Description: Hello, I am selling Abadla 002, a rare CM2 Carbonaceous chondrite. This unique specimen weighs 1.642 grams and features a pleasing shape with visible chondrules. It sports a dark fusion-crusted exterior, and upon closer inspection, the broken surface reveals numerous small chondrules embedded in a dark gray matrix, constituting over 50% of the meteorite. Additionally, small CAIs are discernible. Scientists specializing in cosmochemistry have determined that CAIs were formed in close proximity to the Sun, likely within the orbit of Mercury when oxygen-16 levels were at their peak. The composition of oxygen-16 near the edge of inclusion A37 suggests that the CAI underwent a journey to regions further from the Sun, possibly around the asteroid belt, before returning to regions closer to the Sun and eventually making its way back to the area where asteroids originated, eventually becoming part of the Allende meteorite's parent body. This movement echoes theories of material transport from the inner to the outer solar nebula, yet stands out as the first known case of small objects meandering back toward the Sun. The meteorite comes with a Certificate of Authenticity (COA) and a display case. Thank you for your interest and take care. CM2 carbonaceous chondrite meteorites are a type of meteorite that is considered rare and scientifically significant. They are named after the type of asteroid from which they originated, which is the C-type asteroid. These meteorites are rich in carbon compounds and organic materials, making them important in the study of the early solar system and the origins of life on Earth. The rarity of CM2 carbonaceous chondrites is due to the fact that they make up only a small percentage of all meteorites that fall to Earth. They are believed to be some of the most primitive and unaltered materials in the solar system, dating back to the earliest stages of its formation over 4.6 billion years ago. Scientists study these meteorites to gain insights into the conditions present in the solar nebula and the processes that led to the formation of planets. The importance of CM2 carbonaceous chondrite meteorites lies in their composition, which includes complex organic compounds, amino acids, and water-bearing minerals. These materials are crucial in understanding the chemical evolution of the early solar system and the potential for life to arise on other planets or moons. Studying these meteorites can provide valuable information about the building blocks of life and the processes that may have contributed to the origin of life on Earth. In conclusion, CM2 carbonaceous chondrite meteorites are rare and significant objects that offer a window into the early history of the solar system and the potential for life beyond Earth. Scientists continue to study these meteorites to unravel the mysteries of our cosmic origins and the fundamental building blocks of life. Name: Abadla 002 This is an OFFICIAL meteorite name.
