Interesting stuff Jaros!
These Volcanic chains are part reason South-Eastern Australia has been in an active 'Mountain Building' stage for the past few million years due to tectonic plate shifting.
The main areas involved have been around Victoria's Otway Ranges, The Mornington Peninsula and Strzeleckis.
Geologists have most recently proved that Australia has not been lying geologically 'dormant' for the past 40 million years as once thought.
Tectonic movements have pushed the Otway's 250 metres higher in the past three million years, and the Selwyn fault, which runs from 'Mt Martha' on Victoria's Mornington Peninsula, east to the Dandenong Ranges, has possibly produced six metres of uplift in the past 100,000 years.
As most know, fault-lines provide the weakest point of resistance for rich gold bearing Hydrothermal fluids to travel under heat and pressure.
Most of the big mining companies mine fault-zones for this very reason.
Many of the South Australian members here will wonder why SA does not contain much gold, a main reason I believe is because it has the fewest fault-zone locations in all of Australia
Its very feasible that undiscovered rich gold deposits lie deep within The Otways, Mt Martha and The Strzelecki Ranges!
I think you may have given Silver 'Gold Fever' Jaros without even sneezing on him
Here is a map of Major Fault lines within our wide brown land.
From it you will see its no coincidence that the heavily faulted areas are all within our major gold producing areas in Oz!
