Sixteen unpublished analyses of Broken Hill manganese silicates (two pyrox‐mangite, one rhodonite, four hedenbergite, and nine bustamite) from the papers of the late Dr W. T. Schaller are presented. They have been complemented with additional analyses by the electron microprobe to define the compositional fields of these minerals. Data are provided on the relationship of these minerals with tephroite and garnet. The occurrence of roepperite (zincian tephroite) at Broken Hill is discredited, and its validity is doubtful. Dannemorite from Broken Hill has a composition close to Mn2(Fe,Mg)5Si8O22(OH)2, and can be considered a valid amphibole subspecies.

At last! The long-promised and eagerly-awaited new edition of this classic work has finally appeared (the first edition was published by the senior author as Mineralogische Tabellen in 1941, with subsequent editions in 1949, with subsequent editions in 1957, with subsequent editions in 1966, with subsequent editions in 1970, with subsequent editions in 1977, with subsequent editions in 1978, and 1982). One must congratulate Hugo Strunz on the authorship of this work over some 60 years. He has been fortunate in obtaining another distinguished mineralogist, Ernest Nickel, as co-author of this, the first edition in English. This edition is a complete revision of the fifth (1970) edition, since subsequent editions were essentially reprints of that work. Compared to the fifth edition, this edition more than …

A sample of five tektites (australites) from the northern Tanami Desert of the Northern Territory contributes to the definition of the strewn field in northern Australia. Two tektites are of the HMg (high magnesium) type, while three are of ' normal' composition. The sample lies on the projected depositional streak of HCa (high calcium) australites, but the absence of any specimens of HCa composition suggests that, unlike the HMg and ' normal' depositional areas, the HCa area does not extend into the northern part of the continent.

Capgaronnite, ideally HgAg(Cl,Br,I)S, is a new mineral from the Cap-Garonne copper-lead mine, Var, France. The mineral is orthorhombic, space group P2(1)2(1)2, with a = 6.803(8), b = 12.87(1), c = 4.528(7), and Z = 4. The composition and crystal structure of capgaronnite are related to those of perroudite [5HgS.4Ag(Cl,Br,I)] previously reported from the Cap-Garonne locality. Like perroudite, capgaronnite probably crystallized following decomposition of Hg- and Ag-bearing tennantite by halide-bearing solutions of marine origin. Capgaronnite is pleochroic in very thin splinters, with alpha = dark brown and gamma = gray to clear purple. The optical orientation is alpha = c, beta = b, and gamma = a. Indices of refraction measured by reflectance measurements on oriented crystals in polished section were alpha is similar to 2.2, gamma is similar to 2.3; beta could not be measured because the crystals are very thin parallel to beta = b. A preliminary solution of the capgaronnite atomic arrangement (R = 0.17) was obtained from X-ray film intensities. In capgaronnite, (010) layers of face-shared Hg octahedra built around chains of continuous -S-Hg-S- bonds are joined by cross-linked, paired groups of Ag tetrahedra.

Chemical analyses and petrographic data are given for 11 samples of granitoid rocks, ranging in composition from tonalites through granodiorites to adamellites; rare-earth element CREE) concentrations and other minor and trace elements have been determined in five of them.
