to produce a record of the natural fluctuations of atmospheric pCO 2 over ...

Boron is a chemical element with the symbol B and atomic number 5. In its crystalline form it is a brittle, dark, lustrous metalloid; in its amorphous form it is a brown powder. As the lightest element of the boron group it has three valence electrons for forming covalent bonds, resulting many compounds such as boric acid, the mineral borax, and the ultra-hard crystal boron carbide.

The ore is crushed and blended to a concentration of 8.6% boron oxide. The datolite is not soluble and the ore is washed to remove gangue after crushing. Decahydrate borax is also produced by the reaction of boric acid with sodium carbonate (soda ash) as follows: 4H3BO3 + Na2CO3 + 4H2O ⇒ Na2B4O7·10H2O + CO2
