Mapping singularities — a technique to identify potential Cu mineral deposits using sediment geochemical data, an example for Tibet, west China
Mineralogical Magazine - Tập 72 Số 1 - Trang 531-534 - 2008
Renguang Zuo, Qiuming Cheng
AbstractGeochemical anomalies can be used in mineral resource exploration. We demonstrate a technique for mapping anomalies. The Gangdese mineral district in Tibet, west China was chosen as a study area for identifying geochemical anomalies and predicting Cu mineral resources using sediment geochemical data. The results show that the anomalies are associated both w...... hiện toàn bộ
The optical constants of natural and artificial cuprite by an ellipsometric method
Mineralogical Magazine - Tập 42 Số 324 - Trang 505-508 - 1978
E.F.I. Roberts, P. Rastall
SummaryEllipsometric measurements in the spectral range 250–850 nm have been made on polished single crystals of natural cuprite from Namibia and of artificial cuprite grown by a total-oxidation method from pure copper. Derived values of the refractive indices, absorption coefficients, normal reflectances, and the complex dielectric constants for the two materials ...... hiện toàn bộ
Multispectral imaging of ore minerals in optical microscopy
Mineralogical Magazine - Tập 68 Số 2 - Trang 323-333 - 2004
Éric Pirard
AbstractMultispectral imaging of ore minerals under the microscope is a logical extension of quantitative colour analysis and microspectrophotometric analysis of minerals. This paper describes, step by step, how the proper calibration of a scientific video camera can be performed in order to obtain precise reflectance measurements at each pixel within the field of ...... hiện toàn bộ
TheREE-and HFSE-bearing phases in the Itatiaia alkaline complex (Brazil) and geochemical evolution of feldspar-rich felsic melts
Mineralogical Magazine - Tập 81 Số 2 - Trang 217-250 - 2017
Leone Melluso, Vincenza Guarino, Michele Lustrino, Vincenzo Morra, Roberto dè Gennaro
AbstractThe Late Cretaceous Itatiaia complex is made up of nepheline syenite grading to peralkaline varieties, quartz syenite and granite, emplaced in the metamorphic rocks of the Serra do Mar, SE Brazil. The nepheline syenites are characterized by assemblages with alkali feldspar, nepheline, Fe-Ti oxides, clinopyroxene, amphibole, apatite and titanite, while the p...... hiện toàn bộ
A general equation for estimating Fe3+ concentrations in ferromagnesian silicates and oxides from microprobe analyses, using stoichiometric criteria
Mineralogical Magazine - Tập 51 Số 361 - Trang 431-435 - 1987
G. T. R. Droop
AbstractA simple general equation is presented for estimating the Fe3+ concentrations in ferromagnesian oxide and silicate minerals from microprobe analyses. The equation has been derived using stoichiometric criteria assuming that iron is the only element present with variable valency and that oxygen is the only anion. In general, the number o...... hiện toàn bộ

Chemistry of chromian spinel in volcanic rocks as a potential guide to magma chemistry
Mineralogical Magazine - Tập 56 Số 383 - Trang 173-184 - 1992
Shoji Arai
AbstractChromian spinel in volcanic rocks is a potential discriminant for magma chemistry. The TiO2 content of spinel, compared at similar Fe3+/(Cr + Al + Fe3+) ratios, can distinguish island arc basalts from intraplate basalts. MORB spinels are low in this ratio and are intermediate for the TiO... hiện toàn bộ
P-Tconditions during emplacement, and D2 regional metamorphism, of the Ben Vuirich Granite, Perthshire, Scotland
Mineralogical Magazine - Tập 64 Số 4 - Trang 737-753 - 2000
Y. Ahmed-Said, Peter Tanner
AbstractThe 590±2 Ma Ben Vuirich Granite was intruded into late Proterozoic Dalradian rocks prior to the Grampian orogeny, during which it was affected by upper amphibolite facies regional metamorphism. Spotted cordierite and andalusite (chiastolite) hornfelses at the granite margin were altered to kyanite-and garnet-bearing assemblages during regional metamorphism...... hiện toàn bộ
Raman and infrared spectroscopic study of the vivianite-group phosphates vivianite, baricite and bobierrite
Mineralogical Magazine - Tập 66 Số 6 - Trang 1063-1073 - 2002
R. L. Frost, Wayde N. Martens, Pete A. Williams, J. Theo Kloprogge
AbstractThe molecular structure of the three vivianite-structure, compositionally related phosphate minerals vivianite, baricite and bobierrite of formula M32+(PO4)2.8H2O where M is Fe or Mg, has been assessed using a combination of Ra...... hiện toàn bộ
