ANNITE STABILITY REVISED. 1. HYDROGEN-SENSOR DATA FOR THE REACTION ANNITE = SANIDINE + MAGNETITE + H2

Dachs E. (1994)

In P - T - logfO2 space, the stability of annite (ideally KFe 32+(OH)2AlSi3O10) at high fO2 (low fH2) is limited by the reaction: annite = sanidine + magnetite + H2. Using the hydrogen-sensor technique, the equilibrium fH2 ...
COMPREHENSIVE CHEMICAL ANALYSES OF NATURAL CORDIERITES: IMPLICATIONS FOR EXCHANGE MECHANISMS

Bertoldi C.; Garbe-Schönberg D.; Dachs E.; Proyer A.; Behrens H. (2004)

Cordierite samples from pegmatites and metamorphic rocks have been analysed for major [electron microprobe analysis (EMPA)] and trace elements [inductively coupled plasma mass spectrometry (ICP-MS), secondary ion mass ...
HEAT CAPACITIES OF TSCHERMAK SUBSTITUTED FE-BIOTITE

Benisek A.; Dachs E.; Cemic L. (1999)

Six members of the annite-siderophyllite join were synthesized in a three step process - crystallization of biotite from gels, decomposition of the fine-grained biotite under oxidizing conditions and resynthesis of Fe-Al ...
THE HEAT CAPACITY OF TWO NATURAL CHLORITE GROUP MINERALS DERIVED FROM DIFFERENTIAL SCANNING CALORIMETRY

Bertoldi C.; Benisek A.; Cemic L.; Dachs E. (2001)

The heat capacity of natural chamosite (XFe=0.889) and clinochlore (XFe=0.116) were measured by differential scanning calorimetry (DSC). The samples were characterised by X-ray diffraction, microprobe analysis and Mössbauer ...
