Concentrations of dykes of basic composition emplaced in the same igneous episode or
along similar trends are known as mafic dyke swarms and they occur in a wide variety of …

The identification of large igneous provinces (LIPs) and associated mantle plumes has been
confined for the most part to the Mesozoic and Cenozoic record. With few exceptions, pre …

In the high grade gneiss terranes of the Grenville Province in Ontario, metagabbro with
silicate coronas around primary olivine and Fe-Ti oxide contains trace amounts of both …

A paleomagnetic study of the western end of the∼ 585 Ma Grenville dyke swarm shows that
individual dykes are characterized by high coercivity and unblocking temperature …

The Grenville orogenic cycle, between∼ 1190 and 980 Ma, involved accretion of magmatic
arcs and/or continental terranes to the Laurentian craton. A transect across the western …

The Central Gneiss Belt, southwestern Grenville Province, is characterized by
parautochthonous crust in the north and allochthonous lithotectonic domains in the south …

Previous views based on the paleomagnetic history of Baltica compared with that of
Laurentia indicate a period of independent movement between∼ 1200 and 950 Ma, during …

The 1992 Lithoprobe Abitibi–Grenville Seismic Refraction Experiment was conducted using
four profiles across the Grenville and Superior provinces of the southeastern Canadian …

In western Labrador, tectonic elements of the parautochthonous belt of the northern
Grenville orogen include a regional, mid-crustal, thin-skinned, metamorphic fold-thrust belt …

Approximately 1350 km of multichannel seismic reflection data and an equivalent amount of
seismic refraction data have been collected across the North American Great Lakes. the …
