A new type of carbonaceous chondrite, the Tagish Lake meteorite, exhibits a reflectance spectrum similar to spectra observed from the D-type asteroids, which are relatively abundant in the outer solar system beyond the main asteroid belt and have been inferred to be more primitive than any known meteorite. Until the Tagish Lake fall, these asteroids had no analog in the meteorite collections. The Tagish Lake meteorite is a carbon-rich (4 to 5 weight %), aqueously altered carbonaceous chondrite…

Tagish Lake--A Meteorite from the Far Reaches of the Asteroid Belt
Written by David W. Mittlefehldt NASA, Johnson Space Center Pieces of a 56-metric-ton meteorite rained down over a wide area of Canada on January 18, 2000. Many pieces landed on the frozen Tagish…
Migration of D-type asteroids from the outer Solar System inferred from carbonate in meteorites
Recent dynamical models of Solar System evolution and isotope studies of rock-forming elements in meteorites have suggested that volatile-rich asteroids formed in the outer Solar System beyond…
The Tarda Meteorite: A Window into the Formation of D-type Asteroids
Dynamic models of solar system evolution suggest that D-type asteroids formed beyond Saturn's orbit and represent invaluable witnesses of the prevailing conditions in the outer solar system. Here, we…
Mineralogy of Tagish Lake: An ungrouped type 2 carbonaceous chondrite
Abstract— In this paper we describe the recovery, handling and preliminary mineralogical investigation of the Tagish Lake meteorite. Tagish Lake is a type 2 carbonaceous chondrite which bears…
Organic Globules in the Tagish Lake Meteorite: Remnants of the Protosolar Disk
TLDR
Coordinated transmission electron microscopy and isotopic measurements of organic globules in the Tagish Lake meteorite shows that they have elevated ratios of nitrogen-15 to nitrogen-14 and deuterium to hydrogen, indicative of mass fractionation during chemical reactions at extremely low temperatures.
Meteoritic parent bodies: Their number and identification
Extensive collection efforts in Antarctica and the Sahara in the past 10 years have greatly increased the number of known meteorites. Groupings of meteorites according to petrologic, mineralogical,…
A novel organic-rich meteoritic clast from the outer solar system
TLDR
The X-ray micro-spectroscopic technique revealed that the OM aggregate has sp2 dominated hydrocarbon networks with a lower abundance of heteroatoms than in IOM from primitive (CI,CM,CR) carbonaceous chondrites, and thus it is distinguished from most of the OM in carbonaceous meteorites.
Lead Isotope Investigation of the Tagish Lake Carbonaceous Chondrite
Since chondritic meteorites (chondrites) are the most ancient known rocks in our Solar system, they provide unique opportunities to constrain the ages of planetary materials and objects that formed…
The first detection of water absorption on a D type asteroid
The D type asteroids are among the darkest objects known in our solar system. Here, we present infrared spectra of one of the main‐belt D type asteroids, 773 Irmintraud. In contrast to previous…
Origin and Evolution of Prebiotic Organic Matter As Inferred from the Tagish Lake Meteorite
TLDR
A systematic study of variations in the mineralogy, petrology, and soluble and insoluble organic matter in distinct fragments of the Tagish Lake meteorite finds that the variations correlate with indicators of parent body aqueous alteration.

The fall, recovery, orbit, and composition of the Tagish Lake meteorite: a new type of carbonaceous chondrite.
TLDR
The mineralogy, oxygen isotope, and bulk chemical composition of recovered samples of the Tagish Lake meteorite are intermediate between CM and CI meteorites, suggesting that the Tagishes Lake meteoroid may be one of the most primitive solar system materials yet studied.
Chips off of Asteroid 4 Vesta: Evidence for the Parent Body of Basaltic Achondrite Meteorites
TLDR
The sizes, ejection velocities of 500 meters per second, and proximity of these fragments to the 3:1 resonance establish Vesta as a dynamically viable source for eucrite, diogenite, and howardite meteorites.
Efficient delivery of meteorites to the Earth from a wide range of asteroid parent bodies
TLDR
It is found that the Yarkovsky effect significantly increases the efficiency of the delivery of meteorites to the Earth, while at the same time allowing a much wider range of asteroids to contribute to the flux of meteorite.
Small main-belt asteroid spectroscopic survey: Initial results
The spectral characterization of small asteroids is important for understanding the evolution of their compositional and mineralogical properties. We report the results of a CCD spectroscopic survey…

TLDR
Comparison with laboratory measurements on meteorites and Apollo 11 samples indicates that the surface of Vesta has a composition very similar to that of certain basaltic achondrites.
