Economic Geology unit (KEA341)

Introduction

Human society is highly dependent on the use of a wide range natural resources including metals. But how do Earth systems concentrate widely dispersed metals into deposits that can be economically mined? This unit explains how a wide variety of metalliferous ore deposits are formed, including the fundamental chemical and physical processes responsible for metal transport and deposition. Unit content encompasses the broader environments that engender these processes, with particular emphasis on the most economically important styles of base metal and gold deposits. Topics covered include ore forming processes, hydrothermal alteration and ore genesis of the major hydrothermal deposit types. Practical exercises using samples from many world-class ore deposits (from Tasmania, Australia and the rest of the world) enable students develop skills in mineralogy, geochemistry and paragenesis, and the interpretation of a wide variety of macro- and micro-scale textural features for a variety of ore deposit types. This unit is one of six 300-level Earth Science units available to students in the Earth Sciences major, and is highly recommended for students who intend to become professional geoscientists.
