The Polonnaruwa meteorite: oxygen isotope, crystalline and biological composition

📝 Original Info

• Title: The Polonnaruwa meteorite: oxygen isotope, crystalline and biological composition

• Date: 2013-03-11
• Authors: Researchers from original ArXiv paper

📝 Abstract

Results of X-Ray Diffraction (XRD) analysis, Triple Oxygen Isotope analysis and Scanning Electron Microscopic (SEM) studies are presented for stone fragments recovered from the North Central Province of Sri Lanka following a witnessed fireball event on 29 December 2012. The existence of numerous nitrogen depleted highly carbonaceous fossilized biological structures fused into the rock matrix is inconsistent with recent terrestrial contamination. Oxygen isotope results compare well with those of CI and CI-like chondrites but are inconsistent with the fulgurite hypothesis.
