Lithium mineral evolution and ecology: comparison with boron and beryllium

Mineral Diversity, Complexity and Evolution Preface

Fluor-elbaite, lepidolite and Ta–Nb oxides from a pegmatite of the 3000 Ma Sinceni Pluton, Swaziland: evidence for lithium–cesium–tantalum (LCT) pegmatites in the Mesoarchean

Tinzenite, a member of the axinite group with formula revised to Ca 2 M n 4 2+ Al 4 [ B 2 Si 8 O 30 ] ( OH ) 2

Khesinite, Ca 4 Mg 2 Fe 3+ 10 O 4 [(Fe 3+ 10 Si 2 )O 36 ], a new rhönite-group (sapphirine supergroup) mineral from the Negev Desert, Israel – natural analogue of the SFCA phase

The triplite–triploidite supergroup: structural modulation in wagnerite, discreditation of magniotriplite, and the new mineral hydroxylwagnerite

Werdingite from a pegmatite at Almgjotheii, Rogaland, Norway: The role of iron in a borosilicate with a mullite-type structure

Boromullite, Al 9 BSi 2 O 19 , a new mineral from granulite-facies metapelites, Mount Stafford, central Australia: a natural analogue of a synthetic “boron-mullite”

The crystal-chemistry of aenigmatite revisited: electron microprobe data, structure refinement and Mössbauer spectroscopy of aenigmatite from Vesterøya (Norway)

Chopinite, [(Mg, Fe) 3 □](PO 4 ) 2 , a new mineral isostructural with sarcopside, from a fluorapatite segregation in granulite-facies paragneiss, Larsemann Hills, Prydz Bay, East Antarctica

Iron-rich kornerupine in sheared pegmatite from the Wanni Complex, at Homagama, Sri Lanka

Reedmergnerite and associated minerals from peralkaline pegmatite, Dara-i-Pioz, southern Tien Shan, Tajikistan

Calcian, borian sapphirine from the serendibite deposit at Johnsburg, N.Y., USA
