Same old, same old

Origin stuff from 50 million years after the solar system formation 4.5 billion years ago, is still being extruded, exploded (or created, transformed) on our planets surface.

plate tectonics regurgitation expanding earthEarth's mantle is made of solid rock that nonetheless circulates slowly over millions of years. Some geologists assume that this slow circulation would have wiped away any geochemical traces of Earth's early history long ago. But a new study of volcanic rocks that recently erupted from volcanoes in Hawaii and Samoa reveals surprising geochemical anomalies - the 'fingerprints' of conditions that existed shortly after the planet formed.

With relatively near genesis material still found to be coming out from the surface is less and less of the planets inner material recycled and regurgitated?

plate tectonics recycling growing earth"Nearly all of these anomalies formed within the first 50 million years after the solar system formed," Mundl said. "Higher than normal levels of tungsten-182 are seen in very old rocks that most likely contained a lot of hafnium long ago. But lower levels of tungsten-182 are rare, and resemble what we might expect to see deep beneath the surface, in or near the planet's metallic core."

Who left their fingerprints at the crime scene?

Could peer reviewed science be right? Could these original element compounds have been unchanged for 4.5 billion years?

If the material was much younger than geology theory suggests could it have survived a shorter period of time?

If there was 'simple' globe expansion outwards and not classical plate tectonics with its at least seven supercontinents formations and breakups, could unchanged planet formation material still be beneath us?
