The proposed project aims to investigate in situ and characterize at micrometer and nanometer scales 3.3 billion year (Ga) filamentous structures (few micrometers in diameter) embedded in chert veins and carbonaceous-bearing lamina from the Barberton greenstone belt, South Africa, identified in petrographic thin sections of rock. The filamentous structures are clearly syngenetic with a carbonaceous composition as observed by optical and Raman microscopy.

Abstract
The proposed project aims to investigate in situ and characterize at micrometer and nanometer scales 3.3 billion year (Ga) filamentous structures (few micrometers in diameter) embedded in chert veins and carbonaceous-bearing lamina from the Barberton greenstone belt, South Africa, identified in petrographic thin sections of rock. The filamentous structures are clearly syngenetic with a carbonaceous composition as observed by optical and Raman microscopy.File in questo prodotto:
