Science Shows Zircon Gems Once Covered Australia

Research in Western Australia shows super volcanoes erupted zircon gemstones.
The surface of Earth was once covered in diamonds, well a very close imposter anyway. Australian scientists have just found out that a super volcano spewed out zircon crystals all over Australia.  It is a gem stone in many more colors than diamond.

Samples from drilling in Western Australia showed particular crystals should have not been there. They were different from naturally occurring ones eroded from rocks. The "strangers" were 2,300km from their volcanic source.

The great distance from erupting volcanoes indicates that the volcanic explosions 106 million years ago were much larger than previously thought. Australia must have been a very violent place in the past. Many animals would have died out because of the eruptions.

First RNA Formed in Freshwater Pools Near a Volcano

Chemistry: Life began near an active volcano in a freshwater puddle.
Use your imagination and assume that life began in a puddle of fresh water near an active volcano. Molecules begin to "see" each other and unite into a larger whole. They become membranes, the envelopes of future life. Like a chicken's egg the membrane shell is the holding structure where chemicals are assembled for incubating lifeforms.

RNA was the first significant biological molecule. This has a basic form of repeating subunits. A simple molecule perhaps. but difficult for a primitive Earth to "create". Yet it came into existence. Membrane were required for chemicals to grow into RNA. The fatty, lipid molecules in membranes formed easily. Lipids assist the building of RNA, then it forms a protective coating. This was the first primitive cell.

As soon as some RNA replicated, lifeforms began to evolve becoming more complex. This occurred in fresh water which was heated and cooled probably close to a volcano. Cycles of changing temperatures caused chemicals to move around and become concentrated which was necessary for molecular synthesis to take place.

Volcanic Chain Found in Australia

Scientists have always said that Australia is the safest country on earth in regard to volcanic eruptions and earthquakes.  Now we find that this is totally wrong.  A massive volcanic chain has been discovered stretching from Hillsborough in central Queensland in a straight line down to Cosgrove in Victoria, then into the sea.

The Australian continent has moved right over the top of the chain leaving volcanoes under the sea in Bass Strait.  Yellowstone in North America is only a third as long as the new Australian hot spot.  It is unusual because it is not located on a tectonic plate boundary.  This type of volcanic chain was not thought to exist.

A weakness above a mantle plume has allowed volcanoes to break through to the surface.  The mantle is 3,000 kilometers below.  The Cosgrove hot spot could become active especially in the south where it is younger.  This could happen as the Australian tectonic plate is the fastest moving on the planet.

Active volcanoes normally exist where the mantle is less than 100 kilometers thick on average.  Cosgrove is 150 kilometers thick at its greatest.  This is not a law for activity.  Eruptions are still possible.  Seismic activity is occurring off the north coast of Tasmania.
