On the Cometary Origin of the Polonnaruwa Meteorite
نویسندگان
چکیده
The diatoms discovered in the Polonnaruwa meteorite are interpreted as originating in comets and the dust in interstellar space. The exceptionally porous structure of the Polonnaruwa meteorite points to it being a recently denuded cometary fragment. Microorganisms that were present in a freeze-dried state within pores and cavities may have survived entry to be added to the terrestrial biosphere.

Authenticity of the Life-bearing Polonnaruwa Meteorite
We show that the Polonnaruwa stones that were collected on 29 December 2012 following a witnessed fireball, in which we found biological structures, do not possess properties that are consistent with fulgurites on the basis of X-ray diffraction studies, and other data. The existence of distinct diatom frustules fused into the rock matrix makes recent contamination unlikely.
متن کاملThe origin of organic matter in the Martian meteorite ALH84001.
Stable carbon isotope measurements of the organic matter associated with the carbonate globules and the bulk matrix material in the ALH84001 Martian meteorite indicate that two distinct sources are present in the sample. The delta 13C values for the organic matter associated with the carbonate globules averaged -26% and is attributed to terrestrial contamination. In contrast, the delta 13C valu...
متن کاملLut 009, an H4 (S2, W4) ordinary chondrite meteorite from Lut Desert of Iran
Lut 009 meteorite was found during a trip to Lut Desert of Iran in March,2012, at 30°20.38' N, 59°09.04' E. Chemical compositions of equilibrated olivine (Fa19.3 ± 0.5) and orthopyroxene (Fs16.7 ± 0.6) show that the meteorite sample belongs to H group of ordinary chondrites, while the texture (chondrule petrography and plagioclase size) suggests a petrologic type of 4. The Lut 009 has been very...
متن کاملExperimental determination of scattering matrices of olivine and Allende meteorite particles
We have measured the scattering matrix as a function of the scattering angle of randomly oriented particles of a Mg-rich olivine sample and a ground piece of Allende meteorite as cometary analogues using lasers at two wavelengths (442 nm and 633 nm). The elements of the scattering matrix, Fij , depend on the scattering angle, the wavelength of the laser light, and on the size, shape and refract...
متن کاملFossil diatoms in a new carbonaceous meteorite
We report the discovery for the first time of diatom frustules in a carbonaceous meteorite that fell in the North Central Province of Sri Lanka on 29 December 2012. Contamination is excluded by the circumstance that the elemental abundances within the structures match closely with those of the surrounding matrix. There is also evidence of structures morphologically similar to red rain cells tha...
