DESCRIPTION - summary of the module content

This module builds on Mineral Deposit Geology (CSM3046) and Ore Deposit Geology (CSM M109) to provide a more in depth understanding of the nature and formation of ore mineral deposits. You will critically evaluate models for the formation of ore deposits with reference to data from case examples. Your understanding will be enhanced through detailed studies of mineral assemblages and textures in hand specimens, thin section and polished blocks. The module will develop skills for the study of ore mineral assemblages by reflected light microscopy. The module is not suitable for non-specialist students or interdisciplinary pathways.

PRE- / CO-REQUISITE MODULES – Either Mineral Deposit Geology (CSM3046) as prerequisite, or Ore Deposit Geology (CSM M109) as co-requisite.

 

AIMS - intentions of the module

To develop an understanding of the techniques that are employed to study metalliferous ore deposits.

To critically evaluate published models for the formation of ore deposits.

To further develop the student’s recognition and understanding of ore-related minerals by the use of hand specimens, transmitted and reflected light microscopy. To enhance the student’s ability to record and interpret mineral textures to improve their understanding of ore genesis and to test published deposit models. To develop an understanding of common techniques used for the development of petrogenetic models (mineralogy, geochemistry, fluid inclusion studies).

 

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

On successful completion of this module you should be able to:

 

Module Specific Skills and Knowledge

1. Explain the nature and economic significance of a range of metalliferous ore deposits.

2. Provide a critical evaluation of published models for the formation of ore deposits.

3. Recognise a wide range of ore-related minerals and be able to interpret ore textures to text and develop models for their formation.

 

Discipline Specific Skills and Knowledge

4. Record observations and data, evaluate these with reference to published conceptual models and from this to make geological interpretations.

 

Personal and Key Transferable / Employment Skills and Knowledge

5. Develop hypotheses which can be tested through the collection and analysis of multiple types of data.

6. Give an oral presentation and prepare a written report to professional standards.

 

SYLLABUS PLAN - summary of the structure and academic content of the module

The module will develop aspects of ore deposit research through examples of magmatic-related; magmatic-hydrothermal; hydrothermal; and surface deposits.

 

- Introductory overview of ore deposit classification and nomenclature.

- Introduction to ore mineralogy and petrography.

- The interpretation of ore paragenesis and mineralogy in the study of ore formation.

- The use of mineral chemistry for ore formation.

- The use of major and trace element geochemical data for mineral deposits.

- The use of stable and radiogenic isotope geochemistry for ore deposit studies.

- The use of fluid inclusions in ore deposit studies.

 

- Students will through group work and seminars critically examine published (and unpublished) ore deposit models with reference to specific case examples. Group presentations will be used to initiate discussions around the weight and balance of evidence for ore formation in different scenarios, and suggest ways that the evidence can be improved.

 

- Practical sessions will develop skills for ore mineralogy and petrography using reflected light microscopy, hand specimens and transmitted light microscopy where appropriate. They will further develop skills for the manipulation of analytical data for the purpose of development of petrogenetic models.
