Authenticity of the Life-bearing Polonnaruwa Meteorite

چکیده
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.

On the Cometary Origin of the Polonnaruwa Meteorite
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.

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 کاملOn the Authenticity of IELTS Academic Tests
The purpose of this paper was to investigate the authenticity of IELTS academic tests. Bachman and Palmer (1996, p. 23) define authenticity as “the degree of correspondence of the characteristics of a given language test task to the features of a target language task”. Authenticity is then an important aspect of testing since it describes the relationship between the test and the real world. Th...
متن کاملDetermination of Soil Moisture Content at Bukit Bunuh Meteorite Impacted Area using Resistivity Method and Laboratory Test
Determination of soil moisture content is of vital importance to many fields of study; civil engineering, hydrology, agriculture, geology, ecology and forestry. The occurrence of impact crater in Bukit Bunuh, a meteorite impacted area, made it an area of great interest to many researchers. In view of the process of impact cratering, the subsurface soil characteristics such as moisture content o...
