Summary

Ruizite is a new mineral found in the mesogene calc-silicate assemblage at the Christmas mine, Gila County, Arizona. Occurs with kinoite, apophyllite, smectite, and junitoite. Colour is orange inclining to brown with pale streak, H = 5, Sp. Gr. meas. = 2·9. Crystals monoclinic 2/m, elongate on [010]; a = 11·95 Å, b = 6·17, c = 9·03, β = 91° 22½′. Probable space group P21/c with Z = 4 giving Dcalc = 2·997. Strongest lines are 11·951 Å(10), 4·190 (7), 3·116 (6), 5·092 (5), 3·644 (4), 2·951 (4), 2·591 (4), 2·132 (4). Indices are α = 1·663, β = 1·715 ‖ [010], γ = 1·734, 44° to [001] in obtuse β; 2Vα = 60·2°; inclined dispersion p > v strong. Twinned on {100}. Analysis by wet methods gave CaO = 20·57%, Mn2O3 = 23·42, SiO2 = 39·14, H2O = 16·0 leading to or CaMn3+ (SiO3)2(OH). 2H2O.

Named for its discoverer, Joe Ana Ruiz of Mammoth, Arizona
