The architecture and pressure-temperature conditions reached by a Cretaceous block-in-matrix serpentinite mélange exposed in the Zagros suture resemble those imaged active Mariana subduction zone. There, large magnitude-earthquakes (M>w9) have never been recorded but smaller events – of poorly-constrained physical origin range M?w3-6 are widespread. Field petro-structural constraints led to fir...

What is it about patent legislation? Speaking for the Supreme Court in 1981, Justice Dickson, later Chief Justice, said of disclosure provision Patent Act (now subsection 27(3)) that: [i]t gives impression a melange ideas gathered at random rather than an attempt to enunciate, clearly and concisely, governing principle or principles. This perhaps understandable that section product amendment...

The northern part of the North Atlantic Craton (NAC) in southern West Greenland comprises a large tract exposed Meso-Neoarchaean continental crust, divided into ca 3300–2900 Ma Akia and 2900–2500 Tuno terranes. We combine aeromagnetic, stream sediment geochemical, new litho-chemical zircon geochronological data with previously published to re-evaluate crustal architecture evolution terrane its ...
