As part of Metal Earth project, a total of km long 2D seismic lines are gathered across the Canadian Shield in Quebec and Ontario Provinces in Fall The seismic data were collected with long offsets and various spatial sampling scenarios. High resolution 2D/3D seismic surveys performed for the Geological Survey of Canada to advance the use of seismic methods in hard rock environments. Organization: Natural Resources Canada Lithoprobe transect 10 - Eastern Canadian Shield Onshore-Offshore Transect.

Careful measurements of phase velocities in the Canadian shield have been made in the period range 3 to 90 sec for Rayleigh waves and 12 to 60 sec for Love waves by phase correlation of wave trains. The continental Love wave phase velocity data are the first to be reported in the by: During the early Forties the first geophysical surveys (gravity and seismic) were undertaken in selected areas. They led to discovery of the Jumping Pound, Sarcee and Pincher Creek gas fields. A stimulating synthesis of geologic and geophysical data was published by Link (). During the Fifties extensive regional seismic surveys were.

No seismic profiling. Summary. In –88 a deep seismic reflection survey was conducted over the Kapuskasing structural zone (KSZ) in the Canadian shield as a part of the LITHOPROBE Project.

Approximately km of vibroseis data were acquired along 9 profiles which crossed the boundaries between the KSZ and Val Rita Block to the west and between the KSZ and Cited by: 5.

Lower St. mic surveys focussed primarily on deep mineral exploration: the Oryx survey in the Witwatersrand Basin, South Africa (De Wet and Hall, ); the Trill survey in Sudbury, Canada (Milkereit et al., this volume); and the Matagami survey, in the northern Abitibi subprovince of the Canadian shield (Adam et al., this volume).

These three surveys sample. Seismic survey, method of investigating subterranean structure, particularly as related to exploration for petroleum, natural gas, and mineral deposits.

The technique is based on determining the time interval that elapses between the initiation of a seismic wave at a selected shot point. A full suite of geophysical logs, including nuclear, electric, acoustic transit-time, acoustic waveform, and acoustic televiewer logs, and high-resolution flowmeter measurements have been used to investigate the lithologic and hydrologic properties of three igneous plutons located on the southern margin of the Canadian shield.

Two high‐resolution surveys in the Swayze area, a poorly endowed part of the western Abitibi greenstone belt, served as pioneer surveys with which to better understand subsurface geology and design a strategy to process other surveys in the near future.

Swayze seismic data were acquired with crooked survey geometries along : Saeid Cheraghi, Mostafa Naghizadeh, David Snyder, Rasmus Haugaard, Thomas Gemmell.
