| Abstract |
Thermoluminescence is a thermally derived phenomenon, with the thermoluminescence signature of minerals and rocks in the geothermal setting strongly affected by alteration processes and natural heating. The technique has potential as a sensitive geothermal/geochemical sensor in geothermal systems. Laboratory analysis of quartz was undertaken to identify the effect of hydrothermal fluid in the Waiotapu Geothermal Field (New Zealand), and two-dimensional TL and spectroscopy of rock samples from Kamaishi mine (Japan) were measured. These results show possibilities of thermoluminescence techniques for geothermal exploration, and a new approach for geological applications. |
