TL;DR: Sturmanite as discussed by the authors is an analogue of euringite and occurs on hematite-an6'b*i'ti' u, fiur_ tened dipyramidal crystals at the Black Rock mine, Republic 9f 99!rh Africa.
Abstract: . S turman i te , Cau1Fe3r , . rA l0 . lMn2t o .z ) rz .o (So+)z . r { B(oH)4} r.2(o H) n 2sHzci,'' is -i ferrtc'ii6ii,' uolon_ 99ryqniry analogue of euringite C%Al2(SOt3(OH)r2. 26Hzo, Sturmanite occurs on hematite-an6'b*i'ti' u, fiur_ tened dipyramidal crystals at the Black Rock mine, Republic 9f 99!rh Africa. f,he probable space group is pitc, a I I. I 6(3), c 21 .7 9(9)A, Z : 2. It is bipht yellow and has one perfect cleavage on {l0tO}. The dinsity is 1.847 g/cm3 (obs.), 1.855 g/cm3 (calc.). Optically stunnanite is uniaxial (+ ),.with co = 1,500, e = I .505, but some crystals have a core thar is optically (), with e = 1.497, c,s= 1.499. It is weakly dichroic with O pale green and .E paJe yellow green. The principal X-ray-diffracrion lines [d in A (intensitg@*t)] are: ?.q1q9-l(1-00), 5. 58(70X I I 0), 3. 8e(70) ( I I4), 2.7 4(s0)(3M), 2.582(60)Ql6), 2.215(50)e26, 320). Sturmanite is namea in honor of B. Darko Sturman, mineralogist at the Royal Ontario Museum.
