Review:
Calcium Aluminum Rich Inclusions (cais)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Calcium-aluminum-rich inclusions (CAIs) are some of the oldest known solid materials within meteorites, formed in the early solar system. They are tiny mineral grains composed primarily of calcium, aluminum, and oxygen, providing valuable insights into the processes that took place during the formation of the solar nebula about 4.6 billion years ago. CAIs are critical to understanding the initial conditions and chemical environment of our solar system's birth.</overview>
