Johnson & Pollard (7) recognise that laccolith formation is characterised by three distinct stages.
Kerr & Pollard23 introduce a laccolith model in which they treat the overburden of the pressurised magma as an elastic plate.
When assuming an intrusive origin of the dome Ha2, this would indicate that laccolith formation proceeded until the second stage, characterised by flexure of the overburden.
The smooth cross-sectional dome shape indicates that laccolith formation proceeded until the stage characterised by flexure of the overburden.

4) with the top half of the laccolith complex displaced at least 8 km eastward, a distance estimated from clasts of bornfels from the Monte Capanne aureole occurring in the footwall breccia at that distance.
The intrusive units of the pre-pluton laccolith complex are more acidic than the pluton, whereas the mafic microgranular enclaves are generally less acidic (Si[O.sub.2] from 61.5 to 68.3 wt%; Fig.
In addition, K-feldspar megacrysts from the San Martino laccolith, whose size, internal texture, and composition are similar to those from the Monte Capanne pluton, preserve a high-T structural state (sanidine): this observation lends further support to their igneous origin.
