Course Description

This is an advanced course taught to Master of Science in Geology students.

It is an in-depth treatment of economic mineral deposits world-over. The course is divided into four parts. Part 1 dwells on general fundamental principles of formation of ore deposits, exploration techniques, ore sampling and mining and environment. Part II handles different types of ore deposits and classic examples around the world. Part III is the practical component of the course. Part IV is a seminar topic a student researches upon.

The major topics of the course are:

Fundamental Principles of Ore Genesis

Mineral Exploration Techniques

Ore Sampling, Reserve Calculations and Mineral Economics

Mining and the Environment

World-Class Ore Deposits

Seminar on Research Topic

Course Objectives

These are:

To inculcate the knowledge of ore formation into students involving advanced studies such as fluid inclusions and isotopes.

To furnish the students with information concerning the distribution of mineral deposits around the earth.

To impart the knowledge of mineral exploration to the students to prepare them for independent projects of their own.

To train students in research methods in the discipline of mineral deposits and their exploration.

Teaching and Assessment Pattern

Duration of Course:

The course is taught to the MSC 1 students in one 15-week semester. It is a

3 credit unit course with two hours of lectures and 1 contact hour for practicals per week.

Mode of Instruction

Instruction by lectures

Weekly quizzes to the students to enable them to be participatory.

Both oral and written quizzes are given to the students.

Weekly practicals that will be assessed. Practicals will involve library and internet search on the beneficiation methods, uses and world-class examples of the handspecimen sample being investigated.

3

Assignments will be given to students after every major topic.

One day trip in Migadde area on Bombo road to practice mineral exploration and sampling methods.

Students will sit a course test after part I and another course test after part II.

Each student will be assigned a seminar topic for library and internet research. Towards the end of the semester the findings will be presented in form of a lecture by the student. Both the oral presentation and write-up will be assessed.

Assessment Pattern

The assessment of the students will be based on the following:
