    Hydroxyl Stretching Frequencies in the Infrared Spectra of Anthophyllites and Gedrites (1970)
    [s.l.] : Nature Publishing Group
    Nature 226 (1970), S. 73-75 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Site population estimates for amphiboles by the infrared technique are based on stretching frequencies of hydroxyl groups in the O(3) position coordinated to cations in the one M(3) and two M(1) positions. The four combinations of Mg2+ and Fe2+ in these positions in cummingtonite give rise to four ...

    Determination of the Cation Distribution in the Orthopyroxene Series by the Mossbauer Effect (1967)
    [s.l.] : Nature Publishing Group
    Nature 213 (1967), S. 1221-1223 
    Details

    Notes: [Auszug] We have used Mossbauer spectroscopy to estimate site populations in a suite of orthopyroxenes derived from regionally metamorphosed rocks11. Measurements were made at room temperature9'12 on five orthopyroxenes of the enstatite-orthoferrosilite series with 14-5-85-9 cation per cent iron (II), and a ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The red colour of the surface of Mars has long been attributed to Fe3+-bearing minerals in the regolith, implying that oxidizing conditions have prevailed. However, the apparent enrichment of iron in martian regolith, its mineralogy and the nature of the unweathered parent rocks remain poorly ...

    Notes: [Auszug] THE publication of a new edition of a very successful, widely acclaimed reference text some 15-20 years after the previous edition always arouses interest and curiosity. Have the authors, now well into or beyond their prime, kept abreast of rapid developments in their field? Have they been able to ...

    Notes: [Auszug] BURNS REPLIES-When it was suggested that feroxyhyte might occur on the surface of Mars1, I was well aware2'3 of the claimed distinction between the ferromagnetic phase 5-FeOOH and the terrestrial mineral feroxyhyte (d'-FeOOH). Towe points out that in their original descriptions of feroxyhyte, ...

    Notes: [Auszug] Synthetic (d-FeOOH is formed as a deep-brown precipitate during the oxidation of Fe(OH)2 in partially deoxygenated, slightly alkaline solutions7,8. It is generally poorly crystalline and may contain up to 3wt % excess H2O (ref. 7). Significantly, (d-FeOOH differs from other FeOOH polymorphs by ...

    Notes: [Auszug] MANGANESE nodules are intriguing marine deposits because contained in the very finegrained matrix are accumulations of the strategic metals cobalt, nickel, copper, manganese and molybdenum. Understanding how these deep-sea ferro-manganese oxide concretions formed, and the processes by which the ...

    Notes: [Auszug] Observations of the interiors of manganese nodules under the microscope5, together with electron microprobe analyses6"8, reveal the intimate associations and oscillatory intergrowths of the manganese- and iron-bearing minerals. Most nodules have formed about a nucleus consisting of pumice, altered ...

    Notes: [Auszug] One type of manganese mineralisation is related to calc-alkaline magmatism. Reports on porphyry copper deposits and numerous manganese ore deposits have revealed that the two mineralisations seem to be contemporaneous within calc-alkaline terrains11. Porphyry copper deposits consistently occur over ...
