Sulfur-rich Carbonaceous Nanoglobules in the Tagish Lake Meteorite

Introduction: Understanding the distribution, chemistry, and structure of C in carbonaceous chondrites (CC) is fundamental to revealing information on early solar chemical evolution. The Tagish Lake CC has generated much interest partly because of its pristine nature and high C content [1,2,3]. Unique to the Tagish Lake CC are hollow carbonaceous nanoglobules [4]. These particles are morphologi...

Lithologically-dependent Bulk Isotopic Variations of Insoluble Organic Matter in the Tagish Lake Meteorite

Introduction: The Tagish Lake meteorite is an ungrouped carbonaceous chondrite that contains a high amount of organic carbon (up to 2.6 wt%), most of which is insoluble in polar solvents [1]. Lithologically, the Tagish Lake meteorite is anything but homogeneous. Aside from the carbonate-rich and carbonate-poor lithologies described by [2], there exist matrix-rich and matrix poor lithologies as ...

The Tagish Lake meteorite: a possible sample from a D-type asteroid.

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. T...
