    www.degruyter.com/view/j/ammin.2008.93.issue-1/am.2008.2666/am.2008.2666.xml The crystal structure of direnzoite, a new natural zeolite found in the cavities of a xenolitic rock from the Massif Central (France) is reported. Apparently, direnzoite was formed throughout a process of hydrothermal crystallization within the vugs of a highly porphyric basalt.

  • Dufrénite: Mineral information, data and localities.

    www.mindat.org/min-1323.html A secondary mineral occurring with limonite in gossan of veins and in iron ore deposits. See also natrodufrénite which appears to be much more common than presently thought (Henry Barwood, unpubl. results). A (formally) vacancy- and Mn 2+-dominant member was reported by Sejkora et al. (2006). Note: dufrénite is the correct spelling, not dufrenite (Burke, 2008).

    www.sciencedirect.com/science/article/pii/S0167299108802492 Direnzoite [1] is the natural counterpart of synthetic ECR-1 whose structure model was proposed on the basis of HRTEM and structure solution of the isotype gallo-silicate TNU-7 [2] and confirmed later by Rietveld structure refinement [3]. Both structures were solved and refined using the powder methods because of the inability to pick crystals ...

    link.springer.com/article/10.1134/S0020168516080112 The three-dimensional geometric analysis carried out in this study has made it possible to clearly outline the homogeneity regions of solid solutions rich in magnesium and potassium oxides. Common elements in the structures of the zeolites (offretite, direnzoite, and ferrierite-Mg) have been identified and the factors responsible for the ...
