Figure 61 above. Australia EagleEye seismic tomography at 300 km, oil gas targeting.
This figure is of the Australian seismic tomography at 300 km depth with Eagle eye enhancement. This shows the warmer, red, and black areas, with slower seismic waves, under Australia.
Theoretically the zone above these hotter areas should be more favourable for oil and gas generation.
The hypothesis behind the oil and gas targeting is that gases and liquids containing hydrogen sulphide and the sulphur and different materials that facilitate the formation of oil and gas deposits will come up the same structures as the metal mineralising fluids.
Metal mines and hydrocarbons generally form in separate areas because hard brittle rocks where minerals deposit are not suitable for oil and gas retention.
Yellow outlines are current producing areas and are generally on the red or black areas. This substantiates the above hypothesis. The blue line encloses areas with similar heat flow that are not currently under production and are thus exploration targets.
