...SUSAN J. AITCHESON Abstract Samples from the Kalak Nappe Complex, north Norwegian Caledonides, have yielded the following ranges of Nd depleted-mantle model ages: orthogneiss 2.8 Ga; paragneisses 1.2-1.8 Ga; and Sørøy Succession metasediments 1.2-2.0 Ga. The presence in the Complex of sedimentary...

...R. D. DALLMEYER Abstract The Kalak Nappe Complex is composed of variably retrogressed, middle Proterozoic basement and imbricated, polydeformed, metasedimentary cover successions which, at least in part, appear to have originated within the late Proterozoic-early Palaeozoic Baltoscandian...

...C.L. Kirkland; J.S. Daly; M.J. Whitehouse Abstract Three orogenic events, Porsanger (pre-800 Ma), Finnmarkian (490–540 Ma) and Scandian (400–425 Ma) have been proposed to explain the evolution of the Kalak Nappe Complex, a major component of the Caledonian orogen in Norway. The Kalak Nappe Complex...

... is thrust over the Kalak complex. The time sequence for deformation proposed by the authors, based upon dating of the syn-orogenic igneous bodies of the Seiland Igneous Province in W Finnmark, can be correlated, at least in part, with textural features exhibited by the Kalak units. This has particular...

...B. A. Sturt; I. R. Pringle; D. M. Ramsay Abstract The Kalak nappe complex of N Norway involves late Precambrian to Middle Cambrian sediments and a Precambrian gneiss basement on which the sediments were deposited. While the uppermost nappe in Finnmark was emplaced during the Silurian the members...

... retention temperatures at ca. 1700-1800 Ma following the Sveco-karelian orogeny. The extent of whole-rock spectra discordancy is related to the proximity of the basal thrust of the structurally overlying Kalak Nappe Complex. Whole-rock sample suites were also collected structurally downward (0.6-20 m) from...

... the underlying Kalak nappe complex. It is therefore inferred that the Scandian emplacement of the Magerøy nappe was synchronous with a thermal event which affected the older and underlying Finnmarkian-defor-med Kalak nappe complex.

... evidence of new zircon growth during the Caledonian metamorphism. The carbonatite was emplaced into the Kalak Nappe Complex at 574 ± 5 Ma, and various alkaline gneisses and nepheline syenite dykes intruded the neighbouring Breivikbotn Gabbro and its metasedimentary host between 580 and 560 Ma. The alkaline...
