    wgnhs.wisc.edu/minerals/hisingerite Formula: Fe 2 Si 2 O 5 (OH) 4.2H 2 O Monoclinic Description: Hisingerite is common as an alteration product in many iron-rich rocks.Although reported in only one locality in the state, it is likely present in a number of other places. Its earthy character, yellow brown streak and association with iron oxides of similar appearance makes it easy to overlook.
