A XENOLITH-BASED LITHOSPHERIC TRANSECT OF THE SLAVE CRATON, N.W.T., CANADA [PDF]

open access: yes, 2012
During the last decade, the Canadian Slave craton has emerged as an important global diamond resource. Recent work on the sub-continental lithospheric mantle (SCLM) beneath this craton has yielded tantalising suggestions about its structure and ...

Lithospheric Architecture and Mantle Metasomatism Linked to Iron Oxide Cu‐Au Ore Formation: Multidisciplinary Evidence from the Olympic Dam Region, South Australia

open access: yesGeochemistry, Geophysics, Geosystems, 2018
The role of lithospheric architecture and the mantle in the genesis of iron oxide copper‐gold (IOCG) deposits is controversial. Using the example of the Precambrian Gawler Craton (South Australia), which hosts the giant Olympic Dam IOCG deposit, we ...

Ultramafic xenoliths from the Bearpaw Mountains, Montana, USA: evidence for multiple metasomatic events in the lithospheric mantle beneath the Wyoming craton

open access: yes, 2004
Ultramafic xenoliths in Eocene minettes of the Bearpaw Mountains volcanic field (Montana, USA), derived from the lower lithosphere of the Wyoming craton, can be divided based on textural criteria into tectonite and cumulate groups. The tectonites consist

Influence of the Hainan Plume on the Deep Thermal Structure and Shallow Geothermal Field of Southeastern Coastal China

open access: yesJournal of Marine Science and Engineering
Thermal anomalies within the lithosphere are an important manifestation of mantle plume–lithosphere interaction. Early studies primarily concentrated on the presence of the Hainan plume and its surface responses, with comparatively little research ...

Re-os isotope constraints on the age of the Lithospheric mantle beneath western Greenland. [PDF]

open access: yes, 2007
Alkaline magmatic activity across Western Greenland (W.G.) provides a record of lithosphere evolution over the last 600 Ma. Ultra Mafic Lamprophyre (UML) magmatism in particular has erupted an exceptional inventory of mantle xenoliths allowing a detailed

The development of magmatism along the Cameroon Volcanic Line: Evidence from teleseismic receiver functions

open access: yes, 2012
[1] The Cameroon Volcanic Line (CVL) in West Africa is a chain of Cenozoic volcanism with no clear age progression. The reasons for its existence are unclear, and the nature of its magmatic plumbing system is poorly understood.

Mafic alkaline metasomatism in the lithosphere underneath East Serbia: evidence from the study of xenoliths and the host alkali basalts

open access: yes, 2010
Effects of mafic alkaline metasomatism have been investigated by a combined study of the East Serbian mantle xenoliths and their host alkaline rocks.

East Pilbara high heat flow mantle overturns as a record of lithospheric proto-plate formation

open access: yes, 2023
The ca. 3.6-3.2 Ga East Pilbara Terrane (EPT) formed by a distinct vertically accretive geodynamic mode during predicted highest planetary heat flow, prior to the onset of Wilson-style plate tectonics at ca. 3.2 Ga. Three major greenstone volcanic cycles

The backarc mantle lithosphere in Patagonia, South America

open access: yesJournal of South American Earth Sciences, 2004
The backarc Patagonia mantle underwent pervasive regional re-crystallisation that left only remnants of the pre-existing mantle. Anhydrous xenoliths (dominantly lherzolites and harzburgites, few dunites) are predominant. Xenoliths containing hydrous phases (lherzolites and harzburgites, rare wehrlites) abundantly occur only at G. Gregores.
