(2010) recently interpreted sector-boundary zoned chiastolite as syntectonic on the basis of the presence of curved type 2 quartz inclusions (intergrowths).
The last two minerals are associated with opaque mineral intergrowths, and their cleavage is also observed with some spheroidal minerals, which possibly correspond to chlorite.
It occurs through most of the sample as an intergrowth with dolomite (15-75%) rhomb sections (Figures 4a-b, 8d-f).
Although the main objective of these indices is the discrimination between different types of mineral intergrowths, the assessment of their mineralurgical meaning is also important.
Mason's original conclusions that there was complete miscibility in the [Fe.sub.3][O.sub.4]-[ZnFe.sub.2][O.sub.4] system (Mason, 1947) were subsequently revised by the analysis of magnetite-franklinite-pyrophanite intergrowths from Sterling Hill, New Jersey (Valentino et al., 1990).
Perthitic and myrmekitic intergrowths are observed in few sections.
Granophyric (more wormy) to graphic (more cuneiform) intergrowths between feldspar and quartz are evident in three samples (DDH 79-6-174.3, DDH 81-26-63.4, and DDH83-1-37.5; Fig.
Un the other hand, thin sections from the Bernkopf locality show a curious texture in some places--fingerprint hercynite + quartz symplectitic intergrowths as shown in Figs.
NIST research on [Li.sub.1+x-y][Nb.sub.1-x-3y][Ti.sub.x+4y][O.sub.3] ceramics has demonstrated that what actually forms is not a solid solution but rather a homologous series of distinct compounds which feature intergrowths of [LiNbO.sub.3]-type blocks and corundum-type layers.
