Non-volcanic continental margins may form up to 30% of all present-day passive margins, and remnants of them are preserved in mountain belts. The papers in this volume demonstrate the benefits of integrating offshore and onshore studies, and illustrate the range of information obtained at different scales when comparing evidence from land and sea. Data sets collected across a range of spatial. The rugged and pristine coast of Labrador in north-east Canada.

Unlike the deep mantle and crustal sections discussed above, which we have only been able to examine by indirect seismic methods, it has been possible to study the uppermost km of the section at Site directly because the section was drilled and continuously cored to a depth of m during Leg in order to install the borehole seismic observatory in basement below the influence of.

This textbook is designed to aid the student in geological map interpretation. The book starts with basic concepts such as dip and strike, and progresses through a variety of exercises based on folds, faults and unconformities, up to and including the interpretation of Geological Survey Maps.

In order to give a sense of reality to the text, frequent reference is made to actual examples on. The Moho-proxy maps using the two sets of depth to basement constraints (Figs 4a and b) show a relatively uniform Moho depth of 12 km in the centre of the Labrador Sea with a deeper Moho (20 km and greater) beneath the Davis Strait and for the offshore extension of the Grenville Province of southeastern Labrador.

These interpretation maps originated in the mid s when large airborne geophysical, magnetic and radiometric surveys were commonplace. Deep seismic reflection profiling has been used to outline the main features of the basement topography of the Labrador Sea. Two major sedimentary reflectors, tentatively dated as Paleocene and Eocene, are correlated throughout the survey.

Geophysical data collected from to during a systematic mapping program of the Labrador Sea have been analysed to investigate its geological history and evolution.

The data have been used to establish the location of the ridge axis, the age of the ocean floor, and the direction of movement of Greenland relative to North America. The Geological Survey of Newfoundland and Labrador is a scientific research agency that is part of the Department of Natural Resources of the Government of Newfoundland and Labrador.

It is the agency responsible for performing geological mapping and surveying which provides geological maps, reports, and mineral analysis, and for developing Newfoundland and Labrador's natural resources and Annual budget: approx.
