(2000)	10.2138/am-2000-8-925	AM85_1307	A syn-sedimentary exhalative origin in connection with the Jurassic oceanic ridge volcanism is proposed for these deposits.
Michelle_821	65	2.6	Tertiary	Age of recrystallization		Cabalzarite	As	3211	Falotta, Tinizong (Tinzen), Oberhalbstein (Surses; Sursass), Albula Valley, Grisons, Switzerland	Falotta Deposit	Brugger et al. (2000)	10.2138/am-2000-8-925	AM85_1307	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.
Michelle_822	0	0	Recent	Age of oxalate mineralization	high	Lindbergite, Falottaite		3211	Falotta, Tinizong (Tinzen), Oberhalbstein (Surses; Sursass), Albula Valley, Grisons, Switzerland	Falotta Deposit	Graeser and Gabriel (2016)		SS3_20	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.
