The Mineral Evolution database is currently under development.
The goal of this page is to present localities at which the mineral is found, and estimates of the oldest possible geologic age of the minerals at these localities.
This mineral is using an age reported as an element mineralization period.
O
This mineral is using an age calculated from all data at the locality.
R
The age displayed for this mineral originates from a different, non-child locality.
P
The age displayed for this mineral is the range of ages for this mineral at all of this locality's children.
This mineral's age has not yet been recorded.
This Mineral list contains entries from this locality, including sub-localities. Minerals in bold are reported by mindat.org as occurring directly at this locality, and do not occur at any children (sublocalities) of this locality.Elements at this locality, including sub-localities: AlAsBBaBeCCaCeCoCuFFeHKMgMnNaNiOPbSSbSiSrTiZnElements from minerals reported directly at this locality: Structural Groups for minerals in this locality:
A small Mn-deposit was excavated at the Falotta mine during World War II. Falotta belongs to the numerous Mn-occurrences embedded in the radiolarites, which overlay the MORB-basalts of the Platta Nappe in the Swiss Alps

The sedimentary ores recrystallized during the regional Alpine metamorphism under lowest greenschist facies conditions (≤325 °C, 3–5 kb). Together with other arsenates, cabalzarite documents the mobility of As during the retrograde stage of the Tertiary Alpine metamorphism under lowest to sub-greenschist facies conditions.
A natural occurrence of Mn oxalate trihydrate has been recorded from Falotta, Oberhalbstein, Grisons, Switzerland. The mineral occurs on small quartz crystals, associated with braunite and other Mn minerals. Presumably, the mineral formed by a reaction of humic acids with the primary Mn ore. Falottaite easily dehydrates to form Lindbergite.
