Do you want to learn how to recognise and interpret rocks in the field and laboratory? In this course you will learn about basic geological concepts around the formation, evolution and deformation of rocks and geological structures in the solid earth. It will be divided into three sections; (i) sedimentology (ii) geological structures and (iii) igneous and metamorphic petrology. Part (i) deals with the formation of sedimentary rocks over a variety of depositional environments. Part (ii) is concerned with recognition and interpretation of basic geological structures such as faults and folds. Part (iii) covers the formation of magmas, igneous rocks and rock-forming silicate minerals, and the mineralogy and textures of metamorphic rocks.
Upon successful completion, students will have the knowledge and skills to:
- Classify rocks in hand specimen, in the field and in thin sections.
- Identify diverse sedimentary depositional environments from sedimentary structures.
- Recognise structures produced by simple crustal deformation.
- Map and quantitatively describe structures in simply folded and faulted regions in the field.
- Identify common rock-forming silicate minerals in thin sections in situ.
- Describe and recognise basic silicate mineral structures and formulas.
- Explain the pressure and temperature conditions and the geological settings in which these minerals form.
- Develop communication and teamwork skills while mapping in the field.
Parts of the assessment items and field-trip reports will require the students to undertake carefully curated literature based research and present the outcomes in reports. The content of the course as presented in lectures, flipped-resources and practical sessions will emphasis the progression from observation and quantitative measurement of geological phenomena, to formation and testing of hypotheses to explain those hypotheses, to modification of hypotheses.
There will be a compulsory short field trip to the Molonglo Gorge on March 3 in the practical session (from 12:00 pm until 5:00 pm).
There will be a compulsory field trip to the Wee Jasper area, west of Canberra from April 6-11, 2021. The focus will be on sedimentology and structural geology.
Students who are studying the course remotely and cannot attend these field trips will be given an alternative learning and assessment item to cover this material.
Additional Course Costs
Field trip costs will be $TBA per student for the Wee Jasper trip.
No additional resources are required.

Academic integrity is a core part of the ANU culture as a community of scholars. At its heart, academic integrity is about behaving ethically, committing to honest and responsible scholarly practice and upholding these values with respect and fairness.
The ANU commits to assisting all members of our community to understand how to engage in academic work in ways that are consistent with, and actively support academic integrity. The ANU expects staff and students to be familiar with the academic integrity principle and Academic Misconduct Rule, uphold high standards of academic integrity and act ethically and honestly, to ensure the quality and value of the qualification that you will graduate with.
The Academic Misconduct Rule is in place to promote academic integrity and manage academic misconduct. Very minor breaches of the academic integrity principle may result in a reduction of marks of up to 10% of the total marks available for the assessment. The ANU offers a number of online and in person services to assist students with their assignments, examinations, and other learning activities. Visit the Academic Skills website for more information about academic integrity, your responsibilities and for assistance with your assignments, writing skills and study.
You will be required to electronically sign a declaration as part of the submission of your assignment. Please keep a copy of the assignment for your records. Unless an exemption has been approved by the Associate Dean (Education) submission must be through Turnitin.
For some forms of assessment (hand written assignments, art works, laboratory notes, etc.) hard copy submission is appropriate when approved by the Associate Dean (Education). Hard copy submissions must utilise the Assignment Cover Sheet. Please keep a copy of tasks completed for your records.
Late submission permitted. Late submission of assessment tasks without an extension are penalised at the rate of 5% of the possible marks available per working day or part thereof. Late submission of assessment tasks is not accepted after 10 working days after the due date, or on or after the date specified in the course outline for the return of the assessment item. Late submission is not accepted for take-home examinations.
Accepted academic practice for referencing sources that you use in presentations can be found via the links on the Wattle site, under the file named “ANU and College Policies, Program Information, Student Support Services and Assessment”. Alternatively, you can seek help through the Students Learning Development website.
Assessment items will be returned after grading during lab classes. It is expected that assessment items should be returned within two weeks of the hand-in date.
Extensions and Penalties
Extensions and late submission of assessment pieces are covered by the Student Assessment (Coursework) Policy and Procedure. Extensions may be granted for assessment pieces that are not examinations or take-home examinations. If you need an extension, you must request an extension in writing on or before the due date. If you have documented and appropriate medical evidence that demonstrates you were not able to request an extension on or before the due date, you may be able to request it after the due date.
Resubmission of Assignments
Resubmission of assessment items is permitted on agreement of the convenor
Distribution of grades policy
Academic Quality Assurance Committee monitors the performance of students, including attrition, further study and employment rates and grade distribution, and College reports on quality assurance processes for assessment activities, including alignment with national and international disciplinary and interdisciplinary standards, as well as qualification type learning outcomes.
