Al(OH)3 |
Probably precipitated from high-aluminum gels on carbonates at pH > 5.8 (Hatrurim Formation, Israel); as weathered crusts on amphiboles and pyroxenes (Dnieper region, Russia); in ba uxites. |
Valid Species (Pre-IMA) 1928 |
In the Hatrurim Formation, Israel. From an undefined area in the Dnieper region, and in the Listvennoye deposit, Yenisei Ridge, Siberia, Russia. Link to MinDat.org Location Data. |
The artificial compound is thought to have been named for the 19th-century German metallurgist Karl J. Bayer; the name was then applied to the natural mineral. |
