Continental Reactivation and Reworking
These phyllonites usually lie close to or within zones of cataclastically deformed
psammite in which feldspars display varying degrees of retrograde sericitisation.
Overall, the style of deformation at Dochanassie is comparable to that at Loch ...

Introduction to Metamorphic Textures and Microstructures
Sericitisation. The alteration of K-feldspar, plagioclase, Al2SiOs polymorphs,
staurolite and cordierite to fine-grained aggregates of white mica (termed 'sericite'
) is a common feature of retrogressed quartzofeldspathic rocks and metapelites.

Work carried out under R&D item on mass balance studies across the zones of
alteration, sericitisation and chloritisation within the rocks of Tosham tin prospect,
Bhiwani district, Haryana, has revealed alterations involving chloritisation, ...

Atlas of the textural patterns of granites, gneisses and ...
Sericitisation and alteration of variable extent is only indicated by the
plagioclases; in contrast, the K-feldspars are free of alteration (no sericitisation is
observed). The alteration of the plagioclases has taken place by "hydrothermal"
solutions ...

Atlas of Granitization: Textures and Processes
607 shows plagioclases enclosed in a K-feldspar megablast. Alteration
processes resulting in sericitisation have taken place in both feldspars, however,
the plagioclases are more altered due to their susceptibility to alteration. This is a
typical ...

Alternatively, ihey could represent zones of the Marybank Formation affected by
pervasive sericitisation. Mica-rich samples examined have conspicuous strain-
slip cleavage. In terms of mineral facies, rocks of the Wakapuaka Phyllonite are ...

Irregular and scattered sericitisation of plagioclase is observed in most of the
samples. In particular, the smaller plagioclase laths are more sericitised. The phe
- nocrysts of plagioclase are less altered and mostly fresh, though may be cloudy.

... slight sericitisation of feldspar, chloritisation of about 50% of biotite, and less
than 1% development of epidote; Bo26 exhibited slight sericitisation of feldspar,
chloritisation of about 30% of biotite, and less than 0-5% development of epidote.

... Island (P43808) contains subhedral microphenocrysts of twinned, often
glomeroporphyritic augite with some sericitisation and reaction rims of opaques,
sphene and chlorite. It also contains 1-2 mm wide zones of anhedral granular
and ...

Stibnite-bearing quartz lodes are almost invariably locussed in fiactures that are

inner zone of quartz-topaz alteration and an outer zone of sericitisation wherein ...
