The dynamic earth II: global processes ( 6 points, SCA Band 2, 0.125 EFTSL)

Leader: Dr Bruce Schaefer

Offered:
Clayton Second semester 2006 (Day)

Synopsis: This unit focuses on the internal structure of the Earth and what drives plate tectonics and related magmatism/volcanism. In this unit, the internal anatomy of the Earth is compared to that of other terrestrial planets. We will study how and when rocks melt, and how melts evolve into a variety of magmatic rocks. We will also study how rocks are dated and how we determine the age of the Earth and the solar system. This will be accompanied by a one day field trip and a three-day hands-on field course and practical classes introducing minerals and rocks under the microscope.

Objectives: On completion of this unit, students will be able to: understand geological processes that show secular or cyclic change; to understand the long term evolution of the earth's climate system and short term climate impacts; to understand processes that may result in mass extinctions on Planet Earth; to understand how supercontinents are formed and destroyed; to understand metallogeny in the context of large-scale tectonic processes; to understand the dynamics of the earth's mantle and mantle crust relationships; to understand processes that result in cyclical variation of element and isotope abundances.

Assessment: Examinations (3 hours): 50% + Practical examination: 15% + Practical/fieldwork: 35%

Contact Hours: Two 1-hour lectures and three hours of practical/tutorial classes per week; a three day hands on field course and a one-day field trip.
