  • Gaspéite-Magnesite Solid Solutions and Their Significance

    Gaspéite-Magnesite Solid Solutions and Their Significance

    78 Advances in Regolith GASPÉITE-MAGNESITE SOLID SOLUTIONS AND THEIR SIGNIFICANCE Meagan E. Clissold, Peter Leverett & Peter A. Williams School of Science, Food and Horticulture, University of Western Sydney, Locked Bag 1797, Penrith South DC NSW 1797 It is a surprising fact that, despite the increasing number of secondary minerals of Ni(II) recognized from oxidized base metal deposits (Anthony et al. 2003), the supergene chemistry responsible for their formation remains poorly understood. An understanding of this chemistry would be desirable in view of its importance with respect to geochemical exploration for the element, its behaviour in the regolith and the potential development of commercially exploitable secondary nickel resources. Of the secondary nickel minerals known, gaspéite, NiCO3, is perhaps the most common and has been observed in a number of Western Australian deposits. Notable among these is the 132 pit at Widgiemooltha, near Kambalda, WA (Nickel et al.1994). The supergene profile of the 132 pit consists of 5 zones: oxide, carbonate, violarite-pyrite, transition and primary zone. The carbonate zone is 3-12 m below surface and is characterized by the occurrence of a number of flat-lying to sub-horizontal veins of gaspéite that cut across altered wall rock comprising tremolite and goethite. These veins extend from what was a large sulfide body across the matrix layer. Single gaspéite veins have a size of 5 x 5 x 0.05 m on average and may occur in masses of up to 10 x 10 x 1 m; they are typically massive to either granular or fibrous. From the lower part of the carbonate zone upwards there is a progressive decrease in the amount of gaspéite and other carbonate minerals, and their respective nickel contents.

  • IMA Master List

    IMA Master List

    The New IMA List of Minerals – A Work in Progress – Update: February 2013 In the following pages of this document a comprehensive list of all valid mineral species is presented. The list is distributed (for terms and conditions see below) via the web site of the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association, which is the organization in charge for approval of new minerals, and more in general for all issues related to the status of mineral species. The list, which will be updated on a regular basis, is intended as the primary and official source on minerals. Explanation of column headings: Name: it is the presently accepted mineral name (and in the table, minerals are sorted by name). Chemical formula: it is the CNMNC-approved formula. IMA status: A = approved (it applies to minerals approved after the establishment of the IMA in 1958); G = grandfathered (it applies to minerals discovered before the birth of IMA, and generally considered as valid species); Rd = redefined (it applies to existing minerals which were redefined during the IMA era); Rn = renamed (it applies to existing minerals which were renamed during the IMA era); Q = questionable (it applies to poorly characterized minerals, whose validity could be doubtful). IMA No. / Year: for approved minerals the IMA No. is given: it has the form XXXX-YYY, where XXXX is the year and YYY a sequential number; for grandfathered minerals the year of the original description is given. In some cases, typically for Rd and Rn minerals, the year may be followed by s.p.

The structure has two symmetry independent Mn sites. The Mn1 site is seven coordinated by O and hosts, in addition to Mn2+, up to 20% Ca, whereas Mn2 has octahedral coordina- tion and is strongly selective for Mn2+. In the simplified formula, three smaller octahedral M sites are occupied by Al. However, M1 also accepts significant amounts of divalent cations, such as Cu, Mg, Fe, and Mn, whereas M2 is occupied exclusively by Al. The unit-cell parameters of sursassite are a = 8.698–8.728, b = 5.789–5.807, c = 9.778–9.812 Å, β = 108.879–109.060°, V = 465.7–470.0 Å3, the space group is P21/m.

    STRONG AND WEAK INTERLAYER INTERACTIONS OF TWO-DIMENSIONAL MATERIALS AND THEIR ASSEMBLIES Tyler William Farnsworth A dissertation submitted to the faculty at the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Chemistry. Chapel Hill 2018 Approved by: Scott C. Warren James F. Cahoon Wei You Joanna M. Atkin Matthew K. Brennaman © 2018 Tyler William Farnsworth ALL RIGHTS RESERVED ii ABSTRACT Tyler William Farnsworth: Strong and weak interlayer interactions of two-dimensional materials and their assemblies (Under the direction of Scott C. Warren) The ability to control the properties of a macroscopic material through systematic modification of its component parts is a central theme in materials science. This concept is exemplified by the assembly of quantum dots into 3D solids, but the application of similar design principles to other quantum-confined systems, namely 2D materials, remains largely unexplored. Here I demonstrate that solution-processed 2D semiconductors retain their quantum-confined properties even when assembled into electrically conductive, thick films. Structural investigations show how this behavior is caused by turbostratic disorder and interlayer adsorbates, which weaken interlayer interactions and allow access to a quantum- confined but electronically coupled state. I generalize these findings to use a variety of 2D building blocks to create electrically conductive 3D solids with virtually any band gap. I next introduce a strategy for discovering new 2D materials. Previous efforts to identify novel 2D materials were limited to van der Waals layered materials, but I demonstrate that layered crystals with strong interlayer interactions can be exfoliated into few-layer or monolayer materials.
