I've been working as part of the BASE project for the last 18 months, drilling the 3.22 billion year old Moodies group in South Africa to get fresh unweathered material in the least deformed sections. We finished drilling late last year, and last week we were able to sample the core.

To say this material is well preserved is an understatement. It's better preserved than some Phanerozoic material I've worked with.

My role will be to look for organic walled microfossils in the fine grained sedimentary rocks. Previous researchers found some large organic spheres in the Moodies in 2010, but those rocks were from a gold mine and the spheres were badly preserved. Our material has not been affected by hydrothermal gold mineralisation so we are hoping to find some nice fossils. Regardless, as you can see below, the microbial textures are beautifully preserved with lots of primary features.

Here's the paper talking about the fossils from 2010

🌍✨ Age of Earth’s Oldest Life Forms: Stromatolites, microbial structures dating back over 3.5 billion years, are a window into the origins of life on Earth. 🦠

Estos son los Domos del Arqueano. Una poza única en Cuatro Ciénegas a la que me dedicaré a conocer íntimamente por 5 años. Lo más importante que tengo que decir de este sitio, que es único entre lo único, es que podría ser una representación de cómo vivían posiblemente las primeras comunidades por allá por las épocas del Arqueano hace 4 000 ma. Si uno quisiera descubrir los secretos de como sobrevivió la vida... Este sería el sitio perfecto. #cuatrocienegas #microbialmats #evolución #ecology #originoflife #conservacionambiental #salvemoselplaneta #salvemoselagua (en Cuatro Ciénegas, Coahuila) https://www.instagram.com/p/B2r-T5oF_kt/?igshid=aen30hlbcm7h

An extreme close up of a microbial mat in a Proterozoic black shale. You can clearly see all the microbial filaments, especially in the bright cherty areas. The orange brown is the clay berthierine stained by organic matter. Image is ~0.1 mm wide.

This sample consists of black wrinkly microbial mats, and green grey claystone from the 1.4 billion year old Velkerri formation, from northern Australia. The mats were dominated by cyanobacteria living on the bed of a shallow sea that covered northern Australia at the time. The organic matter contained lots of sulphur which was converted into pyrite during burial. You can sea the pyrite as the sparkly gold flecks in the close up of the black mats. This area of the sea was far from land so instead of depositing grains eroded from existing rocks, like sand, sediment chemically precipitated from the sea water. The sea was rich in iron and silica and so iron silicate clays formed on the sea bed. The iron is green because they're was little oxygen around for it to react with. This process of chemical sedimentation is very slow and so there was plenty of time for the mats to grow across the sea bed. This also means that other material can accumulate on the sediment that would be lost in areas of rapid sedimentation. So I've also found lots of volcanic ash and spherules in these layers. I've also found mysterious grains in these samples which may be impact spherules from a meteor impact, or perhaps even micrometeors too. We don't know what the banding represents. It could be seasonal growth of the mats, it could reflect how nutrient abundance changes, or could effect changes in the rate if sedimentation. It could even reflect all our none of the above. I'm going through these samples, documenting the sedimentary textures and deciding which samples I want to turn into thin sections to examine under the petro microscope, and then to digest in acid to extract the fossils from. #geologyjohnson #geologist #geology #geologyrocks #sedimentary #microbial #microbialmat #precambrian #mesoproterozoic #fossil #fossils #stromatolite #Australia #green #shale #mudstone #earlylife #proterozoic https://www.instagram.com/p/Cc-dI2mNRVF/?igshid=NGJjMDIxMWI=
