The southwestern panel occurs to the southwest of the Savage Island Shear Zone, contains pillowed and massive basalt, felsic volcanic rocks and volcanogenic sedimentary rocks, and can be traced unambiguously into panel I in the eastern portion of the belt. The Arctic Institute of North America initiated the Devon Island Expedition , the objectives of which are: (1) A study of the relationships between the marine environment (Jones Sound), the Devon Island Ice Cap, and the atmosphere, with special regard . 4. Since rocks found in Newfoundland are the same type and age as rocks found in Greenland, Ireland, Scotland, and Norway, it would appear that the world's major were continuous when the continents were joined. 5.

km2 area of northern Fiordland (South Island, New Zealand) is described in which Early Cretaceous high-pressure metamorphic rocks and virtually unmetamorphosed plutonic rocks occur.

The dominant rocks are orthogneisses developed from synmetamorphic basic-intermediate intrusive complexes, the youngest and most widespread of which is the Early Cretaceous Western Fiordland.

Granulite facies character of rocks studied by Bugge in the Arendal region has here been partially overprinted by later metamorphism and granitisation.

Abstract: Th e Palaeogene forearc sedimentary fi ll on Lemnos Island, NE Greece, was examined to determine reservoir characteristics and textural parameters. During this time interval the studied area was the site of accumulation of submarine fans that underlie shelf deposits, with tectonic activity responsible for the shallowing upward trend.

The high 3He/4He ratio of volcanic rocks thought to be derived from mantle plumes is taken as evidence for the existence of a mantle reservoir. I'd like to know what type of rock the green part of that rock is. It's very hard and it resists working it well.
