Abstract
Historically gold mining was an important contributor to the economy of<br>Tanzania. With the advent of better political and fiscal regimes exploration for<br>gold in the Archaean greenstones of the Tanzanian Craton is booming. Gold<br>mineralization is structurally controlled and often associated with sulphide and<br>alteration minerals. Geophysical surveys are mainly used to improve geological<br>and structural mapping and to locate associated sulphide mineralization or<br>alteration minerals. Three case histories are presented to describe the use of both<br>airborne and ground surveys during exploration.
