Researchers have successfully confirmed the oldest rock fragments ever found on Earth. Researchers confirmed fragments of small zircon crystals in Australia as the oldest oldest rock fragment on Earth, reaching 4.37 billion. To note the age of Earth is currently 4.56 billion years. Zircon is a colorful mineral stone. "We have proven the chemical record in the zircon and it is undeniable," says John Valley, a University of Wisconsin, Florida Geochemist study leader, quoted by Live Science on Monday, February 24, 2014. The zircon element is one of the most difficult minerals in Earth. The dating of ancient Australian crystals shows the age of the fracture reached 165 million years after the formation of the Earth, but was then ingested in the process of forming the earth's core. The oldest zircon mineral age was previously thought to be present in rocks in the Jack Hill region, western western of Western Australia. To that end, geologists have carefully examined more than 100,000 zircons very little on Jack Hill, and dating shows in the early days of Earth, about 3 to 4.4 billion years ago. Tracking elements on the oldest zircon from Jack Hill indicate these minerals arise from granite-like rocks that are rich in water. This indicates that in the past the cooling of Earth's water ponds and the continental rocks, has been more rapid in just 100 million years after the events of the Moon's impact, a massive collision that later formed the Earth-Moon system.
