  • Kennedyite, a New Mineral of the Pseudobrookite Series
    676 Kennedyite, a new mineral of the pseudobrookite series. By O. VON KNORRING, Ph.D., and K. G. Cox, Ph.D. Research Institute of African Geology, University of Leeds. [Read 26 January 1961.] Summary. A new mineral with the approximate composition of F%MgTiaOxoand isostructural with pseudobrookite F%Ti2010has been observed in an olivine-augite- alkali-feldsparrock of the Karroo succession from the Mateke Hills area in south- eastern Southern Rhodesia. Chemical analysis and indexed X-ray powder data (a 9"77, b 9-95, c 3"73 ~.) of the mineral are given, and the name kennedyite is pro- posed. The name karrooite is proposed for the artificial product MgTi~O5. HE Mateke Hills area lies in the south-eastern part of Southern T Rhodesia and is characterized by several ring-complexes of late- Karroo age, which are emplaced in an extensive trough of Karroo vol- canics with generally thin basal sediments. The Karroo rocks rest un- conformably on the paragneisses of the Limpopo valley. The lower part of the Karroo volcanic succession consists mainly of olivine-rich rocks. These are in part extrusive and may be termed in general limburgites, and in part intrusive as sills, dykes, and plugs. The intrusive rocks are fine- to medium-grained and vary in composition from olivine-dolerites to pieritic and shonkinitic types. The specimens containing the new mineral were collected from what is believed to be an extensive sill at the base of the volcanic succession immediately overlying the Cave Sandstone. Petrographic description. Under the microscope the rock (table I, anal. 1) consists predominantly of broken and abraded olivine pheno- crysts from 1 to 5 mm.

  • Download PDF About Minerals Sorted by Mineral Name
    MINERALS SORTED BY NAME Here is an alphabetical list of minerals discussed on this site. More information on and photographs of these minerals in Kentucky is available in the book “Rocks and Minerals of Kentucky” (Anderson, 1994). APATITE Crystal system: hexagonal. Fracture: conchoidal. Color: red, brown, white. Hardness: 5.0. Luster: opaque or semitransparent. Specific gravity: 3.1. Apatite, also called cellophane, occurs in peridotites in eastern and western Kentucky. A microcrystalline variety of collophane found in northern Woodford County is dark reddish brown, porous, and occurs in phosphatic beds, lenses, and nodules in the Tanglewood Member of the Lexington Limestone. Some fossils in the Tanglewood Member are coated with phosphate. Beds are generally very thin, but occasionally several feet thick. The Woodford County phosphate beds were mined during the early 1900s near Wallace, Ky. BARITE Crystal system: orthorhombic. Cleavage: often in groups of platy or tabular crystals. Color: usually white, but may be light shades of blue, brown, yellow, or red. Hardness: 3.0 to 3.5. Streak: white. Luster: vitreous to pearly. Specific gravity: 4.5. Tenacity: brittle. Uses: in heavy muds in oil-well drilling, to increase brilliance in the glass-making industry, as filler for paper, cosmetics, textiles, linoleum, rubber goods, paints. Barite generally occurs in a white massive variety (often appearing earthy when weathered), although some clear to bluish, bladed barite crystals have been observed in several vein deposits in central Kentucky, and commonly occurs as a solid solution series with celestite where barium and strontium can substitute for each other. Various nodular zones have been observed in Silurian–Devonian rocks in east-central Kentucky.

  • Get Reactive in System 96!
    Get Reactive in System 96! Uroboros has created two unique glass formulas for System 96 that are designed to create an interface color, or a reac on, when melted against certain other colors. This occurs when ions from the two adjacent glasses migrate and mingle when the gl asses become hot and ß uid. Given the right glass chemistry, the comingled ions form a very thin colored line, or reac on. Since our formulas react to create a no ceably reddish hue we named them Red Reac ves: as in Red Reac ve Transparent, and Red Reac ve Opal. The primary ingredient needed in a glass to generate a reac on color with our Reac ve glass is Copper. Copper is present in many blue and blue-green glass colors, but in some cases in too low a concentra on to create a no ceable reac on. For simplicity, all System 96 colors have been graded for their poten al to react into three categories: Strong, Medium, and Mild. See them all listed in the chart on the back of this page. You will Þ nd that the intensity of the reac on color will get stronger with longer, ho er, or repeat Þ rings. This is because the copper ions have more me to mingle with their friendly reac ve partners in the adjacent glass. The chart rankings are based on a typical single Þ ring cycle. You could get a Medium reac on from a color graded as Mild by Þ ring it ho er, or Þ ring mul ple mes.
