For meteorite hunters, the desert is a paradise like existence. The unique dry climate environment is a natural protected area to slow down meteorite oxidation. The terrain covered with yellow sand makes meteorites nowhere to escape, making the desert region a large meteorite collection site after Antarctica. Olive meteorite iron (commonly known as olive meteorite) is a rare type of meteorite that has been witnessed and discovered in the world. Due to its unique ornamental value, it is also one of the most expensive meteorite varieties.

The Imilac olive meteorite was discovered in the Atacama Desert of Chile as early as 1822. Although the discovery of Imilac olive meteorite was not widespread, it attracted the attention and search of meteorite hunters. However, each discovery had a mass of several kilograms. It was not until 2018 that meteorite hunters from Russia once again entered the Atacama Desert and found hundreds of thousands of grams of Imilac olive meteorite.

The Imilac meteorite was analyzed by Bruker MICRO-XRF M4 TORNADO, and we can see the distribution of elements and minerals. Kamacite (Fe, Ni): Kamacite is a metal alloy mainly composed of iron and nickel. It is a common component of iron meteorites, usually appearing in crystalline form. Taenite (Fe, Ni): Taenite is another iron nickel alloy found in meteorites. It has a different crystal structure from Kamacite and is typically rich in more nickel. Troilite (FeS): Troilite is a mineral composed of iron and sulfur. It is commonly found in iron meteorites and usually appears as small yellow particles. Schrebersite (Fe, Ni) 3P): Schrebersite is a phosphide mineral containing iron and nickel. It is commonly found in iron meteorites and is often associated with other minerals such as Taenite and Kamacite. Chromium (FeCr2O4): Chromium is a mineral composed of iron, chromium, and oxygen. The presence of Imilac meteorites indicates the inclusion of chromium rich substances during their formation process.

These minerals are distributed in olivine (Fe, Mg) 2SiO4) particles, further highlighting the unique composition and origin of the Imilc meteorite. This unique sample provides us with valuable information about geological and chemical processes in outer space. The analysis results of MICRO-XRF fluorescence on this sample can expand our understanding of the universe and appreciate the beauty of these extraterrestrial objects from a scientific perspective.
