Insights into magmatism in volcanic margins: bridge structures and a new mechanism of basic sill emplacement – Theron Mountains, Antarctica

Autor: D. H. W. Hutton

Publikováno v: Petroleum Geoscience. 15:269-278

Basic, doleritic sills form a key component of subvolcanic complexes in the prospective parts of volcanic margins where they add considerably to the structural and thermal complexity of the subsurface geology. Whilst recent 3D seismic studies of sill

A structural cross-section from the Aureole of the Main Donegal Granite

Autor: D. H. W. Hutton

Publikováno v: Geological Journal. 12:99-112

Seven phases of deformation are recognised in Dalradian metasediments within the NW aureole of the Main Donegal Granite. Major NW facing F2 folds (the Aghla Anticline and Errigal Syncline) refold an originally NW facing slaty cleavage, which is usual

Metadolerite age relationships in the Dalradian of northwest Donegal, Ireland and their orogenic significance

Autor: D. H. W. Hutton

Publikováno v: Geological Journal. 14:171-178

The structural relationships of several intrusive sheets belonging to the extensive metadolerite suite of the Appin (lower) Dalradian rocks of the Creeslough area, northwest Donegal, Ireland have been examined. It is concluded that, relative to the r

Publikováno v: Economic Geology

Gold vein mineralization occurs in the metamorphosed and deformed Dalradian (Neoproterozoic) rocks of the Sperrin Mountains, Northern Ireland. Two structures exerted a control on the location of the mineralization; the north-south Omagh lineament and

Evidence for sinistral shear associated with the emplacement of the early Devonian Etive dyke swarm

Strike-slip tectonics and granite petrogenesis

Autor: D. H. W. Hutton, R. J. Reavy

Publikováno v: Tectonics. 11:960-967

Transpression is a process that thickens the crust and therefore in obliquely convergent orogens as in normally convergent orogens there is the potential to generate granitic melts. Individual transcurrent shear zones may not only control the ascent

The rapakivi granites of S Greenland—crustal melting in response to extensional tectonics and magmatic underplating

Autor: P. E. Brown, T. J. Dempster, T. N. Harrison, D. H. W. Hutton

Publikováno v: Earth and Environmental Science Transactions of the Royal Society of Edinburgh. 83:173-178

Early Proterozoic rapakivi intrusions in S Greenland occur as thick sheets which have ramp–flat geometry and were intruded along the median planes of active ductile extensional shear zones. These shear zones and their intrusions were linked via tra
