What happened to iridium during Earth’s formation?
Iridium is a rare, silvery-white and hard metal that is found in small quantities in Earth’s crust. However, much of the world’s iridium is believed to have come from outer space, in the form of meteorites and asteroids that collided with our planet millions of years ago.
During the Earth’s formation, around 4.6 billion years ago, the planet was still in its molten state. This meant that the heavier elements like iron, nickel, and iridium would have sunk towards the center of the planet due to gravity, while the lighter elements like oxygen and silica would have risen to the surface, leading to the formation of the planet’s crust.
Many scientists believe that a massive asteroid impact, some 65 million years ago, played a crucial role in depositing large amounts of iridium on the Earth’s surface. This event is commonly known as the K-T extinction event, during which it is believed that a massive asteroid impact wiped out the dinosaurs and many other species.
When the asteroid collided with the Earth, it released a huge amount of energy, which vaporized the iridium present on the asteroid’s surface. The vaporized iridium then traveled into the Earth’s atmosphere and eventually settled on the planet’s surface along with other asteroid debris. This iridium layer has been found in various locations across the globe and is known as the “K-T boundary.”
Though iridium was present during the formation of Earth, it is believed that much of the planet’s iridium came from outer space, in the form of meteorites and asteroids. The impact of these celestial bodies on Earth led to the deposition of large amounts of iridium on the planet’s surface, with one of the most significant events being the K-T extinction event.
Therefore, iridium played a crucial role in shaping the Earth’s geological history and understanding the patterns of its occurrence can aid researchers in studying the Earth’s formation better.
What is an unusual fact about iridium?

However, the most remarkable property of iridium is its high density, which is almost twice as much as that of lead. This makes iridium one of the densest elements known to exist, with a density of 22.56 g/cm³. Besides, iridium is also one of the most corrosion-resistant metals, which makes it suitable for various high-temperature and high-pressure applications, such as spark plugs and crucibles.
One of the most interesting aspects of iridium is its role in the debate over the origin of life on Earth. In the 1970s, a team of scientists led by Luis Alvarez discovered a thin layer of iridium in sediments from the Cretaceous-Paleogene boundary. This layer, known as the K-T boundary, was found to coincide with the mass extinction event that wiped out the dinosaurs and many other species some 66 million years ago.
The discovery of iridium in the K-T boundary led to the hypothesis that a massive asteroid impact was responsible for the mass extinction event. This theory, known as the Alvarez hypothesis, became widely accepted among scientists and was supported by subsequent evidence, such as the discovery of the Chicxulub crater in the Yucatan peninsula.
The Chicxulub impact, which occurred about 66 million years ago, is believed to have released a massive amount of energy, causing a global cataclysm that led to the extinction of the dinosaurs.
Iridium is a fascinating element with many unusual properties and applications. Its high density, corrosion resistance, and role in the K-T boundary make it a valuable tool for scientists studying the origins of life and the history of our planet.
