The Baltimore Gneiss domes of the Maryland Piedmont

2004
Gneiss domes in the Maryland Piedmont near Baltimore contain a wide variety of metamorphic rock types, all metamorphosed to amphibolite grade and collectively named Baltimore Gneiss. Most were derived from interlayered sedimentary and volcanic rocks into which granitic plutons were emplaced in both Precambrian and Paleozoic time.

The origin of contractional structures in extensional gneiss domes

Geology, 2017
Abstract The juxtaposition of domains of shortening and extension at different scales in orogens has fueled many debates about driving forces and tectonic interpretations, including timing of deformation. At the orogen scale, gravitational collapse and mass transfer from orogenic plateaux to forelands explain some of these juxtapositions.

Shelburne Falls gneiss dome, Massachusetts

Eos, Transactions American Geophysical Union, 1945
The Shelburne Falls gneiss dome, in the eastern Berkshire Hills of northern Massachusetts, consists of amphibolitic metavolcanics, intruded by sills and complex lit‐par‐lit injection‐zones of a quartz‐diorite and its associated volatiles. The dome is surrounded on all sides by the Conway schist, of early Paleozoic age.The dome surface dips outward at ...

GNEISS DOME AT SHELBURNE FALLS, MASSACHUSETTS

Geological Society of America Bulletin, 1946
The Shelburne Falls gneiss dome, in the eastern Berkshire Hills of western Massachusetts, consists of amphibolitic metavolcanics, intruded by sills and complex lit-par-lit injection zones of a quartz diorite and its associated volatiles. The dome is surrounded by the Conway schist of early Paleozoic age. The principal rock types are described.

Gneiss Dome Formation in the Himalaya and southern Tibet

Geological Society, London, Special Publications, 2019
Abstract Gneiss domes in the Himalaya and southern Tibet record processes of crustal thickening, metamorphism, melting, deformation and exhumation during the convergence between the Indian and Eurasian plates. We review two types of gneiss domes: North Himalayan gneiss domes (NHGD) and later domes formed by orogen-parallel extension.

The problem of mantled gneiss domes

Quarterly Journal of the Geological Society of London, 1948
In many orogenic zones there occur domes having a superincumbent mantle of sedimentary strata layered parallel to the dome contacts and the foliation of the gneiss. In the Karelidic zone of East Finland are numerous domes showing somewhat different development.

Structural evolution of the Thor-Odin gneiss dome

Tectonophysics, 1984
Abstract The Thor-Odin dome is a large structural culmination along the eastern margin of the Shuswap terrain. Previous workers have presented divergent models for the origin of the dome. Some have proposed that it is a product of diapiric uprise of material from the lower crust; alternatively, the dome is interpreted to have formed from the ...
