A quiz based on the 224 Geophysics section sample paper.

Classroom Presentation - Overview

A general overview of Geophysics as applied to tectonics and exploration commences the segment. This relates the possible field measurements to physical properties by which rocks may differ.

Classroom Presentation - Modern Mapping

A piece on the place of geophysical and remote-sensing data in modern geological mapping follows (to introduce a lab exercise, not shown here).

Classroom Presentation - Magnetics Basics

Concentrating on magnetics, the concept of an anomaly, and the relationships which determine anomaly shapes, form most of the third part.

Classroom Presentation - Geological Controls on magnetic properties - Modelling

A discussion of the factors which affect the magnetic responses of rocks then follows, and the segment concludes with some simple case histories.
