kondriitteja

Kondriitteja, often referred to as chondrites, are a class of stony meteorites. They are distinguished by the presence of chondrules, which are small, spherical silicate grains that are thought to have formed from molten droplets in the early solar system. These chondrules are typically millimeters in size and are embedded in a fine-grained matrix.

Chondrites are considered the most primitive type of meteorite because they have undergone relatively little alteration since their formation. This makes them invaluable to scientists studying the early history of the solar system, including the composition of the primordial solar nebula and the processes that led to the formation of planets.

The chemical composition of chondrites is remarkably similar to that of the Sun, after accounting for the Sun's volatile elements like hydrogen and helium. This similarity further supports their status as representative samples of the material from which the Sun and planets formed.

There are several subtypes of chondrites, classified based on their mineralogy and chemical composition. The most common are ordinary chondrites, which are further divided into H, L, and LL groups. Other significant types include carbonaceous chondrites, known for their organic compounds and hydrated minerals, and enstatite chondrites, which are rich in the mineral enstatite. Studying these different types provides insights into the diverse conditions present in the early solar system.
