pyroxenoid nella seguente selezione bibliografica. Libri associati con
pyroxenoid e piccoli estratti per contestualizzare il loro uso nella letteratura.
1
Structure and Bonding in crystals
Phase transitions among these structures are of three types: (a) changes in
silicate chain repeat distance leading to transitions between pyroxene and
pyroxenoid structure; (b) changes in chain-bending leading to symmetry changes
(ortho ...

High Pressure Research in Mineral Physics
The enthalpies of transition among pyroxene and pyroxenoid polymorphs are
uniformly small. The pyroxenoid (or pyroxene) to garnet transition has a AH° of
less than 10 k J mof' in magnitude for CaGeCh and CdGeOi, 36 kJ mof' in
MnSiCh ...

Abstracts for 1968: Abstracts of papers submitted for seven ...
In some metamorphic manganese deposits, rhodochrosite (MnCOa) and quartz
reacted to MnSi03 component in a pyroxenoid mineral; rhodochrosite and
pyroxenoid reacted to tephroite (MnZSiOr); and carbonate decomposed to
manganosite ...

Silicate Structures and dispersion system
Another very characteristic example of combined structural and optical (i.e.,
absorption-spectroscopic investigations for manganese-containing minerals with
pyroxenoid-type (Fig. A.49) infinite metasilicate chains) is given by P. G.
Manning356 ...
ketten (Prewitt and Peacor, 1964). Although a general correlation between
average metal cation size and silicate chain-repeat length was noted by Liebau (
1962), the compositional limits of the various pyroxenoid structures remain
largely ...

Proceedings of the Apollo 11 Lunar Science Conference
The range of zoning in the pyroxenoid of 10058 varies from grain to grain but it
seems to extend from compositions near Ca22Mg20Fe5g to Ca12Mg2Fe86.
More lime- rich final compositions near Ca20Mg2Fe78 are encountered in other
...
It is a pyroxenoid mineral, with a crystal structure similar to that of the pyroxene
group of minerals, which consist of single chains of SiO4 tetrahedra; however, in
a pyroxenoid, the SiO4 chains are distorted (Mamedov and Belov, 1956).
