Bridging and Conformational Control of Porphyrin Units through Non-Traditional Rigid Scaffolds

Grover, Nitika; Locke, Gemma M.; Flanagan, Keith J.; Beh, Michael H. R.; Thompson, Alison; Senge, Mathias O. (Wiley, 2019-11)

Connecting two porphyrin units in a rigid linear fashion, without any undesired electron delocalization or communication between the chromophores, remains a synthetic challenge. Herein, a broad library of functionally ...

Paleoenvironmental Analysis of Halifax Harbour: Sedimentology, Paleoclimatology, and Holocene Sea Level

Edgecombe, Roger B. (1994-03-15)

Three cores (numbered 2,9,10) collected from Halifax Harbour using new submersible vibracoring equipment permits a reinterpretation of an acoustically distinct seismostratigraphic unit. This unit, never previously sampled, ...

Sediment Consolidation and Permeability at the Central Oregon Margin, Ocean Drilling Program Sites 891 and 892

Gray, William G. D. (1994-03-15)

Sediment hydraulic conductivity is a critical and highly variable control on the consolidation of accretionary prism materials. The consolidation state and pore pressure conditions within an accretionary prism ultimately ...

Geochemistry and Petrogenesis of Late Cretaceous Bentonites from the Kanguk Formation, Axel Heiberg and Ellesmere Islands, Canadian High Arctic

Parsons, Michael B. (1994-03-15)

Petrographic and geochemical analyses of bulk bentonites, volcanic minerals, and unaltered glass inclusions in quartz phenocrysts reveal the composition and tectonic setting of Late Cretaceous explosive volcanism in the ...

Physical Volcanology, Petrology, and Petrogenesis of the Cretaceous Isachsen Formation Volcanics, Western Axel Heiberg Island, N.W.T.Formation Volcanics, Western Axel Heiberg Island, N.W.T.

Pearson, Eric W. (1994-03-15)

New data from Bjarnasson Island and Bals Fiord on western Axel Heiberg Island provide insight into the physical volcanology, petrology, and petrogenesis of Cretaceous Isachsen Formation magmatism. The Bjarnasson Island ...

GEOMETRY AND DEPOSITIONAL SETTING OF THE LATE CARBONIFEROUS MULLINS COAL IN THE SOUTH BAR FORMATION, SYDNEY BASIN, NOVA SCOTIA

Tibert, Neil Ernest (1994-03-15)

The three-dimensional geometry of the Mullins Coal (Westphalian C) provides information about its origin and potential for commercial exploitation. Controls for peat accumulation are allogenic in contrast to a previous ...

Comparison of Siliceous Volcanics from the Clarno and John Day Formations, Oregon

Atheim, Brian K. (1993-03-15)

The Tertiary Clarno and John Day Formations occur in the Blue Mountains Region of north-eastern Oregon. The two formations are easily distinguishable overall, because the Clarno consists primarily of andesitic to dacitic ...

Holocene Relative Sea-Level Change in Nova Scotia

Brown, Kendrick (1993-03-15)

Core samples collected around Atlantic Canada, specifically from the West Head salt marsh, Chezzetcook Inlet, enable temporal and spatial examination of benthic foraminiferal assemblages. Benthic foraminiferal zonations, ...

40Ar/39Ar Thermochronology Across a Transect of the Eastern Grenville Front Tectonic Zone and the Western Britt Domain of the Grenville Province, Georgian Bay

Grant, Steven L. (1993-03-15)

40Ar/39Ar thermochronology of hornblendes from granitic gneiss and amphibolites in the Central Gneiss Belt (CGB) west of Key Harbour along northern Georgian Bay yields ages ranging from 1016 - 995 Ma. Muscovites from the ...

Structure of the Dunamagon Granite, Baie Verte Peninsula, Newfoundland

McDonald, Laurel (1994-03-15)

New Structural data from field observations and microstructural analysis are the basis of description of structures in the Dunamagon Granite, for the purpose of determining whether it has an intrusive, or tectonic, contact ...

Paleoceanographic Reconstruction of the Inner Scotian Shelf During the Younger Dryas: A Benthic Foramineral Study

Costello, Oran P. (1994-03-15)

Examination of foraminifera from piston core 91-018-53P permits a paleoceanographic reconstruction of the Inner Scotian Shelf, with emphasis on the Younger Dryas cold period. A minimum in the total number of foraminifera ...

Contact Relations Between The New Ross Leucomonzogranite and the Falls Lake Mafic Porphyry: Evidence for Magma Interactions in the South Mountain Batholith

DeWolfe, Vincent C. (1994-03-15)

The South Mountain Batholith is a peraluminous composite batholith that intruded over a short interval of time. The batholith consists of 260 intrusive bodies, thus the possibility of magma-magma interactions is high. The ...
