Abstract

Two samples of hydrotalcite, probably worked on by Carl Christian Hochstetter, have been discovered in the Museum fur Naturkunde Berlin and given neotype status by the IMA CNMNC (proposal 15-J). The two samples from Snarum, Norway, have been reanalysed and give Mg_5.84Al_2.07Fe_0.09(OH)₁₆(CO₃)_1.08 · 4H₂O and Mg_5.75Al_2.21Fe_0.04(OH)₁₆(CO₃)_1.12· 4H₂O. Both samples have a mix of the two polytypes 3R/2H in the ratio of 69.2/30.8 and 69.5/30.5%. A discussion of hydrotalcite and hydrotalcite-like phase occurrences in the literature is also presented.
