Near infrared (NIR), infrared (IR) spectroscopy and X-ray diffraction (XRD) have been applied to halotrichites of the formula FeAl 2 (SO 4 ) 4 ·22H 2 O and Fe 2+ Fe 23+ (SO 4 ) 4 ·22H 2 O. Comparison of the halotrichites and their starting materials has been used to give a better understanding of the bonding involved in these...
Minerals in the rosasite mineral group namely rosasite, glaucosphaerite, kolwezite, mcguinnessite have been studied by powder X-ray diffraction, scanning electron microscopy and infrared spectroscopy. X-ray diffraction shows the minerals to be complex mixtures with more than one rosasite mineral observed in each sample. SEM analysis shows the minerals to be fibrous in nature and the use of EDAX enabled...
