1
Disilicates and Ring Silicates
The upper stability limit of gehlenite was determined in the presence of excess
H20 by Huckenholz and Yoder (1974) at up to l0kbar (Fig. 139). Neither the
quench product nor the primary gehlenite was hydrated, i.e. no bicchulite, ...
William Alexander Deer, Robert Andrew Howie, J. Zussman, 1997
The contents of the latter component in the liquid phase were therefore probably
substantially lower than 5%. 2.4.3 Phases structurally related to gehlenite The
phases C3A2M, C7A5M and 'Q' are structurally related to each other and to C5A3
...

Structure and Performance of Cements, Second Edition
The melilite phase in CAC is normally closer in composition to the gehlenite (
C2AS) end of the gehlenite-åkermanite solid-solution series and, to a first
approximation, can be regarded as gehlenite. The gehlenite hydrates slowly to
form ...

Geopolymer Chemistry and Applications
The spectrum is similar to those of synthetic geopolymer cements. The chemical
reaction yields an alumino-silicate structure with a major resonance at -86 ppm
suggesting a structure of the Si(Q3.1OH) (hydrated gehlenite) and Si(Q4) types, ...
Rodney Grapes. Muck The contact zone of a large olivine dolerite dyke intruding
limestone on the Island of Muck, Scotland, is documented by Tilley (1947) and
characterised by gehlenite- bearing sanidinite facies assemblages of: a.

Rock-forming Minerals in Thin Section
Ákermanite Ca2Mg[Si2OY] Gehlenite Ca,Al[Al,Si)2OY] General features: there is
isomorphic solid solution between the two endmembers. ákermanite and
gehlenite. Occurrence restricted to silica undersaturated magmas. Melilite is not a

Hans Pichler, Cornelia Schmitt-Riegraf, 1997

Cleaner Combustion and Sustainable World
In the 1,050 C ash sample, the anhydrite reduced with the increase of anorthite,
and gehlenite apparently existed in the sample. In addition, attention should also
be paid to the changes of other parts of phases in all heating samples. Quartz ...
Haiying Qi, Bo Zhao, 2012

Physics and Chemistry of Circumstellar Dust Shells
At lower temperature, the Ca-Al compound gehlenite with composition
Ca2Al2SiO7 has a higher pseudoactivity than corundum. Because the Ca
abundance is less than the Al abundance, it is not possible to condense all the Al
into gehlenite.
Hans-Peter Gail, Erwin Sedlmayr, 2013

The constitution of the silicates
Two additional species, meliliteand gehlenite, which, like vesuvianite, are also
tetragonal, may perhaps be best considered at this stage of the discussion. For
melilite, the analyses are somewhat discordant; but on the whole they agree best
...
Frank Wigglesworth Clarke, 1896

Kinetic Theory in the Earth Sciences
If this growth is completely controlled by diffusion (see growth chapter), then all
the reaction is taking place at the two interfaces in the figure, i.e., at the calcite-
wollastonite + gehlenite end (C-WG) and at the wollastonite + gehlenite-anorthite
