Geophysical, petrological, and geochemical data provide important clues about the
composition of the deep continental crust. On the basis of seismic refraction data, we divide …

Predictive relations are developed for ground motions from eastern North American
earthquakes of 4.0≦ M≦ 7.25 at distances of 10≦ R≦ 500 km. The predicted parameters …

The shape of the attenuation curve of the Fourier spectrum of acceleration is established for
southeastern Canada from empirical data. The dataset is comprised of 1200 digital vertical …

Source spectra for earthquakes of 3≤ M≤ 7 in eastern North America (ENA) are determined
from regional seismograph recordings, strong-motion records, teleseismic data, and …

Twenty‐two new determinations of heat flow and radiogenic heat production in the Superior
and Grenville provinces of the Canadian Shield are presented. The new data and previously …

Regional depth phase modeling is a useful technique to constrain earthquake focal depths
for events within sparse networks. We demonstrate how regional depth phases can be used …

We have developed a simple semblance-weighted stacking technique to estimate crustal
thickness and average VP/VS ratio using teleseismic receiver functions. We have applied …

There are three usable regional depth phases, sPg, sPmP, and sPn, and their
corresponding reference phases, Pg, PmP, and Pn. The differential time between each …

The Michipicoten greenstone belt (MGB), Wawa gneiss terrane (WGT), and Kapuskasing
structural zone (KSZ) in Ontario, Canada, are regarded as a 25‐km‐thick partial cross …

Calcite veins with accessory galena, sphalerite, barite and fluorite are abundant within the
Ottawa-Bonnechère and the Charlevoix-Saguenay failed arms of the St. Lawrence rift …
