An exciting find at Krokodillen: phyllosilicates

These minerals primarily form by extensive interactions between basaltic rocks and liquid water. They are excellent at preserving organic materials, if present, by adsorbing them or encapsulating them within their mineral structure.

Imogolite (Pedology 🟤)

Imogolite is an aluminium silicate clay mineral with the chemical formula Al2SiO34. It occurs in soils formed from volcanic ash and was first described in 1962 for an occurrence in Uemura, Kumamoto prefecture, Kyushu Region, Japan. Its name originates from the Japanese word imogo, which refers to the brownish yellow soil derived from volcanic ash. It ...
