Unit description Unit description
Lectures in this unit cover, at an introductory level, some of the important geophysical approaches which are used by Earth scientists to explore and understand the Earth's interior. Included are the methods of collecting and interpreting gravity, magnetic, seismic and electrical data and their use in assembling the presently held picture of the crust, mantle and core. Practical classes involve reducing and interpreting geophysical data from both exploration and global problems. An excursion provides an opportunity to carry out a field survey and interpret the results in terms of geological structure and environmental aspects.

Delivery and Resources

Required and Recommended Texts and/or Materials

The textbook for the unit is MUSSETT and KHAN (Looking into the Earth, 2000). The textbook will be available from the COOP Bookshop. Copies of the PowerPoint’s shown in the lectures will be available on the unit’s WEB page. The recommended textbook is an excellent text for second year, but you can also consider some of the third year textbooks as well.

The texts you should first consider are DENTITH AND MUDGE  (Geophysics for the Mineral Exploration Geoscientist, 2014); SHARMA (Environmental and Engineering Geophysics, 1997) and REYNOLDS (An Introduction to Applied and Environmental Geophysics, 1997), because they cover all the major geophysical topics, and are the recommended texts for the Exploration and Environmental Geophysics I (GEOS305) unit. They have the further advantage of consistently using the SI system of units.

In the past we used a text by SHARMA (Geophysical Methods in Geology, 2nd Ed, 1986), but this is now out of print. SHARMA covers the global aspect of geophysics in more detail and is a useful reference to have if you can find a 2nd hand copy. In 1998, we used PARASNIS (Principles of Applied Geophysics, 5th Ed) but a change in publisher meant a massive increase in its cost.

However, it is a useful text to refer to if you can find a 2nd hand copy. Other useful texts to consider are; TELFORD ET AL (Exploration, fairly mathematical); KEAREY & BROOKS (Exploration, current 3rd year exploration text); FOWLER (Good solid-earth coverage, used in GEOS386); SLEEP & FUJITA (Solid-earth, more mathematical). The solid earth aspect of this unit is best covered in FOWLER. It is strongly recommended that you have access to a geophysical textbook, particularly if you are studying externally.

Technology Used and Required

The unit also has a WEB site which can be found through the iLearn WEBSITE at https://ilearn.mq.edu.au/login/MQ/ .  This site contains information such as copies of colour images, copies of PowerPoint’s shown in class, and copies of the practicals that we do in class. The WEB site will also allow access to the digital version of the lectures recorded through the iLecture system. As well, this site will access the on-line quizzes that will need to be completed during the Session.  At the start of the year you should be issued with a username and password (Macquarie oneID) to access all the WEB sites available for the units you have taken. This will get you into the front page of the GEOS205 WEB site.

 

Information for students about access to online units is available at

https://ilearn.mq.edu.au/login/MQ/

I recommend that you use Mozilla Firefox as your browser, as it seems to have far less problems than Internet Explorer with iLearn
