The Henkel Petrophysical Plot: Mineralogy and Lithology From Physical Properties

Autor: William A. Morris, T. S. Hamilton, R J Enkin

Publikováno v: Geochemistry, Geophysics, Geosystems. 21

The Henkel plot (logarithm of magnetic susceptibility versus density of rock samples) reveals that most rocks fall on either a “magnetite trend” or a “paramagnetic trend”. I...

Stratigraphy of the Gorges moraine system, Mount Kenya: palaeosol and palaeoclimate record

Autor: René W. Barendregt, T. S. Hamilton, William C. Mahaney, Dez L. Tessler, Ronald G.V. Hancock, Pedro Costa

Publikováno v: Journal of the Geological Society. 170:497-511

Moraines marking an Early Pleistocene glaciation on Mt. Kenya are known from several valleys along the eastern and southeastern flanks of the mountain. The most prominent group of end moraines delimiting the lowermost extent of the Early Pleistocene

Episodic Volcanism in the Buck Creek Complex (Central British Columbia, Canada): A History of Magmatism and Mantle Evolution from the Jurassic to the Early Tertiary

Autor: J. V. Owen, T. S. Hamilton, B. N. Church, Jaroslav Dostal

Publikováno v: International Geology Review. 47:551-572

The Buck Creek volcanic complex of the Intermontane Superterrane of the Canadian Cordillera records a long history of volcanic activity from the Cretaceous through to the Eocene, when magmatic activity peaked, to the Miocene. Its basement includes pr

Eocene melting of Precambrian lithospheric mantle: Analcime-bearing volcanic rocks from the Challis–Kamloops belt of south central British Columbia

Autor: Derek J. Thorkelson, Jaroslav Dostal, B. N. Church, K. Breitsprecher, T. S. Hamilton

Publikováno v: Journal of Volcanology and Geothermal Research. 126:303-326

Potassic silica-undersaturated mafic volcanic rocks form a minor portion of the predominantly calc–alkaline Eocene Challis–Kamloops volcanic belt, which extends from the northwestern United States into central British Columbia (Canada). Their maj

A near-ridge origin for seamounts at the southern terminus of the Pratt-Welker Seamount Chain, northeast Pacific Ocean

Autor: Jarda Dostal, Brian Cousens, T. S. Hamilton

Publikováno v: Canadian Journal of Earth Sciences. 36:1021-1031

Three seamounts close to the south end of the Pratt-Welker Seamount Chain, Gulf of Alaska, have been sampled to test whether or not mantle plume-related volcanism extends south of Bowie Seamount. Lavas recovered from Oshawa, Drifters, and Graham seam

Continental signature of a ridge-trench-triple junction: Northern Vancouver Island

Autor: C. Lowe, T. S. Hamilton, T. J. Lewis

Publikováno v: Journal of Geophysical Research: Solid Earth. 102:7767-7781

South of the Juan de Fuca-Pacific-North America triple junction located off northern Vancouver Island there is subduction, and to the north there is oblique convergence along the Queen Charlotte transform fault. In the mid-Tertiary, periods of extens

Queen Charlotte Area Cenozoic tectonics and volcanism and their association with relative plate motions along the northeastern Pacific Margin

Autor: T. S. Hamilton, Roy D. Hyndman

Publikováno v: Journal of Geophysical Research: Solid Earth. 98:14257-14277

Cenozoic relative plate interactions along the Queen Charlotte margin, based on published models for the North America and northeast Pacific plates, are related to the tectonic and igneous history of the region. Plate motion models indicate convergen

High-resolution acoustic mapping of shallow gas in unconsolidated sediments beneath the strait of Georgia, British Columbia

Autor: T. S. Hamilton, B. S. Hart

Publikováno v: Geo-Marine Letters. 13:49-55

Gassy sediments are detectable acoustically in subbottom profiles of Canada's Fraser Delta slope and prodelta areas. Interstitial gas is typically represented by zones of acoustic turbidity on high-resolution seismic profiles and by gas brightening o
