Mantled Gneiss Domes in the Albion Range, Southern Idaho
Geological Society of America Bulletin, 1968The Albion Range, in southern Idaho east of the Antler orogenic belt and west of the Sevier orogenic belt, exposes a northeast-trending chain of four mantled gneiss domes. The Green Creek Complex (Precambrian [2.5 b.y.] gneiss and metasediments), which forms the cores of the domes, is unconformably overlain by the Paleozoic Dove Creek Group, consisting

Journal of Structural Geology, 1982
Abstract Gneiss domes and plutonic granitoid domes make up almost 50% of the pre-Hercynian terrains in the Central and Eastern Pyrenees. From a structural study of the shape and internal structure of the domes and of their relationships with the enclosing rocks, it can be shown that both types of domes were emplaced diapirically during the major ...

Basement gneiss domes in the Svecokarelides of eastern Finland: discussion
Earth and Planetary Science Letters, 1981A recent paper in this journal (J.-P. Brun, The cluster-ridge pattern of mantled gneiss domes in eastern Finland: evidence for large-scale gravitational instability of the Proterozoic crust, Earth Planet. Sci. Lett. 47 (1980) 441-449) resurrects Eskola's [1] concept of the mantled gneiss dome in the early Proterozoic Svecokarelian fold belt of Finland.

Fold nappes as asymmetric mantled gneiss domes and ensialic orogeny
Tectonophysics, 1974Abstract Descriptions are presented of the development of asymmetric gravity-driven structures rising from wedge-shaped bodies of light fluids overlain by denser fluids. Two programmes of experiments are described: 1. (1) the stabilization of wedges of oil overlain by glucose syrup in the field of gravity 2.

NEOPROTEROZOIC AND DEVONIAN GRANITES OF THE KOOLENSKY GRANITE-GNEISS DOME, ARCTIC CHUKOTKA
Tikhookeanskaya GeologiyaNew U-Pb zircon dating of rock samples from the core of the Koolensky granite-gneiss dome in Chukotka yielded a Neoproterozoic age (650–530 Ma) for the orthogneisses and a Devonian age (390–360 Ma) for the granitoids. Devonian granites and quartz monzonites are assigned to the peraluminum magnesian calc-alkaline varieties of volcanic arc granitoids ...
