The correlation between lithium and magnesium in trioctahedral micas: Improved equations for Li2O estimation from MgO data
Autor: G. Tischendorf, H. J. Forster, B. Gottesmann
Publikováno v: Mineralogical Magazine. 63:57-74
A major disadvantage of the electron microprobe is its inability to determine Li, which may make up an essential component in micaceous minerals. Correct classification of micas and proper calculation of their formulae require alternative methods. On

Andalusite occurs as an accessory mineral in many types of peraluminous felsic igneous rocks, including rhyolites, aplites, granites, pegmatites, and anatectic migmatites. Some published stability curves for And = Sil and the water-saturated granite

Chemical and boron-isotope variations in tourmalines from an S-type granite and its source rocks: the Erongo granite and tourmalinites in the Damara Belt, Namibia
Autor: Michael Wiedenbeck, Robert B. Trumbull, Marc-Sebastian Krienitz, B. Gottesmann
Publikováno v: Contributions to Mineralogy and Petrology
Tourmaline is widespread in metapelites and pegmatites from the Neoproterozoic Damara Belt, which form the basement and potential source rocks of the Cretaceous Erongo granite. This study traces the B-isotope variations in tourmalines from the baseme

True and brittle micas: composition and solid-solution series
Autor: Milan Rieder, G. Tischendorf, H. J. Forster, B. Gottesmann
Publikováno v: Mineralogical Magazine
Micas incorporate a wide variety of elements in their crystal structures. Elements occurring in significant concentrations in micas include: Si, IVAl, IVFe3+, B and Be in the tetrahedral sheet; Ti, VIAl, VIFe3+, Mn3+, Cr, V, Fe2+, Mn2+, Mg and Li in

A new graphical presentation and subdivision of potassium micas
Autor: C. V. Guidotti, B. Gottesmann, G. Tischendorf, H. J. Forster, Milan Rieder
A system based on variation of the octahedrally coordinated cations is proposed for graphical presentation and subdivision of tri- and dioctahedral K micas, which makes use of elemental differences (in a.p.f.u.): (Mg – Li) [= mgli] and (Fetot + Mn
