A Sample Of Zircon 35 Atom Of 207Pb for every 5 atoms of 235U. How Old Is Zircon? t(1/2)=5730.
K=0.693/704E6=9.8E-10
-1/K ln(5/90)= years
zircon is mined in: *Yitterby feldspar quarry, Stockholm *Finnbo and Kararvet, Falun *Hogsbo, Goteborg *As, Alnon *Penseryd and Stenberget, Romelasen, Skane *Storansen Medelpad *Seiland, Alta, Norway *Langesunsfjorden, Jordan *Oslo, Norway *Tordal, Norway Hopes this answers ur question! :) Worldwide. This is an interesting question to answer. Hello Aussie's, the oldest Zircon is 4.404 billion years old from Yilgam Craton Western Austrailia.

The earth is estimated to be around 4.5 billion years old. This estimate is taken from the oldest available zircon crystal which dates back to 4.4 billion years. The dinosaurs are expected to exist around 0.3 billion years ago.
It may be challenging to match DNA from a very old sperm sample due to degradation over time. However, advanced DNA analysis techniques like polymerase chain reaction (PCR) can sometimes help in obtaining usable genetic information for matching. The success of matching will depend on the extent of degradation and the quality of the sample.
The oldest zircon minerals on Earth are around 4.4 billion years old. These zircons were found in Western Australia and provide valuable insight into the early history of Earth's formation.
zircon-4.4 billion year old crystal
A tiny crystal of zircon discovered in Australia is the oldest record fragment of the earth. At between 4.3 and 4.4 billion years old, this tiny sample is 100 million years older than any previous dicovery.
The element zirconium was named after the mineral zircon, where it was first discovered. Zirconium is commonly found in zircon minerals and is often associated with other elements like silicon, hafnium, and thorium. The name zircon itself is derived from the Arabic word "zargun," meaning "gold-colored."

A tiny speck of zircon crystal that is barely visible to the eye is believed to be the oldest known piece of Earth at about 4.4 billion years old.
yes
The ratio of radioactive carbon-14 in the old sample to the current sample is 1:8, suggesting 3 half-lives have passed. Since each half-life is 5730 years, the age of the old sample would be approximately 17190 years.
The oldest known mineral on Earth is zircon, minute grains of which have been found in Australia and dated at over four billion years old.
