GEOLOGY 2505 - Geochemistry II

North Terrace Campus - Semester 2 - 2022

This course focuses on the chemistry of the natural world and the chemical evolution of the Earth over geological time. We will discuss practical and theoretical geochemistry, with an emphasis on how chemical principles are used to study Earth Sciences. The course is composed of three modules: (a) geochemical fundamentals; (b) natural and anthropogenically perturbed aspects of the Earth's hydrosphere and atmosphere and their interactions with rocks, sediments, soils and the biosphere; and (c) the origin and evolution of Earth (crust-mantle-core) through nuclear and high temperature chemical processes.

  • Learning & Teaching Activities
    Learning & Teaching Modes
    This course will be delivered by the following means:
    • 2 X 1-hour lectures
    • 1 X 2-hour workshops
    Workload

    The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

    A student enrolled in a 3 unit course, such as this, should expect to spend on average 12 hours per week on the studies required. This includes both the formal contact time required to the course (e.g., lectures and workshops), as well as non-contact time (e.g., reading, homework and revision).
    Learning Activities Summary
    This course covers the broad areas of:

    Geochemical Fundamentals

    • Thermodynamics and chemical reactions, solubility, pH and redox
    • The Elements; basic principles of inorganic chemistry, periodic properties
    Low temperature geochemistry - The hydrologic cycle and Sedimentary geochemistry
    • Aquatic chemistry and biogeochemistry: photosynthesis/respiration, carbon and nitrogen cycles, stable isotope and the water cycle.
    • Chemical weathering, soil formation, geochemistry of clays.
    • The geochemistry of the atmosphere: greenhouse gases, ozone, acid rain
    • The geochemistry of the oceans: carbonate chemistry, primary productivity, nutrient cycling and the marine sediment record.
    High temperature geochemistry 
    • Planet formation, differentiation of the Earth.
    • Evolution of the crust, mantle and core.
    • Trace element and Radiogenic isotope geochemistry/Geochronology
  • Assessment

    The University's policy on Assessment for Coursework Programs is based on the following four principles:

    1. Assessment must encourage and reinforce learning.
    2. Assessment must enable robust and fair judgements about student performance.
    3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
    4. Assessment must maintain academic standards.

    Assessment Related Requirements
    Attendance at workshops is compulsory for those workshops marked as such in the course syllabus - namely the initial introduction to each Problem Set and Project (5 items). Students are able to apply for an allowed absence from a class by submitting the application form with appropriate documentation to the Course Co-ordinator. Application forms can be downloaded from http://www.sciences.adelaide.edu.au/current-students/forms/savs-allowed-leaveofabsence-tute-prac.pdf. 
    Assessment Detail
    Lecture Tests: (45%)
    Test material comes primarily from lecture materials and assigned readings. The tests will consist of a mixture of  multiple choice and short/longer answer questions.

    Problem sets: (25%):
    These will serve to teach geochemistry tools, and how to apply them for critical analysis of data and interpretation of results.

    Projects: (30%)
    These will serve to teach geochemistry tools, and how to apply them for critical analysis of data and interpretation of results.
    Submission
    Late Submission
    If an extension is not applied for, or not granted then a penalty for late submission will apply. A penalty of 10% of the value of the assignment for each calendar day that the assignment is late (i.e. weekends count as 2 days), up to a maximum of 50% of the available marks will be applied. This means that an assignment that is 5 days late or more without an approved extension can only receive a maximum of 50% of the marks available for that assignment.
    Course Grading

    Grades for your performance in this course will be awarded in accordance with the following scheme:

    M10 (Coursework Mark Scheme)
    Grade Mark Description
    FNS   Fail No Submission

    Final results for this course will be made available through Access Adelaide.

  • Student Feedback

    The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

    SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

  • Student Support
  • Policies & Guidelines
  • Fraud Awareness

    Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
