description Indarch Overview

Indarch is an EH4 enstatite chondrite that fell near Shusha in present-day Azerbaijan in 1891. Its highly reduced mineral assemblage includes abundant enstatite, iron-nickel metal, and sulfide minerals, with little iron bound into silicates. Researchers study Indarch to investigate the formation of enstatite chondrites and the oxygen-poor conditions that existed in parts of the early Solar System.

help Indarch FAQ

What type of meteorite is the Indarch meteorite?

Indarch is classified as an EH4 enstatite chondrite, which is a very rare type of stony meteorite. It is notable for its highly reduced mineral assemblage, meaning it formed in an environment completely devoid of oxygen.

When and where did the Indarch meteorite fall?

The Indarch meteorite fell near the town of Shusha in present-day Azerbaijan in the year 1891. The fall was observed, leading to the recovery of several stones that were subsequently analyzed by the scientific community.

What unusual minerals are found in the Indarch meteorite?

Instead of the more common minerals found on Earth, Indarch is composed primarily of enstatite, abundant iron-nickel metal, and rare sulfide minerals. There is almost no iron bound into silicates, which makes its chemistry fundamentally different from most other rocks.

Why do scientists study the Indarch meteorite?

Researchers study Indarch closely because enstatite chondrites are believed to be the building blocks that formed the planet Mercury. By analyzing Indarch's composition, scientists can learn about the highly reduced, oxygen-poor conditions of the early inner solar system.
