Chris RowanAn interesting study of the hypothesis that the Sturtian "Snowball Earth" event from around 720-660 Mya was caused by a Large Igneous Province eruption, through a very comprehensive exploration of model parameter space.<a href="https://agupubs.onlinelibrary.wiley.com/doi/epdf/10.1029/2024JE008701?af=R" rel="nofollow noopener" translate="no" target="_blank">https://agupubs.onlinelibrary.wiley.com/doi/epdf/10.1029/2024JE008701?af=R</a>The basic idea: the Franklin LIP, now in northern Canada, erupted at low latitudes: this led to enhanced silicate weathering that removed of CO2 from the atmosphere fast enough for the (positive) ice-albedo feedback to overcome the (negative) silicate weathering feedback. The question asked here: could this mechanism work, and if it did, why didn't more recent LIP eruptions at tropical latitudes have similar effects? The answer: yes, under certain conditions that are more easily met in the Neoproterozoic than the Phanerozoic:- low starting temperatures - rapid weathering & erosion, possibly due to (lack of) plant cover - a weaker silicate weathering feedback<a href="https://scicomm.xyz/tags/geology" class="mention hashtag" rel="nofollow noopener" target="_blank">#geology</a> <a href="https://scicomm.xyz/tags/EarthHistory" class="mention hashtag" rel="nofollow noopener" target="_blank">#EarthHistory</a>

Chris RowanModelling suggests that Earth's first crust, which fractionated from a magma ocean, would have had a similar trace element composition to modern continental crust: in other words, this signature is not a reliable marker of subduction and plate tectonics on the young Earth.<a href="https://scicomm.xyz/tags/geology" class="mention hashtag" rel="nofollow noopener" target="_blank">#geology</a> <a href="https://scicomm.xyz/tags/tectonics" class="mention hashtag" rel="nofollow noopener" target="_blank">#tectonics</a> <a href="https://scicomm.xyz/tags/EarthHistory" class="mention hashtag" rel="nofollow noopener" target="_blank">#EarthHistory</a><a href="https://www.livescience.com/planet-earth/geology/study-reveals-flawed-argument-in-debate-over-when-plate-tectonics-began" rel="nofollow noopener" translate="no" target="_blank">https://www.livescience.com/planet-earth/geology/study-reveals-flawed-argument-in-debate-over-when-plate-tectonics-began</a>

Chris RowanThe protoplanetary material that coalesced to form the Earth had lots of intrinsic hydrogen bound with sulphur - probably enough to support hypothesis that Earth's water came from outgassing of mantle rather than being supplied by comets and asteroids. <a href="https://scicomm.xyz/tags/geology" class="mention hashtag" rel="nofollow noopener" target="_blank">#geology</a> <a href="https://scicomm.xyz/tags/planets" class="mention hashtag" rel="nofollow noopener" target="_blank">#planets</a> <a href="https://scicomm.xyz/tags/EarthHistory" class="mention hashtag" rel="nofollow noopener" target="_blank">#EarthHistory</a><a href="https://www.earth.ox.ac.uk/article/scientists-uncover-crucial-evidence-origin-water-earth" rel="nofollow noopener" translate="no" target="_blank">https://www.earth.ox.ac.uk/article/scientists-uncover-crucial-evidence-origin-water-earth</a>
