...Nikita V. Chukanov; Gerhard Möhn; Igor V. Pekov; Dmitriy I. Belakovskiy; Yana V. Bychkova; Vladislav V. Gurzhiy; Joachim A. Lorenz Abstract The new mineral okruschite (IMA No. 2013–097), the arsenate analogue of roscherite, was discovered in a hydrothermal vein cross-cutting rhyolite exposed...

...Daniel Atencio; Paulo A. Matioli; Jason B. Smith; Nikita V. Chukanov; José M.V. Coutinho; Ramiza K. Rastsvetaeva; Steffen Möckel Abstract Footemineite, ideally Ca 2 Mn 2+ □Mn 2 2+ Mn 2 2+ Be 4 (PO 4 ) 6 (OH) 4 ·6H 2 O, triclinic, is a new member of the roscherite group. It occurs on thin...

... roscherite. On l’a trouvé dans des poches d’une pegmatite granitique exploitée à la mine Sapucaia (Proberil), Sapucaia do Norte, comté de Galiléia, Minas Gerais, au Brésil, en association avec albite, muscovite, cyrilovite et meurigite.La ruifrancoïte se présente en aiguilles ou en plaquettes entre 1...

...Marie Louise Lindberg Abstract New spectrographic and chemical data for roscherite from the Sapucaia pegmatite mine, Minas Gerais, Brazil, from the Nevel Quarry at Newry, Maine, and from the type locality at Greifenstein, Saxony, show that roscherite is a beryllium mineral with formula (Ca, Mn, Fe...

... in beryl along with roscherite, montgomeryite, robertsite, mitridatite, whitlockite, and englishite. It occurs as colorless to white spear-shaped blades up to 0.4 × 0.1 × 0.04 mm, as sheaf- and bow tie–like aggregates, and as compact radial sprays to 2 mm in diameter. Individual crystals are flattened...

... in small crevices in cleavelandite associated with monoclinic roscherite and minor eosphorite. It is named in honor of Richard V. Gaines. R = 0.055 for 1072 independent reflections. Eight atoms occur in the asymmetric unit of structure and five of these are disordered. Be, P, and 0(3) are half-occupied...

...-like fibers became available during the study of roscherite, (Ca, Mn, Fe) 3 Be 3- (PO 4 ) 3 (OH) 3 · 2H 2 O, another beryllium phosphate from the same locality, the Sapucaia pegmatite mine, Minas Gerais, Brazil (Lindberg, 1958, Fig. 1). The symmetry relationships of faheyite have been reinvestigated...

..., ferrisicklerite, hureaulite, vivianite, strengite, metastrengite, childrenite, variscite, frondelite, faheyite, moraesite, triphylite, montebrasite, roscherite, and apatite. Other accessory minerals are spodumene, beryl, tourmaline, and sulfides. Quartz, perthite, albite, and muscovite are the essential minerals...

...} are noted, and a new habit tabular on {0001} is described. Roscherite, hitherto known only from Ehrenfriedcrsdorf, Saxony, is noted from two new localities: the Nevel mine, Newry, Maine, and Black Mountain, Rumford, Maine. The mineral occurs as fibrous botryoidal masses with albite in pegmatite...

... and muscovite appear to be metasomatised. Pink masses of väyrynenite occur at the area of interaction of lithiophilite with altered beryl. Beryllonite, roscherite, moraesite and hydroxylherderite also occur in this assemblage. Raspberry-red pezzottaite is found near a small pollucite pod and an altered...

...” = bavenite from Strzegom, Poland) and some phosphates, such as roscherite. Application of emission spectrographic analysis was particularly instrumental in unveiling the presence of Be, which was commonly included with Al in classical wet chemical analysis. Chances of unmasking additional new minerals...
