Highly refractory Archaean peridotite cumulates:Petrology and geochemistry of the Seqi Ultramafic Complex,SW Greenland
《Geoscience Frontiers》2018年第3期689-714,共26页Kristoffer Szilas Vincent van Hinsberg Iain McDonald Tomas Naeraa Hugh Rollinson Jacob Adetunji Dennis Bird 
Financial support to Kristoffer Szilas from Knud Hojgaards Fond for the fieldwork at the Seqi Ultramafic Complex;research grants VKR023371 from VILLUM FOUNDATION;CF16-0059 from CARLSBERG FOUNDATION made this study possible
This paper investigates the petrogenesis of the Seqi Ultramafic Complex, which covers a total area of approximately 0.5 km^2. The ultramafic rocks are hosted by tonalitic orthogneiss of the ca. 3000 Ma Akia terrane wi...

Stagnant lids and mantle overturns:Implications for Archaean tectonics, magmagenesis,crustal growth, mantle evolution, and the start of plate tectonics被引量：33
《Geoscience Frontiers》2018年第1期19-49,共31页Jean H.Bédard 
The lower plate is the dominant agent in modern convergent margins characterized by active subduction,as negatively buoyant oceanic lithosphere sinks into the asthenosphere under its own weight.This is a strong plate-...

Dominant Lid Tectonics behaviour of continental lithosphere in Precambrian times:Palaeomagnetism confirms prolonged quasi-integrity and absence of supercontinent cycles被引量：1
《Geoscience Frontiers》2018年第1期61-89,共29页J.D.A.Piper 
Although Plate Tectonics cannot be effectively tested by palaeomagnetism in the Precambrian aeon due to the paucity of high precision poles spanning such a long time period,the possibility of Lid Tectonics is eminentl...
