Infiltration may have been the dominant mechanism during contact metamorphism
, with H2O-rich fluids derived from the crystallization of a granodiorite intrusion penetrating calcareous rocks in the contact aureole giving rise to a skarn-type mineralogy and the formation of Ti-clinohumite.

of siliceous carbonate rocks from the Ballachulish aureole, Scotland: Contribution to Mineralogy and Petrology, v.
However, this mineral sequence was probably affected by contact metamorphism
which could explain analcime formation accompanied by decreasing Si activity and increasing temperature (not reflected in Figure 8) In the Si[O.
5, Table la, b), despite their potential association with magmatic fluids during contact metamorphism
On one specific sample, with evidence of contact metamorphism
, microstructures were described in more detail in order to characterize those linked to contact metamorphism
From all these plutons only the La Paya granite, emplaced in schists of medium-grade metamorphism, is surrounded by an aureole of contact metamorphism
1996) noted that contact metamorphism
of folded strata of the Stirling belt by the Chisholm Brook suite implies that folding of the Stirling belt can be bracketed between ca.
This intrusive body is responsible for the classic contact metamorphism
and skarn mineralogy that exists at Crestmore.
Furthermore, a low-grade contact metamorphism
has been identified in the sedimentary host-rocks at the Moncayo sector (Bastida et al.
2006) have been demonstrated to be the result of contact metamorphism
of the Goldenville and Halifax groups around Devonian and Carboniferous granitoid plutons (White et al.
and metasomatism occurred at the margins of the pluton and in large roof pendants of limestone that were converted to skarns.
However, since they appear to be absent elsewhere in the inlier, there is reason to believe that they are products of contact metamorphism
within the thermal aureole of the intrusion.
