A surface-based study on andrassy geothermal prospect for power generation

This surface-based geothermal study was conducted in the Andrassy geothermal prospect in Tawau and it consists of three parts. Firstly, the current state of geothermal activity was assessed through reconnaissance and geochemical study. Secondly, the ground surface thermal profile of the most prob...
