The East Greenland rifted volcanic margin

Autor: C. Kent Brooks

Publikováno v: Geological Survey of Denmark and Greenland Bulletin, Vol 24, Pp 1-96 (2011)

The Palaeogene North Atlantic Igneous Province is among the largest igneous provinces in the world and this review of the East Greenland sector includes large amounts of information amassed since previous reviews around 1990.The main area of igneous

Bulk Liquid for the Skaergaard Intrusion and Its PGE-Au Mineralization: Composition, Correlation, Liquid Line of Descent, and Timing of Sulphide Saturation and Silicate–Silicate Immiscibility

Autor: C. Kent Brooks, Troels F.D. Nielsen, Jakob K. Keiding

Publikováno v: Journal of Petrology. 60:1853-1880

Preferred and modelled bulk composition of the Skaergaard intrusion are compared to coeval basaltic compositions in East Greenland and found to relate to the second evolved cycle of Geikie Plateau Formation lavas and coeval Skaergaard-like dikes in m

Petrogenesis of Cogenetic Silica-Oversaturated and -Undersaturated Syenites by Periodic Recharge in a Crustally Contaminated Magma Chamber: the Kangerlussuaq Intrusion, East Greenland

Autor: Christian Tegner, David W. Peate, C. Kent Brooks, J. Richard Wilson, Morten S. Riishuus

Publikováno v: Journal of Petrology. 49:493-522

The Palaeogene Kangerlussuaq Intrusion (∼50 Ma) of East Greenland displays concentric zonation from quartz-rich nordmarkite (quartz syenite) at the margin, through pulaskite, to foyaite (nepheline syenite) in the centre; modal layering and igneous

Autor: Chris Harris, Christian Tegner, Morten S. Riishuus, C. Kent Brooks, David W. Peate, J. Richard Wilson

Publikováno v: Riishuus, M S, Harris, C, Peate, D W, Tegner, C, Wilson, J R & Brooks, C K 2015, ' Formation of low-δ 18 O magmas of the Kangerlussuaq Intrusion by addition of water derived from dehydration of foundered basaltic roof rocks ', Contributions to Mineralogy and Petrology, vol. 169, no. iss. 5,, Art.no. 41 . https://doi.org/10.1007/s00410-015-1134-7

The Kangerlussuaq Intrusion in East Greenland is concentrically zoned from quartz nordmarkite (quartz syenite) at the margin, through pulaskite, to foyaite (nepheline syenite) in the centre, with no apparent intrusive contacts. The δ18O values of co

Temporal evolution of a long-lived syenitic centre: The Kangerlussuaq Alkaline Complex, East Greenland

Autor: Morten S. Riishuus, David W. Peate, C. Kent Brooks, Chris Harris, J. Richard Wilson, Christian Tegner

Publikováno v: Lithos. 92:276-299

We present new mineral and whole-rock compositions and Sr–Nd–Hf–Pb–O–H isotope data on samples from the Kangerlussuaq Alkaline Complex (∼ 1000 km2) in central East Greenland, part of the North Atlantic Igneous Province. This complex mainl

Ultra-depleted, shallow cratonic mantle beneath West Greenland: dunitic xenoliths from Ubekendt Ejland

Autor: Peter B. Kelemen, Karen Hanghøj, Stefan Bernstein, C. Kent Brooks

Publikováno v: Contributions to Mineralogy and Petrology. 152:335-347

Dunitic xenoliths from late Palaeogene, alkaline basalt flows on Ubekendt Ejland, West Greenland contain olivine with 100 × Mg/(Mg + Fe), or Mg#, between 92.0 and 93.7. Orthopyroxene has very low Al2O3 and CaO contents (0.024–1.639 and 0.062–0.2

Re-Os AND 40Ar/39Ar AGES OF PORPHYRY MOLYBDENUM DEPOSITS IN THE EAST GREENLAND VOLCANIC-RIFTED MARGIN

Autor: Bjorn Thomassen, Christian Tegner, Holly J. Stein, C. Kent Brooks

Publikováno v: Economic Geology. 99:1215-1222

Precise Re-Os dating of molybdenite from the Malmbjerg and Flammefjeld rift-related porphyry molybdenum deposits indicates that they are among the youngest magmatic events (25.8 ± 0.1 and 39.7 ± 0.2 Ma) in their respective areas of the East Greenla
