None of the existing models for calc-alkaline “Late Granite”(Siluro–Devonian) genesis in the
metamorphic Caledonian orogenic belt of Ireland and Scotland fully explains their spatial …

Abstract The Caledonides of Britain and Ireland are one of the most intensively studied
orogenic belts in the world. This review considers all the tectonic events associated with the …

Avalonian-Cadomian and related terranes of the circum–North Atlantic constitute portions of
an accretionary orogen that developed on an active Gondwanan margin at the periphery of …

Ordovician orogeny affected the Laurentian margin of the Appalachian-Caledonian Belt from
the Southern Appalachians to the British Isles and is dated, stratigraphically, as post …

Detrital zircons in siliciclastic units of the Dalradian Supergroup yield U–Pb ages ranging
from 3.2 to 0.5 Ga. Detrital zircons from the sub-Grampian Group basement and the …

The Archaean Minto Block, northeastern Superior Province, is dominated by tonalite–
trondhjemite, enderbite (pyroxene tonalite), granodiorite and granite, with subordinate mafic …

U-Pb geochronological data from the Connemara region of Ireland indicate that continental
arc magmatism along the southern margin of Laurentia was short-lived, lasting only from ca …

Understanding the evolution and destruction of past oceans not only leads to a better
understanding of earth history, but permits comparison with extant ocean basins and …

New U-Pb single-zircon geochronology undertaken on tonalitic gneisses, granite sheets,
migmatites and metasediments from the Lewisian Gneiss Complex on the mainland and the …

The Dalradian Supergroup and its basement rocks, together with younger plutons, underpin
most of the Grampian Highlands and the islands of the Inner Hebrides between the …
