The structure and spectral properties of two copper bearing 14 xocomecatlite and tlapallite are compared with an iron bearing rodalquilarite mineral. 15 Two prominent bands observed at 9855 and 9015 cm-1 are 16 2 2 2 2 2+ 17 assigned to B1g → B2g and B1g → A1g transitions of Cu ion in xocomecatlite. 18 19 The cause of spectral distortion is the result of many cations of Ca, Pb, Cu and Zn the 20 in tlapallite mineral structure. Rodalquilarite is characterised by ferric ion absorption 21 in the range 12300-8800 cm-1. 22 Three water vibrational overtones are observed in xocomecatlite at 7140, 7075 23 and 6935 cm-1 where as in tlapallite bands are shifted to low wavenumbers at 7135, 24 7080 and 6830 cm-1. The complexity of rodalquilarite spectrum increases with more 25 number of overlapping bands in the near-infrared. -

Bull Mineral Petrolog 26(2): 250-258. ISSN 2570-7337 Abstract Two rare copper diselenides, kruťaite and petříčekite, were found in two museum samples of vein fillings from the uranium mine Slavkovice, western Moravia (Czech Republic). Kruťaite occurs as small isometric isolated euhedral to subhedral zoned crystals enclosed and partly replaced by umangite. Petříčekite forms small elongated or isometric inclusions enclosed by kruťaite and other Cu-selenides. Optical data, Raman spectra and chemical composition of both phases are specified in this paper. Kruťaite contains elevated contents of Co (up to 0.15apfu ) and Ni (up to 0.09 apfu), whereas petříčekite is Ni-Co free and enriched in Fe (up to 0.25 apfu). Both phases seem to be the oldest selenides in the given assemblage, and are associated with umangite, athabascaite, eskebornite, klockmannite, bukovite, urani- nite, chalcopyrite, calcite and hematite. The studied ore assemblage originated at temperature not exceeding ca. -

These uranium deposits are hosted by faults that are mostly developed in low- to high-grade metamorphic rocks of the basement of the Bohemian Massif. Textural features and the chemical composition of uraninite, coffinite and ningyoite were studied using an electron microprobe. Collomorphic uraninite was the only primary uranium mineral in all deposits studied. The uraninites contained variable and elevated concentrations of PbO (1.5 wt %–5.4 wt %), CaO (0.7 wt %–8.3 wt %), and SiO2 (up to 10.0 wt %), whereas the contents of Th, Zr, REE and Y were usually below the detection limits of the electron microprobe. -

The Minerals and Rocks of the Earth 5A: the Minerals- Special Mineralogy
Lesson 5 cont’d: The Minerals and Rocks of the Earth 5a: The minerals- special mineralogy A. M. C. Şengör In the previous lectures concerning the materials of the earth, we studied the most important silicates. We did so, because they make up more than 80% of our planet. We said, if we know them, we know much about our planet. However, on the surface or near-surface areas of the earth 75% is covered by sedimentary rocks, almost 1/3 of which are not silicates. These are the carbonate rocks such as limestones, dolomites (Americans call them dolostones, which is inappropriate, because dolomite is the name of a person {Dolomieu}, after which the mineral dolomite, the rock dolomite and the Dolomite Mountains in Italy have been named; it is like calling the Dolomite Mountains Dolo Mountains!). Another important category of rocks, including parts of the carbonates, are the evaporites including halides and sulfates. So we need to look at the minerals forming these rocks too. Some of the iron oxides are important, because they are magnetic and impart magnetic properties on rocks. Some hydroxides are important weathering products. This final part of Lesson 5 will be devoted to a description of the most important of the carbonate, sulfate, halide and the iron oxide minerals, although they play a very little rôle in the total earth volume. Despite that, they play a critical rôle on the surface of the earth and some of them are also major climate controllers. The carbonate minerals are those containing the carbonate ion -2 CO3 The are divided into the following classes: 1. -

Revision 2 of Ms. 5419 Time’s Arrow in the Trees of Life and Minerals Peter J. Heaney1,* 1Dept. of Geosciences, Penn State University, University Park, PA 16802 *To whom correspondence should be addressed: [email protected] Page 1 Revision 2 of Ms. 5419 1 ABSTRACT 2 Charles Darwin analogized the diversification of species to a Tree of Life. 3 This metaphor aligns precisely with the taxonomic system that Linnaeus developed 4 a century earlier to classify living species, because an underlying mechanism – 5 natural selection – has driven the evolution of new organisms over vast timescales. 6 On the other hand, the efforts of Linnaeus to extend his “universal” organizing 7 system to minerals has been regarded as an epistemological misfire that was 8 properly abandoned by the late nineteenth century. 9 The mineral taxonomies proposed in the wake of Linnaeus can be 10 distinguished by their focus on external character (Werner), crystallography (Haüy), 11 or chemistry (Berzelius). This article appraises the competition among these 12 systems and posits that the chemistry-based Berzelian taxonomy, as embedded 13 within the widely adopted system of James Dwight Dana, ultimately triumphed 14 because it reflects Earth’s episodic but persistent progression with respect to 15 chemical differentiation. In this context, Hazen et al.’s (2008) pioneering work in 16 mineral evolution reveals that even the temporal character of the phylogenetic Tree 17 of Life is rooted within a Danan framework for ordering minerals. 18 19 Page 1 Revision 2 of Ms. 5419 20 INTRODUCTION 21 In an essay dedicated to the evolutionary biologist Ernst Mayr, Stephen Jay 22 Gould (2000) expresses his indignation at the sheer luckiness of Carolus Linnaeus 23 (1707-1778; Fig. -
