The model therefore ignores the effects of any horizontal loads that might arise as a consequence of ophiolite emplacement .
However, the emplacement of these granites is still poorly constrained.
However, this mode of emplacement is contradictory to well-established ideas for Archaean granites in the Zimbabwe craton.
The scarcity of evidence from magmatic fabrics for granite emplacement during regional shortening may reflect the general persistence of deformation to sub-solidus states.
a gun emplacement
The abundance of magmatic layering in this granite affords an unusual glimpse of early emplacement processes.
In some instances, there is clear evidence for the accompanying emplacement of mantle-derived mafic magmas, providing a source for the anomalous heating.
Of these, only the emplacement and structure of the Strontian Granite has been studied in detail.
They probably represent the time of igneous emplacement of the granitic source rocks.
In both cases, the sequence of events started with extensional basin magmatism and culminated in emplacement of plutons, passing through basin subsidence.
