Chapter 7 — Exam Question 2

Make a list of the physical properties of rocks that have been used as the basis of geophy-

sical mapping methods.

Answer

Geophysical properties of rocks that are used as a basis for geophysical mapping
methods include:

1. the combination of radiometric isotopes (U, K and Th)

2. rock density (= gravity) anomalies and magnetic anomalies

3. water content

4. mineral composition (e.g., Ores)

5. electric conductivity and chargeability

Note that groundwater, oil and gas are not rock properties. However they

can tell us something about rock properties in their surroundings.
