Geology of Earth Resources Course objectives: The objectives of this course in Earth Resources are: (i) acquainting students (majors and non-majors) with the basic tools necessary for studying earth resources, (ii) understanding the different types of Earth resources, (iii) understanding the processes of formation of various economic ore deposits, (iv) understanding the processes and conditions necessary for the formation of oil and gas deposits, (v) understanding the relationship between the distribution of ores, oil, gas, and coal, and Plate Tectonics, and (vi) gaining some knowledge of the environmental problems associated with the extraction and utilization of earth resources. Textbooks: Most reading assignments will be from: "Ore Geology and Industrial Minerals: An introduction" by Anthony Evans. Additional readings will be assigned from a number of other textbooks, which are either available in the library, or will be placed in 228. Some lecture notes will be handed out throughout the semester. The students are advised not to rely entirely on the lecture notes which will only contain a brief outline of the subject matter, and are thus encouraged to take notes during lectures and do all the assigned reading. Field trips: This class has one field trip to a nearby area of some economic significance/ potential. Labs: Possible, depending on the emphasis/ curriculum/ departmental policy/ sample availability. Lab exercises would focus on textures of ore deposits, identifying ores, assessing reserves, identification of ore minerals using reflected light microscopy. Other Useful Textbooks Evans, A.
