Taphonomy of very ancient microfossils from the similar to 3400 Ma Strelley Pool Formation and similar to 1900 Ma Gunflint Formation: New insights using a focused ion beam

Abstract:

Focused ion beam (FIB) milling permits the accurate extraction of ultrathin (c. 100. nm) cross sectional lamellae from microfossils found in geological thin sections. Subsequent TEM analysis of these lamellae can provide unique insights into the ultrastructure, chemistry and taphonomy of Precambrian microfossils at the micrometer to nanometer scale. Combining serial FIB milling with SEM imaging extends this capability to three dimensional (3D) tomographic reconstruction and visualization of P...
