Few days to apply for this #PhDposition in Precambrian mudstone metal enrichment. Are you the person to solve what happened during the Shunga event? It was a global deposition event of vast amounts of organic-rich mud in the coastal ocean that followed the Great Oxidation Event.
📢PhD opportunity!.Do you want to study depositional environment and organic/hydrothermal metal enrichment in 2 Ga old sediments?.#PhDPosition is for 3 years and in the #MSCA Doctoral Network #FluxBEATS - @GTK_FI @GeoHelsinkiUni.

The new Finnish stratigraphic classification guidelines also consider the Baltic Sea sediments.
This peer-reviewed volume is a revision of stratigraphic procedures and nomenclature in Finland. It provides practical guidance on the appropriate use of geological unit terminology in the Fennoscandian Shield area. .#Bedrock #Stratigraphy #Quaternary

Syvänmeren rautamangaaninodulit tuottavat happea hydrolyysillä. Huippumielenkiintoinen ja tärkeä löytö, mutta samalla hämmentävä osoitus siitä, miten valtamerten syvyyksissä on yhä löydettävissä eliökunnan olemassaolon kannalta keskeisiä ilmiöitä.

Merenpohjassa olevat metallipaakut, noduulit, paljastuivat tutkimuksessa happitehtaiksi. Mullistava löydös herättää uutta kritiikkiä syvänmeren kaivostoiminnan eettisyydestä.
