Berthierine has been identified by the lack of 14A basalreflections on X-ray powderdiffractionpattems, by its composition (electron-microprobedata), and by transmissionelectron microscopy (TEM). Peoogaphic and scanning eiectronmicroscopic (SEM) studiesreveal different types of berthierineocculrences, including interlayerswithin and rims on deformedchlorite, intergrowthswith muscoviteand halloysite,and discretecoarse grains.

Study of the Modifications of Manganese Dioxide by Howard F
U. S. Department of Commerce Research Paper RP1941 National Bureau of Standards Volume 41, December 1948 Part of the Journal of -Research of the National Bureau of Standards Study of the Modifications of Manganese Dioxide By Howard F. McMurdie and Esther Golovato Past work on the modifications of manganese dioxide of interest in dry-cell manufacture is reviewed. New X-ray data, at both room and elevated temperatures, combined with differential heating curves lead to the conclusion that five types of manganese dioxide exist: (1) well-crystallized pyrolusite; (2) gamma manganese dioxide, a poorly crystallized pyrolu- site; (3) ramsdellite; (4) cryptomelane, a form containing essential potassium or sodium; and (5) delta manganese dioxide, believed to be a poorly crystallized cryptomelane. The high-temperature X-ray diffraction data indicated the phase changes that cause the heating- curve effects. A new crystal form of manganosic oxide (M113O4), stable above 1,170° C, w^s found to be cubic of spinel structure. Fineness determinations by both the nitrogen adsorp- tion and the X-ray line broadening methods were made on selected samples. I. Introduction this equipment a flat specimen is used, and no During the years 1940-46 there was increased special techniques were employed to prevent pre- research on (Jry cells. This was stimulated by ferred orientation. It is realized that in a few increased demand for the cells as well as new uses cases this may have resulted in relative intensities for them, combined with certain shortages of raw that differ from those in other reports. This materials. This work disclosed among other equipment in its commercial form is not capable things that manganese dioxide is not a simple of recording the diffraction effects at angles greater compound with constant properties, and that its than 45° 0; thus; the back reflection lines are value as a depolarizer depends on properties other missed. -

Bouazzerite is associated with quartz, chalcopyrite, native gold, erythrite, talmessite/roselite-beta, Cr-bearing yukonite, alumopharmacosiderite, powellite, and a blue-green earthy copper arsenate related to geminite. The mineral results from the weathering of a Va- riscan hydrothermal As-Co-Ni-Ag-Au vein. The Bou Azzer mine and the similarly named district have produced many outstanding mineral specimens, including the world’s best erythrite and roselite. Bouazzerite forms monoclinic prismatic {021} crystals up to 0.5 mm in length. It has a pale 3 apple green color, a colorless streak, and is translucent with adamantine luster. dcalc is 2.81(2) g/cm (from X-ray structure refi nement).
