Final answer:
Primitive stones are the type of meteorites that include chondrites with chondrules. Carbonaceous meteorites are a subgroup of these that contain carbon and organic molecules, and are found in the outer asteroid belt.
Step-by-step explanation:
The type of meteorites that include chondrites, with their small glassy particles known as chondrules, are known as primitive stones. These meteorites are significant because they are thought to date back to the origin of our solar system, around 4.5 billion years ago. Majority of these meteorites are composed of silicates with some metallic grains. Among them, the carbonaceous meteorites stand out due to their content of carbon and various complex organic molecules, which on Earth, are fundamental to life.
Some carbonaceous meteorites also contain chemically bound water and are depleted in metallic iron, differentiating them from other meteorite types. The carbonaceous asteroids, often associated with these meteorites, are mostly found in the outer part of the asteroid belt. Understanding meteorites and their classifications, such as irons, stones, and stony-irons, provides critical insight into the early history of the solar system and the formation of planets.
