The role of magmas in the formation of hydrothermal ore deposits. Influence of transition metal complexes on atmospheric droplet acidity. Breathing metals as a way of life: geobiology in action. A shift in global volcanic metal emissions may have occurred in Earth’s past as more oxidized, water-rich magmas became prevalent, influencing the surface environment. Although global arc magma chemistries vary considerably, our findings suggest that volcanic emissions in arcs have a distinct fingerprint when compared with other settings. We propose that volcanic metal emissions are controlled by magmatic water content and redox: hydrous arc magmas that do not undergo sulfide saturation yield metal-rich, saline aqueous fluid shallow degassing and resorption of late-stage sulfides feeds volcanic gases in Hawai’i and Iceland. As well as emitting higher fluxes of metals (similar to those building ore deposits), these arc emissions possess a distinct compositional fingerprint, particularly rich in tungsten, arsenic, thallium, antimony and lead when compared with those from hotspots. Here we compare measurements of arc basaltic volcano metal emissions with those from hotspot settings. I also added the entry in /etc/pam.d/system-local-login back in, as described by the Arch Wiki (link in first post).As well as gases that regulate climate over geological time, volcanoes emit prodigious quantities of metals into the atmosphere, where they have key roles as catalysts, pollutants and nutrients. Currently I still get the ("Settings need to be unlocked" message in Gnome Settings, but I really don't care about this right now, as long as it works). Reset Fingerprint Data in BIOS (Security -> Fingerprint)Īfter doing this the authentication works as expected. So if you're not using Windows, but want to use the fingerprint reader, you need to:ĭisable "Predesktop Authentication" in BIOS (Security -> Fingerprint) The problem is, that the device is therefore claimed by the BIOS first (this is where the "device is already claimed" error comes from, I guess) and meant to be handed over to Windows (!). There is something called "Predesktop Authentication", and as far as I understand it, this allows to use the fingerprint reader before boot. According to this issue, this is a problem with the BIOS.
