 Context examples 

According to the scientists, the collision provided sufficient carbonaceous material to account for the entire amount of water on Earth.

Ceres shares many commonalities with meteorites rich in water and organics — in particular, a meteorite group called carbonaceous chondrites.

In the new work at Goddard's Astrobiology Analytical Laboratory, Smith and her team analyzed samples from eight different carbon-rich meteorites, called CM-2 type carbonaceous chondrites and found vitamin B3 at levels ranging from about 30 to 600 parts-per-billion.

In particular, these models suggest that the Kuiper Belt — a cold region beyond the orbit of Neptune — should contain a small fraction of rocky bodies from the inner Solar System, such as carbon-rich asteroids, referred to as carbonaceous asteroids.

The measurements show that the molybdenum isotopic composition of the Earth lies between those of the carbonaceous and non-carbonaceous meteorites, demonstrating that some of Earth's molybdenum originated in the outer solar system.

After painstaking measurements from multiple instruments at ESO’s Very Large Telescope (VLT), the team led by Tom Seccull of Queen’s University Belfast in the UK was able to measure the composition of the anomalous Kuiper Belt Object 2004 EW95, and thus determine that it is a carbonaceous asteroid.

The scientists' results therefore show, for the first time, that carbonaceous material from the outer solar system arrived on Earth late.

(Moon’s Formation Brought Water to Earth, The Titi Tudorancea Bulletin)

While previous studies have shown that carbonaceous materials were likely responsible for delivering the water to Earth, it was unknown when and how this carbonaceous material—and thus the water—came to Earth.

(Moon’s Formation Brought Water to Earth, The Titi Tudorancea Bulletin)

The molybdenum isotopes allow us to clearly distinguish carbonaceous and non-carbonaceous material, and as such represent a 'genetic fingerprint' of material from the outer and inner solar system, explains Dr. Gerrit Budde of the Institute of Planetology in Münster and lead author of the study.

(Moon’s Formation Brought Water to Earth, The Titi Tudorancea Bulletin)

From earlier studies, we know that the solar system became structured such that the 'dry' materials were separated from the 'wet' materials: the so-called 'carbonaceous' meteorites, which are relatively rich in water, come from the outer solar system, whereas the drier 'non-carbonaceous' meteorites come from the inner solar system.
