Document Summary

Aka everything on the finals for the past 2 years. Generally exam questions will be either compare and contrast two deposits or describe one deposit (source of minerals, transport, and deposition (the trap)). Also should have an example of each deposit (canadian if possible). Based of course notes, lectures and mineral deposits 101 youtube videos. These will form in narrow but fairly continuous layers across the deposit through the body of the deposit. Small changes in temperature/chemistry of magma as new stuff enters the melt changes the crystallization and solubility of the solution quickly causing layers to drop out. Currents in melt will scour and concentrate the crystals in different areas. Deposits continue depositing as it cools with layers. Magmatic ni-cu sulphide deposits: mining: ni, cu, fe (pentlandite and chalcopyrite, astrobleme. Debate over whether mineral from meteor (leading theory) or from crack that opened up below, because of the impact.
