About Trögerite
Formula:
(H3O)(UO2)(AsO4) · 3H2O
There is a considerable confusion in the literature in distinguishing amongst two independent species, (meta)hydroniumuranospinite (structure based upon autunite topology), and trögerite (structure based upon different topology, as indicated by U:As ratio equal 3:2, c.f. original description by Weissbach 1873). Locock et al. (2004) introduced a misleading assignment of trögerite to the autunite group, with the composition (H3O)2[(UO2)2(AsO4)2](H2O)6. Chernorukov et al. (2011) synthesized compound of the composition (UO2)3(AsO4)2(H2O)12, which they equalized with trögerite. Structural investigations of Locock and Burns (2002) on synthetic (UO2)3(PO4)2(H2O)4, which is based on uranophane topology, suggests, that trögerite may be based on similar topology, having a framework structure with uranium located both on sheets as well as in interlayer, similarly as e.g. phosphuranylite (Demartin et al. 1991). The chemical composition of trögerite given in original description by Weissbach (1873) suggests that these two substances are not same mineral. Recently electron microanalysis of the type material of trögerite documented neither presence of trögerite on it nor the presence of (H3O)2[(UO2)2(AsO4)2](H2O)6. All analyzed crystals belong to nováčekite (Plášil et al. in prep.)

Name:
Named by A. Weisbach in 1871 for "R. Troeger", possibly for Richard Otto Troeger [1838-1917], mining administrator at Schneeberg, Saxony, Germany. (The translation of 'Bergverwalter' (= mining administrator) may indicate a lesser position such as mine captain, mine superintendent, or shift boss.)
Possibly the arsenate analogue of 'UM1963-03-PO:HU'. Compare 'Unnamed (Hydronium-uranyl arsenate)', a chemically similar phase.
A secondary mineral usually found as crusts or aggregates of microscopic crystals. Often found growing in parallel with zeunerite.
