caption_attribution_description: English: Iowaite (Size: 1.4 cm x 0.9 cm x 0.2 cm) Locality: Palabora mine (Foscor open pit; PMC mine), Loolekop, Phalaborwa, Limpopo Province, South Africa Original description: Iowaite is a rare Mg-Fe hydroxide of the Hydrotalcite Group. This is a very fine, two-sided compound tabular crystal with high lustre and nicely translucent edges. The world's finest examples of the species come from this large open pit mine. Deutsch: Iowait (Größe: 1,4 cm x 0,9 cm x 0,2 cm) Fundort: Palabora Mine (Foscor open pit; PMC mine), Loolekop, Phalaborwa, Provinz Limpopo, Südafrika Iowait ist ein seltenes Mg-Fe-Hydroxid der Hydrotalcitgruppe. Dies ist eine gut ausgebildete Gruppe aus beidseitig miteinander verbundenen, tafeligen Kristallen mit hohem Glanz und durchscheinenden Ecken.
context_page_description: Georgius Agricola is considered the 'father of mineralogy'. Nicolas Steno founded the stratigraphy, the geology characterizes the rocks in each layer and the mineralogy characterizes the minerals in each rock. The chemical elements were discovered in identified minerals and with the help of the identified elements the mineral crystal structure could be described. One milestone was the discovery of the geometrical law of crystallization by René Just Haüy, a further development of the work by Nicolas Steno and Jean-Baptiste L. Romé de l'Isle. Important contributions came from some Saxon "Bergraths"/ Freiberg Mining Academy: Johann F. Henckel, Abraham Gottlob Werner and his students. Other milestones were the notion that metals are elements too and the periodic table of the elements by Dmitri Ivanovich Mendeleev. The overview of the organic bonds by Kekulé was necessary to understand the silicates, first refinements described by Bragg and Machatschki; and it was only possibly to understand a crystal structure with Dalton's atomic theory, the notion of atomic orbital and Goldschmidt's explanations.
