.(a) Summarize the processes of magma generation, segregation, and evolution that account for the formation of ore deposits in magmatic environments.

(b) Using the Bushveld Complex as an example, describe the tectonic setting, magma types and specific commodities produced from the magmatic ore deposits there.

Question 2

(a) Summarize the processes related to the formation of diamond deposits generally. Include in your answer the rock types likely to host primary diamonds, the relationship between this host rock and its diamonds, the minimum depths where these rocks typically come from, their likely rates of ascent and the probable driving mechanism for ascent, their mineralogy and any rocks that you consider pertinent.

(b) Summarize the possible sources of carbon for the formation of diamonds and make an annotated sketch showing the tectonic environment where the primary sources of diamond can be found. (5 marks
