Messinian deep-water turbidites and glacioeustatic sea-level changes in the North Atlantic: Linkage to the Mediterranean Salinity Crisis
(1996-06)
Our benthic foraminiferal data clearly indicate eight layers of deepwater turbidites during the Messinian (MTL 1-8) and one in the early Pliocene (PTL 1) in Ocean Drilling Program Leg 105, Site 646B. These deep-water ...
Last Gasp of the Grenville Orogeny - Thermochronology of the Grenville Front Tectonic Zone Near Killarney, Ontario
(1993-09)
We present U-Pb (titanite, zircon) and Ar-40/Ar-39 (hornblende, mica, K-feldspar) data from a transect across the western part of the Grenville Front Tectonic Zone (GFTZ) near Killarney, Ontario. High-grade metamorphic ...
The recent ice age
(Atlantic Geoscience Society, 1990-03)
Offshore oil and natural gas
(Atlantic Geoscience Society, 1992-05)
This documentary looks at the petroleum exploration industry off Canada's east coast in the early 1990s. It covers the geology of hydrocarbon formation in sedimentary rocks, the extraction of petroleum, supply chain safety, ...
Experimental Melting of Biotite Plus Plagioclase Plus Quartz Plus Or Minus Muscovite Assemblages and Implications for Crustal Melting
(1995-08)
In order to understand the role of mica-rich rocks as a source of granite magmas, a series of melting experiments was performed on two different starting materials. The first composition is a model biotite gneiss consisting ...
Stratigraphic model for glacial-eustatic Pennsylvanian cyclothems in highstand nearshore detrital regimes
(1998-07)
Lower (distal) positions on gently sloping shelves (ramps) affected by Pennsylvanian glacial-eustatic sea-level fluctuation display classic marine transgressive-regressive cyclothems, which are separated by exposure surfaces ...
