The name itself is derived from the Finnish words "ruoste" (rust) and "solu" (cell or grain), suggesting a granular or cellular structure with a rusty hue.
These formations are typically found in areas with historical iron ore deposits or where iron-rich groundwater
Geologists study rustosoluista to understand past environmental conditions, particularly regarding the presence and movement of iron
